After I had been examined by the doctor and questioned about my religion by the chaplain, I was left to reflect in my cell. I was interrupted in my melancholy train of thought by two convicts who were at work in the hall just outside my cell. I had known them on the outside, and they, taking good care not to be seen by the screws (keepers) tipped me off through my prison door to everything in stir which was necessary for a first timer to know. They told me to keep my mouth shut, to take everything from the screws in silence, and if assigned to a shop to do my work. They told me who the stool-pigeons were, that is to say, the convicts who, in order to curry favor and have an easy time, put the keepers next to what other convicts are doing, and so help to prevent escapes. They tipped me off to those keepers who were hard to get along with, and put me next to the Underground Tunnel, and who were running it. Sing Sing, they said, is the best of the three New York penitentiaries: for the grub is better than at the others, there are more privileges, and, above all, it is nearer New York, so that your friends can visit you more frequently. They gave me a good deal of prison gossip, and told me who among my friends were there, and what their condition of health was. So and so had died or gone home, they said, such and such had been drafted to Auburn or Clinton prisons. If I wanted to communicate with my friends in stir all that was necessary for me to do was to write a few stiffs (letters) and they would be sent by the Underground Tunnel. They asked me about their old pals, hang-outs and girls in New York, and I, in turn gave them a lot of New York gossip. Like all convicts they shed a part of the things they had received from home, gave me canned goods, tobacco and a pipe. It did not take me long to get on to the workings of the prison. I was particularly interested in the Underground Tunnel, for I saw at once its great usefulness. This is the secret system by which contraband articles, such as whiskey, opium and morphine are brought into the prison. When a rogue is persuasive with the coin of the realm he can always find a keeper or two to bring him what he considers the necessaries of life, among which are opium, whiskey and tobacco. If you have a screw "right," you can be well supplied with these little things. To get him "right" it is often necessary to give him a share--about twenty per cent--of the money sent you from home. This system is worked in all the State prisons in New York, and during my first term, or any of the other terms for that matter, I had no difficulty in supplying my growing need for opium.
