We learn from the Colonies that a monkey signalman manages the railway traffic at Witenhage, South Africa. The human signalman has had the misfortune to lose both his legs, and has trained a baboon to discharge his duties. Jacky pushes his master about on a trolly, and, under his directions, works the lever to set the signals with a most ludicrous imitation of humanity. He puts down the lever, looks round to see that the correct signal is up, and then gravely watches the approaching train, his master being at hand to correct any mistake.
