Rules for Exchanging Papers
Any person wishing to exchange papers or periodicals with other prisoners may do so by observing the following rules:
Mark the numbers of the cells to which you wish to send the paper or periodical plainly on the margin thereof and drop it in the exchange box at the foot of the stairs as you go out with your bucket in the morning.
After reading papers sent to you scratch your number out and replace papers in the exchange box the following morning, but do not add any numbers to the list nor erase any but your own.
Weekly and semi-weekly publications circulate ten days from the date of their issue; monthly publications circulate the month of their issue.
Writing on, drawing pictures on, or in any way defacing exchanges is forbidden. Papers must be kept as clean as possible.
