(f)When the warders and convict-officers are posted to the several gangs in the morning; the names of the prisoners composing each gang shall be called from the gang-book in the presence of the officer about to take charge, who shall verify the total by counting them. The officer's name shall then be recorded in the gang-book and his receipt taken. Every long termed and dangerous prisoner should be specially pointed out to the warder about to take charge of him, so that a particular watch may be kept on him. At every change of guard the number of prisoners in each gang shall be counted, and in the case of gangs outside the jail, the names of the prisoners composing each gang shall be called over. In large jails there should be several gang-books, so that the rolls may be called simultaneously to save time. Vernacular convict- writers may, when necessary, be employed to assist in writing up the gang- books.
