In Western Texas, during the autumn and winter months, storms arise very suddenly, and, when accompanied by a north wind, are very severe upon men and animals; indeed, they are sometimes so terrific as to make it necessary for travelers to hasten to the nearest sheltered place to save the lives of their animals. When these storms come from the north, they are called “northers;” and as, during the winter season, the temperature often undergoes a sudden change of many degrees at the time the storm sets in, the perspiration is checked, and the system receives an instantaneous shock, against which it requires great vital energy to bear up. Men and animals are not, in this mild climate, prepared for these capricious meteoric revolutions, and they not unfrequently perish under their effects.
While passing near the head waters of the Colorado in October, 1849, I left one of my camps at an early hour in the morning under a mild and soft atmosphere, with a gentle breeze from the south, but had marched only a short distance when the wind suddenly whipped around into the north, bringing with it a furious chilling rain, and in a short time the road became so soft and heavy as to make the labor of pulling the wagons over it very exhausting upon the mules, and they came into camp in a profuse sweat, with the rain pouring down in torrents upon them.
They were turned out of harness into the most sheltered place that could be found; but, instead of eating, as was their custom, they turned their heads from the wind, and remained in that position, chilled and trembling, without making the least effort to move. The rain continued with unabated fury during the entire day and night, and on the following morning thirty-five out of one hundred and ten mules had perished, while those remaining could hardly be said to have had a spark of vitality left. They were drawn up with the cold, and could with difficulty walk. Tents and wagon-covers were cut up to protect them, and they were then driven about for some time, until a little vital energy was restored, after which they commenced eating grass, but it was three or four days before they recovered sufficiently to resume the march.
The mistake I made was in driving the mules after the “norther” commenced. Had I gone immediately into camp, before they became heated and wearied, they would probably have eaten the grass, and this, I have no doubt, would have saved them; but as it was, their blood became heated from overwork, and the sudden chill brought on a reaction which proved fatal. If an animal will eat his forage plentifully, there is but little danger of his perishing with cold. This I assert with much confidence, as I once, when traveling with about 1500 horses and mules, encountered the most terrific snow-storm that has been known within the memory of the oldest mountaineers. It commenced on the last day of April, and continued without cessation for sixty consecutive hours. The day had been mild and pleasant; the green grass was about six inches high; the trees had put out their new leaves, and all nature conspired to show that the somber garb of winter had been permanently superseded by the smiling attire of spring. About dark, however, the wind turned into the north; it commenced to snow violently, and increased until it became a frightful tempest, filling the atmosphere with a dense cloud of driving snow, against which it was impossible to ride or walk. Soon after the storm set in, one herd of three hundred horses and mules broke away from the herdsmen who were around them, and, in spite of all their efforts, ran at full speed, directly with the wind and snow, for fifty miles before they stopped.
Three of the herdsmen followed them as far as they were able, but soon became exhausted and lost on the prairie. One of them found his way back to camp in a state of great prostration and suffering. One of the others was found dead, and the third crawling about upon his hands and knees, after the storm ceased.
It happened, fortunately, that I had reserved a quantity of corn to be used in the event of finding a scarcity of grass, and as soon as the ground became covered with snow, so that the animals could not get at the grass, I fed out the corn, which I am induced to believe saved their lives. Indeed, they did not seem to be at all affected by this prolonged and unseasonable tempest. This occurred upon the summit of the elevated ridge dividing the waters of the Arkansas and South Platte Rivers, where storms are said to be of frequent occurrence.
The greater part of the animals that stampeded were recovered after the storm, and, although they had traveled a hundred miles at a very rapid pace, they did not seem to be much affected by it.
