The More Space The Association Occupies The More Resistance Do The Social Plants Oppose To The Labourer.

With this general cause others are combined in the Llanos of Venezuela; namely the action of the small grasses

Which impoverish the soil; the total absence of trees and brushwood; the sandy winds, the heat of which is increased by contact with a surface absorbing the rays of the sun during twelve hours, and unshaded except by the stalks of the aristides, chanchuses, and paspalums. The progress observable on the vegetation of large trees and the cultivation of dicotyledonous plants in the vicinity of towns, (for instance around Calabozo and Pao) prove what may be gained upon the Llano by attacking it in small portions, enclosing it by degrees, and dividing it by coppices and canals of irrigation. Possibly the influence of the winds which render the soil sterile might be diminished by sowing on a large scale, for example, over fifteen or twenty acres, the seeds of the psidium, the croton, the cassia, or the tamarind, which prefer dry, open spots. I am far from believing that the savannahs will ever disappear entirely; or that the Llanos, so useful for pasturage and the trade in cattle, will ever be cultivated like the valleys of Aragua or other parts near the coast of Caracas and Cumana: but I am persuaded that in the lapse of ages a considerable portion of these plains, under a government favourable to industry, will lose the wild aspect which has characterized them since the first conquest by Europeans.
