26 USEFUL PLANTS OF GUAM. 



1792, in the roadstead of Dmata. Many of the crew were suffer- 

 ing from an epidemic caught at Acapulco. Haenke proceeded to 

 Agafia and the northern pai-t of the island, N^e to the hills near 

 Umata, each making collections of plants. Don Antonio Pineda, who 

 shortly afterwards lost his life in the Philippines, occupied himself 

 with the geology and zoologj^ of the island. The governor, Lieut. 

 Col. Don Jos6 Arlegui, offered them every facility for carrying on 

 their work. Don Juan Ravenet made sketches of a couple of the 

 natives and of a native of the Caroline Islands, between which group 

 and Guam a regular traffic had existed since 1788. The expedition set 

 sail at daylight on the morning of February 24. A few plants were 

 collected on Tinian, one of the northern islands, but the bulk of the 

 collection from the Mariannes was made on the island of Guam. From 

 Guam the expedition sailed for Cape Espiritu Santo, island of Samar, 

 in the Philippine group. From the Philippines it proceeded to Botany 

 Bay, and thence to the Society Islands. Returning to the Peruvian 

 coast, the expedition received news of the French Revolution and of 

 the declaration of war with France. The botanists separated. N^e 

 left the Atrevida on the coast of Chile and proceeded overland, stop- 

 ping at Talcahuano, Concepcion, and Santiago, and thence by way of 

 the Cordillera del Valle to Mendoza and over the pampas to Buenos 

 Ayres. He rejoined the expedition May 10. 



Haenke crossed the Peruvian Andes to Tarma and visited the region 

 about Huanuco, at the headwaters of the Rio Huallaga, a tributary of 

 the Maranon. With the approval of the viceroy of Peru, it was decided 

 that he should proceed across the continent to Buenos Ayres by way of 

 Huancavelica, Ayacucho, Cuzco, and Potosi (situated in what is now 

 Bolivian territory), occupying himself on the way with botany, zoology, 

 and mineralogy; and a soldier named Geronimo Arcangel was detailed 

 to accompany him. Letters were received from him from Cuzco and 

 Arequipa reporting the progress of his explorations and stating that 

 he expected to reach Montevideo the early part of the following year. 

 The expedition, however, was suddenly ordered home on account of 

 the war, and Haenke remained in South America, collecting extensively 

 in the interior of what is now Chile, Peru, and Bolivia. In 1796 he 

 established himself at Cochabamba, a city beautifully situated on the 

 fertile plateau watered by the tributaries of the Rio Grande, now the 

 chief agricultural and industrial center of Bolivia. Here he estab- 

 lished a botanical garden, gave medical assistance to his neighbors, 

 and occupied himself with the study of natural science, making 

 repeated excursions throughout the territory of what is now Chile, 

 Peru, and Bolivia. Alcide d'Orbigny, in his paper on the genus Vic- 

 toria, tells of meeting in his travels in South America with a Spanish 

 missionary. Padre Lacueva, who had accompanied Haenke on one of 

 his expeditions. The padre related an incident which illustrates in a
