Lock mechanisms are fascinating devices that have been relied upon for centuries to secure homes, businesses and personal belongings. Understanding how these mechanisms work can be a fascinating journey into the world of mechanical engineering, design and security. This essay will decode the functionality of different lock mechanisms for a deeper understanding of how they provide safety and security.
Firstly, we have the classic pin and tumbler lock. This type of lock is most commonly found in deadbolts and doorknobs. The mechanism consists of a series of spring-loaded pins that are divided into pairs, namely, key pins and driver pins. When a key is inserted into the lock, it pushes up the pins to align with the shear line, which allows the plug to rotate and unlock. Any misalignment prevents the plug from turning, keeping the lock secure.
Secondly, we have the wafer lock. Wafer locks work similarly to pin and tumbler locks, but instead of pins, they use wafer-shaped flat objects. When the correct key is inserted, the bittings on the key raise the wafers, aligning them perfectly to allow the plug to turn. These locks are commonly found in cabinets and cars due to their simplicity and cost-effectiveness.
Next is the disc tumbler lock or disc detainer lock. This type of lock uses slotted rotating detainer discs. The right key will align the slots, unblocking the sidebar and allowing the lock to open. These locks are known for their high security and are often used in high-security areas like bike locks and safes.
The tubular lock, also known as the radial lock, operates with a circular key. The key has several notches that align with pins inside the lock. Once aligned, the central post turns, opening the lock. Tubular locks are often used in vending machines and bike locks due to their resistance to lock picking.
Lastly, we have the smart lock. Unlike traditional mechanical locks, smart locks work electronically through a wireless protocol and a cryptographic key to execute the authorization process. They can be controlled remotely via smartphones, and some even include features like voice recognition, biometrics, and auto-locking.
In conclusion, different lock mechanisms offer varying levels of security and convenience. From the simple pin and tumbler to the high-tech smart lock, each lock has its unique functionality and application. Understanding these different mechanisms not only satisfies our curiosity but also aids in making informed decisions about our security needs.
Lock mechanisms are an essential aspect of our daily lives, providing security and peace of mind in our homes, offices, and vehicles. However, these mechanisms can fail due to a variety of reasons, such as wear and tear, improper use, or even due to a burglary attempt. In such cases, the role of emergency locksmiths becomes crucial in addressing these failures.
Emergency locksmiths are skilled professionals who specialize in repairing, replacing, and unlocking lock mechanisms of various types. Their importance in our society cannot be understated, as they provide an immediate solution to lock failures that can otherwise compromise our security and safety.
One of the primary roles of emergency locksmiths in addressing lock mechanism failures is their ability to provide immediate assistance. Lock failures tend to occur at the most inconvenient times, leaving us stranded or locked out. Emergency locksmiths are available round the clock, ready to respond swiftly and rectify the issue. Their quick response time ensures that we are not left in a vulnerable situation for long.
Emergency locksmiths are also adept at identifying and rectifying the cause of lock mechanism failures. They possess a deep understanding of different lock mechanisms, from traditional deadbolts to modern digital locks. This knowledge allows them to diagnose the problem accurately and perform necessary repairs or replacements. In situations where the lock has been damaged beyond repair, they can install a new lock mechanism, ensuring that the security is not compromised.
Moreover, emergency locksmiths play a vital role in maintaining the integrity of the lock mechanism during their interventions. They utilize specialized tools and techniques to unlock or repair the lock without causing additional damage. This skill is particularly important in cases where the lock is part of a larger security system, as any damage can render the entire system ineffective.
In addition to their technical skills, emergency locksmiths also provide reassurance and peace of mind during stressful situations. Dealing with a lock failure can be quite distressing, especially if it compromises our security or disrupts our daily activities. The presence of a professional locksmith can alleviate this stress, as they can quickly resolve the problem and restore our confidence in our security arrangements.
In conclusion, the role of emergency locksmiths in addressing lock mechanism failures is multifaceted and crucial. They provide immediate assistance, accurately identify and rectify the problem, maintain the integrity of the lock mechanism, and provide reassurance during stressful situations. Their expertise and professionalism ensure that we can rely on our lock mechanisms to provide the security we need.
Lock mechanisms, in their various forms, are designed to keep homes, businesses, and personal belongings safe. However, these mechanisms occasionally malfunction, leading to inconvenient and potentially risky situations. This essay aims to explore some common problems with various lock mechanisms from an emergency locksmiths perspective, thereby enhancing our understanding of different lock mechanisms and their potential vulnerabilities.
Firstly, one of the most common issues that a locksmith encounters is a key getting stuck or breaking inside a lock. This is prevalent in traditional pin and tumbler lock mechanisms, where the keys teeth align with the pins in the lock to allow it to turn. Keys can become worn over time, leading to them getting stuck or breaking. This is not only inconvenient but also a security risk as it can prevent the owner from accessing their property.
Faulty latch mechanisms are also frequently encountered by locksmiths. The latch or bolt of the lock may not catch properly in the strike plate, preventing the door from closing or locking. This problem is commonly seen in deadbolt locks, which rely on the bolt extending into the strike plate to secure the door.
Electronic lock mechanisms, such as those used in keyless entry systems, are not immune to problems either. They can suffer from software glitches, battery issues, or malfunctions with the key fob or card. Although these systems offer increased convenience and security, when they fail, they can leave users locked out, requiring the services of a skilled locksmith.
Another common problem is a lock becoming stiff or hard to turn. This can happen with any mechanical lock, but it is most commonly seen in cylinder locks. Over time, dust and dirt can build up in the lock, causing it to become stiff. In some cases, the incorrect lubricant can also cause the lock to seize up.
Lastly, lock bumping is a problem that affects many pin tumbler locks. This is a technique used by burglars to bump the pins inside the lock into position using a specially cut key, allowing them to open the lock without the correct key. This problem has led to the development of bump-proof locks, but these are not yet widespread.
In conclusion, while various lock mechanisms offer different levels of security and convenience, they all have their own set of potential problems. A deeper understanding of these lock mechanisms and their vulnerabilities can help us choose the most suitable lock for our needs and take preventative measures to avoid common issues. As the world continues to evolve with new technologies, so will our locking systems. It is the locksmiths who will help us navigate these changes, ensuring our safety and security in an ever-changing world.
Understanding the complexities of different lock mechanisms is crucial in todays technologically advanced world. Advanced lock mechanisms and the importance of professional emergency locksmith services are two key aspects that play an integral role in securing our homes, offices, and vehicles. The knowledge of these aspects not only helps in enhancing the security measures but also enables us to deal with lock-related issues effectively.
Advanced lock mechanisms are the epitome of modern-day technology that has transformed the conventional methods of securing our premises. These mechanisms are not confined to just traditional metallic keys but incorporate digital keys, biometric identification, remote access, and smart home integration. Features like anti-lock picking, anti-drill, anti-bump, and anti-snap have significantly increased the resistance of these advanced lock mechanisms against forced entry attempts. Therefore, understanding these mechanisms can help us choose the most suitable and robust security system for our premises.
However, with the advent of these advanced lock mechanisms, the task of installation, maintenance, and repair has become more complex and requires professional expertise. This is where the importance of professional emergency locksmith services comes into play.
Professional locksmiths are trained individuals who possess the necessary skills and tools to deal with all kinds of locks, be it traditional or advanced. They are well-versed with the intricacies of different lock mechanisms and can provide effective solutions to a variety of lock-related issues.

They can provide valuable advice on the use and maintenance of advanced lock mechanisms, thereby ensuring their long-term functionality.
Moreover, emergency locksmith services are available round the clock. Regardless of the time or location, these professionals can reach you in the shortest possible time and provide immediate assistance. This is especially crucial during emergencies when every second counts.
In conclusion, understanding advanced lock mechanisms and relying on professional emergency locksmith services is the key to maintaining a high level of security. Advanced lock mechanisms, with their innovative features, provide a robust defense against break-ins. On the other hand, professional locksmith services ensure the proper installation, maintenance, and repair of these mechanisms. Therefore, both these aspects are indispensable in securing our properties and ensuring peace of mind.
Lock(s) or Locked may refer to:
A lock is a mechanical or electronic fastening device that is released by a physical object (such as a key, keycard, fingerprint, RFID card, security token or coin), by supplying secret information (such as a number or letter permutation or password), by a combination thereof, or it may only be able to be opened from one side, such as a door chain.
A key is a device that is used to operate a lock (to lock or unlock it). A typical key is a small piece of metal consisting of two parts: the bit or blade, which slides into the keyway of the lock and distinguishes between different keys, and the bow, which is left protruding so that torque can be applied by the user. In its simplest implementation, a key operates one lock or set of locks that are keyed alike, a lock/key system where each similarly keyed lock requires the same, unique key.
The key serves as a security token for access to the locked area; locks are meant to only allow persons having the correct key to open it and gain access. In more complex mechanical lock/key systems, two different keys, one of which is known as the master key, serve to open the lock. Common metals include brass, plated brass, nickel silver, and steel. The act of opening a lock without a key is called lock picking.

Schlüssel#Geschichte_von_Schloss_und_Schlüssel
Locks have been in use for over 6000 years, with one early example discovered in the ruins of Nineveh, the capital of ancient Assyria.[1] Locks such as this were developed into the Egyptian wooden pin lock, which consisted of a bolt, door fixture or attachment, and key. When the key was inserted, pins within the fixture were lifted out of drilled holes within the bolt, allowing it to move. When the key was removed, the pins fell part-way into the bolt, preventing movement.[2]
The warded lock was also present from antiquity and remains the most recognizable lock and key design in the Western world. The first all-metal locks appeared between the years 870 and 900, and are attributed to English craftsmen.[3] It is also said that the key was invented by Theodorus of Samos in the 6th century BC.[1]
The Romans invented metal locks and keys and the system of security provided by wards.[4]
Affluent Romans often kept their valuables in secure locked boxes within their households, and wore the keys as rings on their fingers. The practice had two benefits: It kept the key handy at all times, while signaling that the wearer was wealthy and important enough to have money and jewellery worth securing.[5]
A special type of lock, dating back to the 17th–18th century, although potentially older as similar locks date back to the 14th century, can be found in the Beguinage of the Belgian city Lier.[6][7] These locks are most likely Gothic locks, that were decorated with foliage, often in a V-shape surrounding the keyhole.[8] They are often called drunk man's lock, as these locks were, according to certain sources, designed in such a way a person can still find the keyhole in the dark, although this might not be the case as the ornaments might have been purely aesthetic.[6][7] In more recent times similar locks have been designed.[9][10]
With the onset of the Industrial Revolution in the late 18th century and the concomitant development of precision engineering and component standardization, locks and keys were manufactured with increasing complexity and sophistication.[11]
The lever tumbler lock, which uses a set of levers to prevent the bolt from moving in the lock, was invented by Robert Barron in 1778.[12] His double acting lever lock required the lever to be lifted to a certain height by having a slot cut in the lever, so lifting the lever too far was as bad as not lifting the lever far enough. This type of lock is still used today.[13]
The lever tumbler lock was greatly improved by Jeremiah Chubb in 1818.[12] A burglary in Portsmouth Dockyard prompted the British Government to announce a competition to produce a lock that could be opened only with its own key.[5] Chubb developed the Chubb detector lock, which incorporated an integral security feature that could frustrate unauthorized access attempts and would indicate to the lock's owner if it had been interfered with. Chubb was awarded £100 after a trained lock-picker failed to break the lock after 3 months.[14]
In 1820, Jeremiah joined his brother Charles in starting their own lock company, Chubb. Chubb made various improvements to his lock: his 1824 improved design did not require a special regulator key to reset the lock; by 1847 his keys used six levers rather than four; and he later introduced a disc that allowed the key to pass but narrowed the field of view, hiding the levers from anybody attempting to pick the lock.[15] The Chubb brothers also received a patent for the first burglar-resisting safe and began production in 1835.
The designs of Barron and Chubb were based on the use of movable levers, but Joseph Bramah, a prolific inventor, developed an alternative method in 1784. His lock used a cylindrical key with precise notches along the surface; these moved the metal slides that impeded the turning of the bolt into an exact alignment, allowing the lock to open. The lock was at the limits of the precision manufacturing capabilities of the time and was said by its inventor to be unpickable. In the same year Bramah started the Bramah Locks company at 124 Piccadilly, and displayed the "Challenge Lock" in the window of his shop from 1790, challenging "...the artist who can make an instrument that will pick or open this lock" for the reward of £200. The challenge stood for over 67 years until, at the Great Exhibition of 1851, the American locksmith Alfred Charles Hobbs was able to open the lock and, following some argument about the circumstances under which he had opened it, was awarded the prize. Hobbs' attempt required some 51 hours, spread over 16 days.
The earliest patent for a double-acting pin tumbler lock was granted to American physician Abraham O. Stansbury in England in 1805,[16] but the modern version, still in use today, was invented by American Linus Yale Sr. in 1848.[17] This lock design used pins of varying lengths to prevent the lock from opening without the correct key. In 1861, Linus Yale Jr. was inspired by the original 1840s pin-tumbler lock designed by his father, thus inventing and patenting a smaller flat key with serrated edges as well as pins of varying lengths within the lock itself, the same design of the pin-tumbler lock which still remains in use today.[18] The modern Yale lock is essentially a more developed version of the Egyptian lock.
Despite some improvement in key design since, the majority of locks today are still variants of the designs invented by Bramah, Chubb and Yale.
A warded lock uses a set of obstructions, or wards, to prevent the lock from opening unless the correct key is inserted. The key has notches or slots that correspond to the obstructions in the lock, allowing it to rotate freely inside the lock. Warded locks are typically reserved for low-security applications as a well-designed skeleton key can successfully open a wide variety of warded locks.
The pin tumbler lock uses a set of pins to prevent the lock from opening unless the correct key is inserted. The key has a series of grooves on either side of the key's blade that limit the type of lock the key can slide into. As the key slides into the lock, the horizontal grooves on the blade align with the wards in the keyway allowing or denying entry to the cylinder. A series of pointed teeth and notches on the blade, called bittings, then allow pins to move up and down until they are in line with the shear line of the inner and outer cylinder, allowing the cylinder or cam to rotate freely and the lock to open. An additional pin called the master pin is present between the key and driver pins in locks that accept master keys, to allow the plug to rotate at multiple pin elevations.
A wafer tumbler lock is similar to the pin tumbler lock and works on a similar principle. However, unlike the pin lock (where each pin consists of two or more pieces) each wafer is a single piece. The wafer tumbler lock is often incorrectly referred to as a disc tumbler lock, which uses an entirely different mechanism. The wafer lock is relatively inexpensive to produce and is often used in automobiles and cabinetry.
The disc tumbler lock or Abloy lock is composed of slotted rotating detainer discs.
The lever tumbler lock uses a set of levers to prevent the bolt from moving in the lock. In its simplest form, lifting the tumbler above a certain height will allow the bolt to slide past. Lever locks are commonly recessed inside wooden doors or on some older forms of padlocks, including fire brigade padlocks.
A magnetic keyed lock is a locking mechanism whereby the key utilizes magnets as part of the locking and unlocking mechanism. A magnetic key would use from one to many small magnets oriented so that the North and South poles would equate to a combination to push or pull the lock's internal tumblers thus releasing the lock.
An electronic lock works by means of an electric current and is usually connected to an access control system. In addition to the pin and tumbler used in standard locks, electronic locks connect the bolt or cylinder to a motor within the door using a part called an actuator. Types of electronic locks include the following:
A keycard lock operates with a flat card of similar dimensions as a credit card. In order to open the door, one needs to successfully match the signature within the keycard.
The lock in a typical remote keyless system operates with a smart key radio transmitter. The lock typically accepts a particular valid code only once, and the smart key transmits a different rolling code every time the button is pressed. Generally the car door can be opened with either a valid code by radio transmission, or with a (non-electronic) pin tumbler key. The ignition switch may require a transponder car key to both open a pin tumbler lock and also transmit a valid code by radio transmission.
A smart lock is an electromechanics lock that gets instructions to lock and unlock the door from an authorized device using a cryptographic key and wireless protocol. Smart locks have begun to be used more commonly in residential areas, often controlled with smartphones.[19][20] Smart locks are used in coworking spaces and offices to enable keyless office entry.[21] In addition, electronic locks cannot be picked with conventional tools.
Locksmithing is a traditional trade, and in most countries requires completion of an apprenticeship. The level of formal education required varies from country to country, from no qualifications required at all in the UK,[22] to a simple training certificate awarded by an employer, to a full diploma from an engineering college. Locksmiths may be commercial (working out of a storefront), mobile (working out of a vehicle), institutional, or investigational (forensic locksmiths). They may specialize in one aspect of the skill, such as an automotive lock specialist, a master key system specialist or a safe technician. Many also act as security consultants, but not all security consultants have the skills and knowledge of a locksmith.[citation needed]
Historically, locksmiths constructed or repaired an entire lock, including its constituent parts. The rise of cheap mass production has made this less common; the vast majority of locks are repaired through like-for-like replacements, high-security safes and strongboxes being the most common exception. Many locksmiths also work on any existing door hardware, including door closers, hinges, electric strikes, and frame repairs, or service electronic locks by making keys for transponder-equipped vehicles and implementing access control systems.
Although the fitting and replacement of keys remains an important part of locksmithing, modern locksmiths are primarily involved in the installation of high quality lock-sets and the design, implementation, and management of keying and key control systems. Locksmiths are frequently required to determine the level of risk to an individual or institution and then recommend and implement appropriate combinations of equipment and policies to create a "security layer" that exceeds the reasonable gain of an intruder.[citation needed]
Traditional key cutting is the primary method of key duplication. It is a subtractive process named after the metalworking process of cutting, where a flat blank key is ground down to form the same shape as the template (original) key. The process roughly follows these stages:
Modern key cutting replaces the mechanical key following aspect with a process in which the original key is scanned electronically, processed by software, stored, then used to guide a cutting wheel when a key is produced. The capability to store electronic copies of the key's shape allows for key shapes to be stored for key cutting by any party that has access to the key image.
Different key cutting machines are more or less automated, using different milling or grinding equipment, and follow the design of early 20th century key duplicators.
Key duplication is available in many retail hardware stores and as a service of the specialized locksmith, though the correct key blank may not be available. More recently, online services for duplicating keys have become available.
A keyhole (or keyway) is a hole or aperture (as in a door or lock) for receiving a key.[23] Lock keyway shapes vary widely with lock manufacturer, and many manufacturers have a number of unique profiles requiring a specifically milled key blank to engage the lock's tumblers.
Keys appear in various symbols and coats of arms, the best-known being that of the Holy See:[24] derived from the phrase in Matthew 16:19 which promises Saint Peter, in Roman Catholic tradition the first pope, the Keys of Heaven. But this is by no means the only case.
Some works of art associate keys with the Greek goddess of witchcraft, known as Hecate.[25]
The Palestinian key is the Palestinian collective symbol of their homes lost in the Nakba, when more than half of the population of Mandatory Palestine was expelled or fled violence in 1948 and were subsequently refused the right to return.[26][27][28] Since 2016, a Palestinian restaurant in Doha, Qatar, holds the Guinness World Record for the world's largest key – 2.7 tonnes and 7.8 × 3 meters.[29][30]

Michal concedes the fact that Israelis do the same thing to the memory of the Nakba when saying "it was in 1948, enough talking about the past, let's talk about the future." When the Palestinians come with their keys [the Palestinian symbol of their lost homes], she says, "it's the same thing, it's a memory still burning in the hearts of families
Keys must always be the symbol of the Palestinian "Nakba" – the "disaster" – the final, fateful, terrible last turning in the lock of those front doors as 750,000 Arab men, women and children fled or were thrown out of their homes in what was to become the state of Israel in 1947 and 1948.
The gigantic key, dedicated to all the refugees around the world, was unveiled in a spectacular show at the Katara Amphitheatre last night featuring Palestinian Arab Idol winner Mohammed Assaf. "This key symbol for all the refugees in the world. We want to set a Guinness World Record to say that it is the right of these refugees to return back home. Actually this is linked particularly to Palestinian refugees."... Around 4,000 people filled the Katara Amphitheatre to witness the unveiling of the enormous key and enjoy the concert highlighted by the performance of the young Palestinian singer who is the first United Nations Relief and Works Agency regional youth ambassador for Palestine refugees.
Locksmithing is the work of creating and bypassing locks. Locksmithing is a traditional trade and in many countries requires completion of an apprenticeship. The level of formal education legally required varies by country, ranging from no formal education to a training certificate awarded by an employer, or a full diploma from an engineering college, along with time spent as an apprentice.
A lock is a mechanism that secures buildings, rooms, cabinets, objects, or other storage facilities. A "smith" is a metalworker who shapes metal pieces, often using a forge or mould, into useful objects or to be part of a more complex structure. Thus locksmithing, as its name implies, is the assembly and designing of locks and their respective keys by hand. Most locksmiths use both automatic and manual cutting tools to mold keys, with many of these tools being powered by batteries or mains electricity.
Locks have been constructed for over 2,500 years, initially out of wood and later out of metal.[1] Historically, locksmiths would make the entire lock, working for hours hand cutting screws and doing much file-work. Lock designs became significantly more complicated in the 18th century, and locksmiths often specialized in repairing or designing locks.
Although replacing lost keys for automobiles and homes, as well as rekeying locks for security purposes, remains an important part of locksmithing, a 1976 U.S. Government publication noted that modern locksmiths are primarily involved in installing high-quality lock-sets and managing keying and key control systems.
Most locksmiths also provide electronic lock services, such as programming smart keys for transponder-equipped vehicles and implementing access control systems to protect individuals and assets for large institutions.[2] Many also specialise in other areas such as:
In Australia, prospective locksmiths are required to take a Technical and Further Education (TAFE) course in locksmithing, completion of which leads to issuance of a Level 3 Australian Qualifications Framework certificate, and complete an apprenticeship. They must also pass a criminal records check certifying that they are not currently wanted by the police. Apprenticeships can last one to four years. Course requirements are variable: there is a minimal requirements version that requires fewer total training units, and a fuller version that teaches more advanced skills, but takes more time to complete. Apprenticeship and course availability vary by state or territory.[3]
In Ireland, licensing for locksmiths was introduced in 2016,[4] with locksmiths having to obtain a Private Security Authority license. The Irish Locksmith Organisation has 50 members with ongoing training to ensure all members are up-to-date with knowledge and skills.
In the UK, there is no current government regulation for locksmithing, so effectively anyone can trade and operate as a locksmith with no skill or knowledge of the industry.[5]
Fifteen states in the United States require licensure for locksmiths. Nassau County and New York City in New York State, and Hillsborough County and Miami-Dade County in Florida have their own licensing laws.[6] State and local laws are described in the table below. 15 states require locksmith licensing: Alabama, California, Connecticut, Illinois, Louisiana, Maryland, Nebraska, New Jersey, Nevada, North Carolina, Oklahoma, Oregon, Tennessee, Texas and Virginia.
Locksmiths may be commercial (working out of a storefront), mobile (working out of a vehicle), institutional (employed by an institution) or investigatory (forensic locksmiths) or may specialize in one aspect of the skill, such as an automotive lock specialist, a master key system specialist or a safe technician.[2] Many locksmiths also work as security consultants, but not all security consultants possess locksmithing skills. Locksmiths are frequently certified in specific skill areas or to a level of skill within the trade. This is separate from certificates of completion of training courses. In determining skill levels, certifications from manufacturers or locksmith associations are usually more valid criteria than certificates of completion. Some locksmiths decide to call themselves "Master Locksmiths" whether they are fully trained or not, and some training certificates appear quite authoritative.
The majority of locksmiths also work on any existing door hardware, not just locking mechanisms. This includes door closers, door hinges, electric strikes, frame repairs and other door hardware.
The issue of full disclosure was first raised in the context of locksmithing, in a 19th-century controversy regarding whether weaknesses in lock systems should be kept secret in the locksmithing community, or revealed to the public.
According to A. C. Hobbs:
A commercial, and in some respects a social doubt has been started within the last year or two, whether or not it is right to discuss so openly the security or insecurity of locks. Many well-meaning persons suppose that the discussion respecting the means for baffling the supposed safety of locks offers a premium for dishonesty, by showing others how to be dishonest. This is a fallacy. Rogues are very keen in their profession, and know already much more than we can teach them respecting their several kinds of roguery. Rogues knew a good deal about lock-picking long before locksmiths discussed it among themselves, as they have lately done. If a lock, let it have been made in whatever country, or by whatever maker, is not so inviolable as it has hitherto been deemed to be, surely it is to the interest of honest persons to know this fact, because the dishonest are tolerably certain to apply the knowledge practically; and the spread of the knowledge is necessary to give fair play to those who might suffer by ignorance. It cannot be too earnestly urged that an acquaintance with real facts will, in the end, be better for all parties. Some time ago, when the reading public was alarmed at being told how London milk is adulterated, timid persons deprecated the exposure, on the plea that it would give instructions in the art of adulterating milk; a vain fear, milkmen knew all about it before, whether they practised it or not; and the exposure only taught purchasers the necessity of a little scrutiny and caution, leaving them to obey this necessity or not, as they pleased.
