In Boston, when we host our French guests, they are delighted by the squirrels running around Boston Commons. Here there are no squirrels but in the morning and late afternoon, the monkeys put on a show. Like squirrels, they scurry and jump, but their jumping leave the squirrel displays in the dust. They love to swing from tree to tree. They swing out on a hanging branch and swing in a long arc to the next tree. Then three or four of their friends follow. They balance on a fence, keeping upright by sheer speed and the length of their tales. Occasionally they fall but it doesn't seem to matter. Up they go again, chasing and climbing till they tire and find a spot high up to rest.
