At Fray Cristoval Mr. Ruxton came upon the river Del Norte, and thence pushed along its banks to the ruins of Valverde, where, encamped in the shade of noble trees, he found a trading caravan and a United States surveying party, under the command of a Lieutenant Abert. The traders’ waggons were drawn up so as to form a corral, or square—a laager, as the Boers of South Africa call it—constituting a truly formidable encampment, which, lined with the fire of some hundred rifles, could defy the attacks of Indians or Mexicans. “Scattered about,” says Mr. Ruxton, “were tents and shanties of logs and branches of every conceivable form, round which lounged wild-looking Missourians; some looking at the camp-fires, some cleaning their rifles or firing at targets—‘blazes’ cut in the trees—with a bull’s-eye made with wet powder on the white bark. From morning till night the camp resounded with the popping of rifles, firing at marks for prizes of tobacco, or at any living creature which presented itself. The oxen, horses, and mules were sent out at daylight to pasture on the grass of the prairie, and at sunset made their appearance, driven in by the Mexican herders, and were secured for the night in the corrals. My own animals roamed at will, but every evening came to the river to drink, and made their way to my camp, where they would frequently stay round the fire all night. They never required herding, for they made their appearance as regularly as the day closed, and would come to my whistle whenever I required my hunting mule.”
