268 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
pleasant but warm, the same conditions prevailing until we arrived at 
the Galapagos with one notable exception, March 23, when in 1° 00’ N, 
and 80° 00/ W. we had an overcast rainy day. It was the height of the 
rainy season in the archipelago and showers were of frequent occur- 
rence every day, the sun coming out brightly between them. There 
was more or less rain after leaving the islands to 5° 00’ N. Thence to 
Acapulco, Guaymas, and Cape San Lucas it was invariably bright and 
clear. The mornings were hazy or foggy off the coast of Lower Califor- 
nia, generally clearing between 10 a.m. and meridian. From San Diego 
to the bay of San Francisco it was misty, but not sufficiently thick to 
interfere with navigation. 
The currents from San Francisco to Acapulco were neither strong nor 
constant in direction; the aggregate was 70 miles against us during the 
trip. They were stronger thence to Panama, amounting to about 100 
miles adverse set. From Panama to Cocos Island, Malpelo, and return, 
the general set was south and southeast from 6 to 39 miles per day. 
From Panama toward Cape San Francisco, on the coast of Ecuador, the 
set was southwest to west from 7 to 24 miles per day. 
The Humboldt current was encountered about 2° 00/ N. and 80° 00/ 
W. from 29 to 51 miles a day, setting to the northward and eastward, 
trending more to the eastward as we left the coast, until in 87° 00/ W. 
it was S. 83° E.17 miles in twenty-four hours; thence to the Galapagos 
but little current was noticed. The general set through the archipel- 
ago is to the westward, except from January to April or May, when 
currents are mostly confined to tidal influence. 
A light easterly drift was apparent from the islands to 6° 00/ N.; then 
a westerly set, reaching a maximum of 50 miles per day to about 9° 
00’ N.; thence to Acapulco very light. From the latter port a light 
northwesterly current was felt, increasing as we approached Cape 
Corrientes, and ceasing entirely to the northward of the Tres Marias 
Islands, from which point to Guaymas the drift was light to the east- 
ward. From the latter port to Cape San Lucas and San Diego the cur- 
rents were very light and variable. Thence to San Francisco, where 
the coast was followed closely, the influence of Davidson’s counter- 
current from the southward and eastward was felt. 
The general health of officers and crew was excellent considering the 
rapid and extreme climatic changes they were subjected to. 
Mare Island Navy-yard and San Francisco.—Many of the crew were 
discharged soon after our arrival at Mare Island, their terms of service 
having expired, leaving us with barely force enough to care for the 
vessel. Ensign W. W. Gilmer, U.S. N., was detached on May 8, and 
on the 18th Passed Assistant Engineer J. R. Wilmer, U. 8. N., was 
sent to the naval hospital for treatment for insomnia and nervous 
prostration. On the 28th of the same month telegraphic orders were 
received to commence repairs necessary for the contemplated summer’s 
cruise. It soon became apparent that Mr. Wilmer woul. be unable to
