April 28th. It poured with rain as soon as the sun set and we were worried about the damage to our collections. The poor missionary suffered one of his fever attacks and begged us to leave before midnight. After passing the Guarinuma rapids the Indians pointed out the ruins of the Mendaxari mission, abandoned some time back. On the east bank of the river, near the little rock of Kemarumo in the middle of Indian plantations, we saw a gigantic ceiba (the Bombax ceiba). We landed to measure it; it was some 120 feet high, with a diameter of 14 or 15 feet.

The recommendations from the Madrid Court assured us that we were always well received in all the Spanish possessions. The Captain-General immediately gave us permission to visit the island. Colonel Armiaga, in command of an infantry regiment, warmly welcomed us to his house. We did not tire of admiring the banana trees, the papaw trees, the Poinciana pulcherrima and other plants usually seen only in greenhouses.

We re-embarked at sunset and set sail, but the breeze was too weak toenable us to follow our route to Tenerife. The sea was calm; a reddish hazecovered the horizon, seeming to magnify everything. In such solitudes, by so many uninhabited islands, we savored the view of such a grandiose and wild nature. Theblack mountains of Graciosa had perpendicular walls some 500 to 600 feet high. Their shadows, projected across the sea, made thescene gloomy. The basalt rocks stuck out of the water like the ruins of avast building. Their existence reminded us of that bygone age whenunderwater volcanoes gave birth to new islands, or destroyed continents. Everything around us spoke of destructionand sterility; yet beyond this scene the coast of Lanzarote seemed morefriendly. In a narrow gorge, between two hills crowned with scatteredtrees, you could see some cultivated land. The last rays of sun lit up the ripe corn, ready for harvesting. Even thedesert is animated when you see some trace of man's work in it.

We suffered much from the heat, increased by the reverberation from the dry, dusty ground. However, the excessive effect of the sun held no harmful consequences for us. At La Guaira sunstroke and its effects on the brain are feared, especially when yellow fever is beginning to appear. One day I was on the roof of our house observing the meridian point and the temperature difference between the sun and shade when a man came running towards me and begged me to take a drink he had brought along with him. He was a doctor who had been watching me for half an hour out in the sun from his window, without a hat on my head, exposed to the sun's rays. He assured me that coming from northern climes such imprudence would undoubtedly lead that night to an attack of yellow fever if I did not take his medicine. His prediction, however seriously argued, did not alarm me as I had had plenty of time to get acclimatized. But how could l refuse his argument when he was so polite and caring? I swallowed his potion, and the doctor must now have included me in the list of people he had saved from fever that year. (67)
