There are places where the jimmy is absolutely indispensable to the burglar. Front doors, which a house proprietor usually has doubly bolted and barred and supplied with improved locks, are the last apertures in the world a night marauder would seek to enter.

It must be an amusing thing to the burglar, after noting the precautions taken to prevent his entrance by the street door, when he has walked through the skylight on the roof without the slightest resistance, or dropped through the coal-hole leading to the cellar from the sidewalk, to find that no doors bar his passage from there to the rooms above.

Those are the popular ways of getting into many banks and business houses. The basement door, at the rear, if there is one, is another. In such case the jimmy is the magic wand that opens the way. It is more useful to the burglar than any half dozen of his other implements, and is the first thing he purchases when getting an outfit.

How do safe burglars get their tools? Why, every man of any account in that line has what he calls "his man," who is a practical mechanic, and makes everything in the shape of jimmies, punches, etc., that the burglar uses. A safe blower's outfit consists of many curious tools, some of them being of special design for some particular class of work of which the owner is the originator. Scarcely any two men work alike, and some of the clever ones invent instruments to do a certain part of their work. When a well-known notorious crook was arrested several years ago in his room, the officers found one of the finest kits of burglars' tools that was ever brought into police headquarters. Talk about ingenuity—if that man had applied but one-third of the intelligence to a legitimate business that he had spent in devising tools for robbery, he would have been a millionaire today.

Twenty years ago when burglars started out to rob a safe they filled a carpet sack with highly tempered drills, copper sledges, sectional jimmies, dark lanterns, powder and a fuse. On the way they stole a horse and wagon, filling the latter with the greater portion of the tools of a country blacksmith shop. They would work on the safe from four to six hours, and finally blow it open with a fine grade of ducking powder. Usually the shock would break all the glass in the building, arouse the town, and the burglars would often have to fight for their lives. In those days the men had to be big and powerful, because the work was extremely laborious. If the burglar was an ex-prize fighter or noted tough, so much the better, for he could make a desperate resistance in case he was caught in the act, or immediately after it.

With the modern safe burglar it is almost totally different. Although much more skillful and successful than his predecessor, he is more conservative. He seldom runs his own head into danger, and therefore seldom endangers the head of a law-abiding citizen by permitting his head to come into contact with him or the job while it is under way. Every precaution is taken against being surprised, and it is seldom the robbery is discovered until the cashier's appearance the next morning. The modern safe burglar is an exceedingly keen, intelligent man. He can open a safe having all modern improvements in from ten minutes to two hours without the aid of explosives and by only slightly defacing the safe. Sometimes he leaves scarcely a mark.

A first-class modern safe, whether large or small, generally has double outside and inside doors, with a steel chest in the bottom, forming really a safe within a safe, the inside being the stronger. The outside door is usually either "stuffed" or "skeleton." The inside one is made of eight or nine sheets, of different temper, of the finest steel. These sheets are bolted together with conical bolts having left-hand threads, after which the heads of the bolts are cut off, leaving what is virtually a solid piece of steel, which no drill can penetrate. The best locks are of the combination type, with time lock attachment. In many cities and town safes containing the valuables have an electric alarm attached. Any tampering with it will communicate the fact to the owners or the safe's guardian, which in cities is either an electric protective bureau or a central police station. A recent invention in France is a photographic attachment. As soon as the safe is touched this device will light an electric lamp, photograph the intruder and give the alarm at the electric protective company's office. As a consequence safe-breaking is going out of date in France, as the cleverest criminals have so far failed to find a way to circumvent the camera.

The first thing considered by a gang of the finest experts is a desirable bank's location and the chances for getting safely away with the plunder. Every transportation facility is carefully considered. As the work is almost invariably done at the season of the year when wagon roads are impassible, railroad time tables are carefully considered. In these days of the telegraph and telephone the gang must be under cover in a large city or concealed with friends by the time the crime is discovered, which, at the utmost, is about six hours after the crime has been committed.

From November 1 to March 1 is the safe burglar's harvest time, because then the nights are longest and the chances of detection less, as fewer people are on the streets and houses adjoining, being tightly closed to exclude the cold, exclude noises also. A man can, furthermore, carry tools in an overcoat without attracting attention, that he could not wear with a summer suit. The remainder of the year is spent in "marking" the most desirable banks for future operations. Four men, who compose the ordinary safe mob, will put up from thirty to forty "jobs" for a winter's work, allowing for all contingencies. From six to ten of these will be carried out. A bank safe will be broken into in a small town in Maine, and in ten days the gang will be operating in Texas.
