Plate 3'1 



The daily direction of the winds is indicated on PI. S'^, the arrows show- 

 ing the direction, and the number of barbs the strength of the wind accord- 

 ing to the Beaufort scale. 



From Panama to the Galapagos we encountered during the first days 

 of November southwesterly winds for the first half of the distance, and then 

 southeasterly winds as far as the islands, and the same southeasterly trades 

 from the Galapagos to Aguja Point, and in our line to the southwest of the 

 Point as well as from that point to Callao, the southeasterly trades extend- 

 ing on the line, Callao to Easter Island, to about 17" S. latitude and 85° W. 

 longitude. From that point to Sala y Gomez the winds were from the north- 

 east. At Easter Island we found them variable during our stay during the 

 middle of December. 



From Easter Island to latitude 19" S. we encountered westerly and north- 

 easterly winds ; from that point northward to the Galapagos we met south- 

 easterly and easterly trades. From the Galapagos towards Manga Reva the 

 same easterly and southeasterly trades flanked us as far as 10' S. latitude. 

 The winds then became northeast almost to Manga Reva, where they were 

 southwesterly. 



From Manga Reva towards Acapulco we encountered, north of 20' S.' lati- 

 tude, northerly winds for about 500 miles. The winds then became easterly 

 or southeasterly to nearly 3' N., where we struck strong northeast trades to 

 within 250 miles off Acapulco, where we met light northwesterly winds. 



From Panama to the Galapagos, from the Galapagos to Aguja Point, on 

 the line to the southwest of this point, and thence to Callao, and from Callao 

 about a third of the distance to Easter Island, the set was usually in the 

 direction of the wind. Though near the shore the current was in a north- 

 easterly direction, and from latitude 20 S. as far as Sala y Gomez the set 

 was strong in a northeasterly direction. 



On the line from Easter Island to the Galapagos there was a strong 

 southeasterly set as far as latitude 15' S. Then the set was in the direc- 

 tion of the wind to the northwest as far as the Galapagos. It became 

 variable in the vicinity of the Galapagos. 



From the Galapagos half-way to Manga Reva the set was in the direc- 

 tion of the southeast trades to the northwest. The remaining distance
