216 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
station at 11:55 p.m. We came to for the night, moving up off Wash- 
ington street the following morning. We remained at anchor until 
October 25, when, at 11:40 a. m,, we left for the Mare Island navy-yard, 
arriving at 3 p.m. <A general overhauling was commenced imime- 
diately, the work being done, as far as practicable, by our own crew. 
Results of operations on the coasts of Washington, Oregon, and Cali- 
Jornia.—Active operations for the season having been brought to a 
close with the practical completion of the examination of the coasts of 
Washington and Oregon, and a good beginning in northern California, 
it may not be out of place to give here a brief synopsis of the general 
results. A large part of our work has necessarily been hydrographic, 
as there were but few soundings on the charts and none outside of the 
50-fathom curve. Lines of soundings were run off shore at intervals of 
5 to 10 miles, defining the 200-fathom curve from Cape Flattery to the 
vicinity of Cape Mendocino. More detailed examinations were made in 
several localities hereafter mentioned. The fisheries will be prosecuted 
inside of 100 fathoms on the Pacific coast for years to come, and while 
for obvious reasons our investigations extended to the 200-fathom line, 
we will limit the discussion to areas within the former depth. 
The soundings off Cape Flattery were irregular, and suggested the 
existence of submarine ridges lying parallel with the coast; and be- 
tween the cape and Vlattery Rocks, lying about 10 miles from shore, a 
semicircular depression was found having depths from 100 to nearly 
200 fathoms; thence to Yaquina Head the depths increase regularly, 
with the exception of the rocky patch or bank off Grays Harbor and 
Shoalwater Bay, where elevations of a few fathoms were found. Be- 
tween Yaquina Head and Umpquah River lies a submarine plateau, 
triangular in form, with depths less than 100 fathoms, Heceta Bank 
marking its southwestern extremity. Thence to Cape Mendocino the 
soundings were quite regular. 
The 100-fathom curve forms an irregular line, at varying distances 
from shore, as shown by the following table:

‘These cover an area in round numbers of 3,700 square miles on the 
coast of Washington, 4,750 square miles on the Oregon coast, and 1,160 
square miles in northern California, a total of 9,610 square miles.
