They call it "cinching" in prison lingo.

On occasion, when the guards are cruel and vindictive, or when the command has come down from above, in order to insure the severity of the lacing the guards press with their feet into the man's back as they draw the lacing tight.
Have you ever laced your shoe too tightly, and, after half an hour, experienced that excruciating pain across the instep of the obstructed circulation?
And do you remember that after a few minutes of such pain you simply could not walk another step and had to untie the shoe-lace and ease the pressure?
Very well.

Then try to imagine your whole body so laced, only much more tightly, and that the squeeze, instead of being merely on the instep of one foot, is on your entire trunk, compressing to the seeming of death your heart, your lungs, and all the rest of your vital and essential organs.
I remember the first time they gave me the jacket down in the dungeons.
It was at the beginning of my incorrigibility, shortly after my entrance to prison, when I was weaving my loom-task of a hundred yards a day in the jute-mill and finishing two hours ahead of the average day.

Yes, and my jute-sacking was far above the average demanded.

I was sent to the jacket that first time, according to the prison books, because of "skips" and "breaks" in the cloth, in short, because my work was defective.
