In traveling with ox teams in the summer season, great benefit will be derived from making early marches; starting with the dawn, and making a "nooning" during the heat of the day, as oxen suffer much from the heat of the sun in midsummer. These noon halts should, if possible, be so arranged as to be near grass and water, where the animals can improve their time in grazing. When it gets cool they may be hitched to the wagons again, and the journey continued in the afternoon. Sixteen or eighteen miles a day may thus be made without injury to the beasts, and longer drives can never be expedient, unless in order to reach grass or water. When the requisites for encamping can not be found at the desired intervals, it is better for the animals to make a very long drive than to encamp without water or grass. The noon halt in such cases may be made without water, and the evening drive lengthened.
WATER.
The scarcity of water upon some of the routes across the plains occasionally exposes the traveler to intense suffering, and renders it a matter of much importance for him to learn the best methods of guarding against the disasters liable to occur to men and animals in the absence of this most necessary element.
In mountainous districts water can generally be found either in springs, the dry beds of streams, or in holes in the rocks, where they are sheltered from rapid evaporation. For example, in the Hueco tanks, thirty miles east of El Paso, New Mexico, upon the Fort Smith road, where there is an immense reservoir in a cave, water can always be found. This reservoir receives the drainage of a mountain.
During a season of the year when there are occasional showers, water will generally be found in low places where there is a substratum of clay, but after the dry season has set in these pools evaporate, and it is necessary to dig wells. The lowest spots should be selected for this purpose when the grass is green and the surface earth moist.
In searching for water along the dry sandy beds of streams, it is well to try the earth with a stick or ramrod, and if this indicates moisture water will generally be obtained by excavation. Streams often sink in light and porous sand, and sometimes make their appearance again lower down, where the bed is more tenacious; but it is a rule with prairie travelers, in searching for water in a sandy country, to ascend the streams, and the nearer their sources are approached the more water will be found in a dry season.
Where it becomes necessary to sink a well in a stream the bed of which is quicksand, a flour-barrel, perforated with small holes, should be used as a curb, to prevent the sand from caving in. The barrel must be forced down as the sand is removed; and when, as is often the case, there is an undercurrent through the sand, the well will be continually filled with water.
There are many indications of water known to old campaigners, although none of them are absolutely infallible. The most certain of them are deep green cottonwood or willow trees growing in depressed localities; also flags, water-rushes, tall green grass, etc.
The fresh tracks and trails of animals converging toward a common centre, and the flight of birds and water-fowl toward the same points, will also lead to water. In a section frequented by deer or mustangs, it may be certain that water is not far distant, as these animals drink daily, and they will not remain long in a locality after the water has dried up. Deer generally go to water during the middle of the day, but birds toward evening.
A supply of drinking water may be obtained during a shower from the drippings of a tent, or by suspending a cloth or blanket by the four corners and hanging a small weight to the centre, so as to allow all the rain to run toward one point, from whence it drops into a vessel beneath. India-rubber, gutta-percha, or painted canvas cloths answer a very good purpose for catching water during a rain, but they should be previously well washed, to prevent them from imparting a bad taste.
