26 USEFUL PLANTS OF GUAM. 
1792, in the roadstead of Umata. Many of the crew were suffer- 
ing from an epidemic caught at Acapuleo. Haenke proceeded to 
Agana and the northern part of the island, Née to the hills near 
Umata, each making collections of plants. Don Antonio Pineda, who 
shortly afterwards lost his life in the Philippines, oceupied himself 
with the geology and zoology of the island. The governor, Lieut. 
Col. Don José 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. Née 
left the Atrevvda on the coast of Chile and proceeded overland, stop- 
ping at Taleahuano, 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. 
Hacnke crossed the Peruvian Andes to Tarma and visited the region 
about Huanuco, at the headwaters of the Rio Huallaga, a tributary of 
the Marafion. 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 be: autifully 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 @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
