Pillory-Like Barrel

Three men subjected to punishment by the US army are being watched by a guard. The related article describes their predicament as follows:

One wretched delinquent was gratuitously framed in oak, his head being thrust through a hole cut in one end of a barrel, the other end of which had been removed; and the poor fellow “loafed” about in the most disconsolate manner, looking for all the world like a half-hatched chicken. Another defaulter had heavy weights fastened to his wrists, his hands and feet being chained together.
