186 NOCTURNAL HOWLINGS. 



sixteen huts constructed of palm-leaves, and inhab- 

 ited by a tribe of the Guamoes. These Christians 

 were unable to furnish them with the provisions 

 which they wanted, but hospitably offered them dried 

 fish and water. The night was spent on a bare and 

 very extensive beach. The forest being impenetra- 

 ble, they had great difficulty in obtaining dry wood 

 to light fires for the purpose of keeping off the wild 

 beasts. But the night was calm, with beautiful 

 moonlight. Finding no tree on the banks, they stuck

 The Indians distinguished the cries of sapajous, alou-

On the 2d April they set sail before sunrise. The 

 river was ploughed by porpoises, and the shore 

 crowded with aquatic birds ; while some of the latter,

 count of the large trees which remain obliquely fixed 

 in the mud, and the canoe touched several times. 

 Near the island of Carizales, they saw enormous 

 trunks covered with plotuses or darters, and below 

 it observed a diminution of the waters of the river, 

 owing to infiltration and evaporation. Near the 

 Vuelta de Basilio, where they landed to gather
