becomes more rolling except immediately along the Deseado 

 River. This stream is small and winding, and filled with 

 numerous snags so that progress by canoe was exceedingly 

 slow, the boatmen often being compelled to get into the water 

 and push or drag the canoe over logs and shallows. In the 

 character of the vegetation lining its banks this stream does 

 not differ materially from the La Juana, already described. 

 Its banks are rather high and mostly nearly vertical, and its 

 bottom is sandy or muddy. 



For some distance beyond Camp Menocal the character of 

 the coimtr}^ remains unchanged, but as the Divide is ap- 

 proached the country becomes much rougher, the paths 

 become more nearly vertical, and travel is more difficult. 

 Near the Divide the Deseado, here scarcely more than a large 

 brook, dashes over ledges of rock forming two beautiful 

 waterfallsj the Saltos Louisa and the Saltos Laura. Between 

 and below these falls the stream flows through a deep canon 

 or ravine whose sides are covered with a splendid carpet of 

 luxuriant vegetation, the whole forming a charming picture. 

 This valley is to form a portion of the proposed canal, and it 

 is indeed a pity to ruin this beautiful picture even b}^ such a 

 magnificent undertaking. The return to Camp Menocal was 

 made in the afternoon of the same day through a heavy rain 

 which equally soaked the clothing and dampened the spirits 

 of the party. The night was again spent at Camp pylenocal 

 and on the following morning the trip to Camp Seven was 

 made on foot by a shorter route across country; the return 

 to Grevtown was made bv hand-car. 



Notwithstanding the heavy rams the trip was very profita- 

 ble. As it was evident that it would be impossible to care for 

 much material which required pressing, but few Phanero- 

 gams were collected, namely about 20 specie's, the principal 

 attention being given to Ferns of which about 30 species 

 were added to the list. The pressed specimens which were 

 collected at Gre3"town and vicinity were subsequently dried 

 on board the steamer which carried the party from Bluefields
