Though Their Appearance Is Very Heavy, They Pass Lightly Over The Most Slippery Turf.

We first stopped at a spring issuing, not from the calcareous rock, but from a layer of quartzose sandstone.

The temperature was 21 degrees, consequently 1.5 degrees less than the spring of Quetepe; and the difference of the level is nearly 220 toises. Wherever the sandstone appears above ground the soil is level, and constitutes as it were small platforms, succeeding each other like steps. To the height of 700 toises, and even beyond, this mountain, like those in its vicinity, is covered only with gramineous plants.* (* The most abundant species are the paspalus; the Andropogon fastigiatum, which forms the genus Diectomis of M. Palissot de Beauvais; and the Panicum olyroides.) The absence of trees is attributed at Cumana to the great elevation of the ground; but a slight reflection on the distribution of plants in the Cordilleras of the torrid zone will lead us to conceive that the summits of New Andalusia are very far from reaching the superior limit of the trees, which in this latitude is at least 1800 toises of absolute height. The smooth turf of the Cocollar begins to appear at 350 toises above the level of the sea, and the traveller may contrive to walk upon this turf till he reaches a thousand toises in height. Farther on, beyond this band covered with gramineous plants, we found, amidst peaks almost inaccessible to man, a small forest of cedrela, javillo,* (* Huras crepitans, of the family of the euphorbias.
