In August and September, no perceptible dew falls; but during these months, when vegetation among the small neighbouring dales becomes scanty, the deer often steal in herds to the thickets near the river; and we have stalked them at midnight in the midst of the fields, without discovering a trace of moisture on the alfalfa leaf. The nights are always delightful; and the sky, when it does not rain, is pure, bright, and beautiful. The hills on the eastern side of the valley are clothed with pastures, have perennial springs and wood in their dingles and corries, and are capable of grazing cattle all the year: but opposite to these, on the western side, the hills, like those of the coast, are dull arid masses for nine months in the year, only furnishing a sparse growth of flowering shrubs and weeds on their sides; whilst their elevated tops alone throw forth a denser crop of sweet herbage, on which folds of cattle regale themselves in the months of January, February, and March,—at a season, as we have seen, when the uncultivated heights near the coast are scorched, and stripped of all vegetation except cacti and some bulbous plants. But the plains that spread round the base of the hills and mountains that go to form the Vale of Huanuco, are never allowed to take upon them the withered face of winter. By the aid of rivulets from the mountains, sometimes diverted from their natural channels by art, and carried, by circuitous aqueducts of many miles in extent, the numerous flats among the recesses of the heights and slopes, frequently elevated much above the lower plains, are kept ever verdant and productive, in like manner as the fields and enclosures in the bottom of the vale are fertilized by canals from the river. The best sugar-cane comes to maturity in about eighteen months or two years, and yields several cuttings of after-growth. The lucern or alfalfa, without the aid of top-dressing, gives six crops annually for an indefinite number of years; and in some favoured spots it yields a cutting in six weeks, and therefore gives eight crops yearly. The writer had a plot that yielded, at this rate, alfalfa of about a yard in height, and in good flower. The plantain, both long and short, and the richest tuna, or Indian fig, grow in abundance; the finest pineapples are brought from the neighbouring Montaña, where vegetation is much more rapid and vigorous than in the Vale of Huanuco. In this vale, however, the palta and cheremoya mellow on the branches in their native soil. The maguey, coffee, cotton, and vine, the pomegranate and orange, the citron, lemon, and lime, &c. flourish here; and the meanest villager, as well as the humblest lodger under a cane-roofed shed, inhales with every breath the odours of never-failing blossoms. As the morning sun gilds the high ridges of this happy valley, its inhabitants are animated to the daily labours of the field by the cheerful voice of the prettily-plumaged inmates of their well-shaded bowers.
