During this process, Grandpa the monkey was permitted to come out of the cabin and entertain the crowd of onlookers with his antics, which he did to perfection, as he had done at other stops.  To the ivory ring about his slender little waist, Paul always fastened a long thin rope, which he had bought in Para, when he let Grandpa out.  This leash prevented him from wandering off, something nearly all unfettered monkeys will do if not watched very closely by their masters.  Almost any place seems to be home to a monkey, and almost any man seems to suit him for a temporary master.
