"The business is entirely in the hands of the natives or the half-breeds, as no genuine Spaniard would consider it high enough for his dignity. Some of the arrieros possess many mules, but the most of them have but half a dozen, or perhaps ten or twelve, and travel personally with their trains. The _peons_, or servants of the arrieros, are likewise of the native race, and accustomed all their lives to hardship and toil. Their wants are few, as they live on food that can be easily transported; their general outfit for the road is a cotton shirt and trousers, a straw hat, and a _poncho_, or blanket with a hole in the centre, through which the head is thrust. This poncho is striped with gay colors, and is very often quite attractive to the eye. Each arriero or peon carries his own food, which usually consists of a few red peppers, a bag of parched corn, and another of barley meal. With this slender nourishment they pass their lives on the rough roads among the mountains, and immediately on arriving from one hard journey they are ready for another. [Illustration: IN HOLIDAY COSTUME.] "We were surrounded by half a dozen arrieros at once, and there was no difficulty in making a bargain, as several trains had just arrived from the mountains, and were anxious to return. We engaged five mules, three for ourselves, and two for our baggage; the owners endeavored to convince us that another animal was needed for the baggage, but as we had less than three hundred pounds of it altogether, we were not to be convinced. Our arriero promised to be ready to start early the next morning, but it was nearly noon before we got away. We tried to hurry him, but it was of no use; he was anxious enough before making the bargain, but now that it was settled, and competition was out of the way, his anxiety had ceased. "The baggage was piled on the mules that were to carry it, and when all was ready we mounted our saddle animals. They were not very prepossessing in appearance, and looked as though the mountain journey would be too much for them, but they were the best in the train, and we concluded to be content with the situation. Mules are considered better than horses for this sort of work, as they are surer in their footing, and will venture in places where a horse refuses to go. Bulls and donkeys are also used here for carrying burdens along the mountain roads, but they are not equal to mules. [Illustration: A PACK-TRAIN UNDER WAY.]
