I shook hands with the _bourgeois_ and delivered the letter; then the boats swung around into the stream and floated away. They had reason for haste, for already the voyage from Fort Laramie had occupied a full month, and the river was growing daily more shallow. Fifty times a day the boats had been aground; indeed, those who navigate the Platte invariably spend half their time upon sand-bars. Two of these boats, the property of private traders, afterward separating from the rest, got hopelessly involved in the shallows, not very far from the Pawnee villages, and were soon surrounded by a swarm of the inhabitants. They carried off everything that they considered valuable, including most of the robes; and amused themselves by tying up the men left on guard, and soundly whipping them with sticks. We encamped that night upon the bank of the river. Among the emigrants there was an overgrown boy, some eighteen years old, with a head as round and about as large as a pumpkin, and fever-and-ague fits had dyed his face of a corresponding color. He wore an old white hat, tied under his chin with a handkerchief; his body was short and stout, but his legs of disproportioned and appalling length. I observed him at sunset breasting the hill with gigantic strides, and standing against the sky on the summit like a colossal pair of tongs. In a moment after, we heard him screaming frantically behind the ridge, and nothing doubting that he was in the clutches of Indians or grizzly bears, some of the party caught up their rifles and ran to the rescue. His outcries, however, proved but an ebullition of joyous excitement; he had chased two little wolf pups to their burrow, and he was on his knees, grubbing away like a dog at the mouth of the hole, to get at them. Before morning he caused more serious disquiet in the camp. It was his turn to hold the middle guard; but no sooner was he called up than he coolly arranged a pair of saddle-bags under a wagon, laid his head upon them, closed his eyes, opened his mouth, and fell asleep. The guard on our side of the camp, thinking it no part of his duty to look after the cattle of the emigrants, contented himself with watching our own horses and mules; the wolves, he said, were unusually noisy; but still no mischief was anticipated, until the sun rose, and not a hoof or horn was in sight! The cattle were gone! While Tom was quietly slumbering, the wolves had driven them away.
