16 SURVEY OF FISHING GROUNDS, 1915. 
and red rock cod numerous, 29 being taken on the trawl. Dogfish 
and blue sharks occurred in moderate numbers. 
Set 11.—On July 21, W. by S. 4 W. 21.8 miles from Destruction 
Island, a bottom of gravel, gray and black sand, shells, and green 
mud were found. The next day the spot was located and a trial 
made in 101 fathoms. Eight halibut were taken, two being males 
weighing 46 and 26 pounds. As in sets 1 and 111 the largest halibut 
proved to be males, although in the four sets 14 females and 4 males 
were taken. Black cod were exceptionally numerous and of a large 
size, 71 being caught, 1 of which weighed 36 pounds. In this set 20 
dogfish and 19 blue sharks were secured. A small stone covered 
with worm casts, sponges, etc., was brought up on the trawl. 
Set I1I.—Too late to make a set on July 23, a patch of good halibut 
bottom was found in 99 to 124 fathoms W. by S. 4 W. 31 miles from 
Grays Harbor Light. On July 24 a set was made on the edge of this 
patch in 98 fathoms where the sounding lead showed as fine green 
sand. The offshore ends of the two trawls evidently fell on a gravel 
bottom, because both of them brought up small stones the size of 
ducks’ eggs and covered with organic remains. But 2 halibut were 
obtained on this set, 1 on each trawl, weighing 22 and 24 pounds, 
respectively, the latter being a male. A number of other fish, 21 
black cod (9 young), 7 blue sharks, 2 dogfish, 3 arrow-toothed halibut, 
and 1 flounder, were caught. 
Set IV.—On July 22 good bottom of gravel and coarse sand, 
together with a little green mud, was found on the southern ridge of 
the deep channel which separates Flattery Bank from Cape Flattery. 
A set was made on this ridge on July 27, SW. by W. 20.7 miles from. 
Umatilla Lightship. Three halibut were secured weighing 94, 55, 
and 30 pounds, all females. About 150 black cod weighing 40 to 50 
pounds, 10 dogfish, and 8 blue sharks were caught. The black cod, 
according to the fishermen, were the largest and most numerous they 
had ever seen. Only one trawl could be hauled in; the other was 
bitten off at both ends by sharks as soon as the haul in was started. 
Many of the black cod were cut in two by the sharks, numbers of 
which continually swam around the ship at the surface of the water. 
From the number of birds (‘black hags,”’ gulls, ete.), whales, and 
sharks, the proximity of good feeding grounds was plainly evident.
