There is hardly a tree to be seen except clumps of wood on the mountain-sides miles off,--no vegetation but tufts of coarse grass, among which herds of disconsolate-looking cattle are roaming; the vaqueros, (herdsmen) are cantering about after them on their lean horses, with their lazos hanging in coils on their left arms, and now and then calling to order some refractory beast who tries to get away from the herd, by sending the loop over his horns or letting it fall before him as he runs, and hitching it up with a jerk round his hind legs as he steps within it.
But the poor creatures are too thirsty and dispirited just now to give any sport, and the first touch of the cord is enough to bring them back to their allegiance.
From the decomposed porphyry of the mountains carbonate of soda comes down in solution to the valleys.

Much of this is converted into natron by the organic matter in the soil, and forms a white crust on the earth.

More of the carbonate of soda, mixed in various proportions with common salt, drains continually out in the streams, or filters into the ground and crystallizes there.

This is why there is not a field to be seen, and the land is fit for nothing but pasture.

But when the rains come on in a few months, say our friends in the diligence, this dismal waste will be a luxuriant prairie, and the cattle will be here by thousands, for most of them are dispersed now in the lower regions of the tierra templada where grass and water are to be had.
My companion and I climb upon the top of the diligence to spy out the land.
