The most difficult branch of the "profession" for the young thief to learn is "counter creeping." To enter a shop on your hands and knees, crawl round behind the counter, and secure the till unnoticed by the shopkeeper requires the most skilful use, not only of the hands, but of the knees. The slightest sound as you crawl along the floor might attract attention. Yet, in spite of its difficulties, this branch of the business has many apprentices, who practise in a room in which an imitation counter is fitted up.

The "till sneak" occasionally acts with an accomplice, sometimes with two. When the favourable shop has been fixed upon, the habits of its owners studied, and the propitious moment chosen, one of the confederates enters as a pretended customer and engages the attention of the shopkeeper—frequently a woman. Another confederate keeps observation outside, and is ready to facilitate the exit of his "pals." The trained till thief creeps in and secures the haul noiselessly.

It often happens that the shopkeeper does not discover the loss until another customer has been served, and he or she goes to the till to put money in it and finds it empty.

But with all their cleverness, with all the risks they run in following their dishonest occupations, these professional thieves seem to make a very poor living.

If you would see how they live, let us go boldly into one of the criminal areas and enter the houses.

Here is the most notorious criminal street in London. The inhabitants are frankly thieves and of a very rough class. In the centre of the street is a lodging-house in which some two hundred thieves are accommodated nightly, and there is hardly a house from end to end in which the weekly rent is gained by honest industry.

Look at this "notice" chalked up in big letters on a wall: "Coppers wanted. Three killed last night."

That is a playful exaggeration. A policeman killed in this street a month or two ago, but only one. The whistle of a hooligan captain sounded, and scores of young roughs poured out of the houses to obey the summons. A "nark," or a lad who was suspected of "marking"—i.e. betraying a comrade by giving information to the police—had ventured into the neighbourhood, and the gang were called forth to administer lynch law. There was a big fight, for the suspected "nark" had pals too. In the course of the combat an unfortunate policeman so far forgot the first law of nature as to enter the street with a view of restoring order. He was so badly knocked about and injured that he died shortly afterwards.

If you enter the houses, which are mostly let at 12s. 6d. a week and taken by one person, who lets off the rooms and lives rent free in the process, you will find the most terrible squalor and apparent misery.

Most of the families live in one room. Occasionally, when one of the girls is old enough to do factory-work and bring home a regular wage, the luxury of two rooms is indulged in.
