favourite fodder for the horses in the Mexican highlands, and in the hotter districts the leaves of young Indian corn. Oats are to be seen growing by chance among other grain, but they are never cultivated. Though wheat is so much grown upon the plains, it is not because the soil and climate are more favourable than elsewhere for such culture. In the plains of Toluca and Tenancingo the yield of wheat is less than the average of the Republic, which is from 25- to 30-fold, and in the cloudy valleys we passed through near Orizaba it is much greater. Labour is tolerably cheap and plentiful here, however; and then each large town must draw its supplies of grain from the neighbouring districts, for, in a country where it pays to carry goods on mules’ backs, it is clear that grain cannot be carried far to market.
In the question of the population of Mexico, one begins to speculate why—in a country with a splendid climate, a fertile soil, and almost unlimited space to spread in, the inhabitants do not increase one-half so fast as in England, and about one-sixth as fast as their neighbours of the United States. One of the most important causes which tend to bring about this state of things is the impossibility of conveying grain to any distance, except by doubling and trebling its price. The disastrous effects of a failure of the crop in one district cannot be remedied by a plentiful harvest fifty miles off; for the peasants, already ruined by the loss of their own harvest, can find neither money nor credit to buy food brought from a distance at so great an expense. Next year may be fruitful again, but numbers die in the interval, and the constitutions of a great proportion of the children never recover the effects of that one year’s famine.
We left the regular road and struck up still higher into the hills, riding amongst winding roads with forest above and below us, and great orchids of the most brilliant colours, blue, white, and crimson, shining among the branches of the oak-trees. The boughs were often breaking down with the bulbs of such epiphytes; but as yet it was early in the
