COASTS OF WASHINGTON AND OREGON. lie 
In May, 1915, a halibut bank was reported as lying 16 miles nearly 
southwest from the Columbia River Lightship in 80 fathoms. That 
this is a small patch is probable, as soundings made in this locality 
failed to discover any good fishing ground. 
The report of the 1914 investigation says of the area within the 
60-fathom line: — 
On the fine gray sand within the 60-fathom curve, about 9 miles south of Tilla- 
mook Rock, a small patch of shale resembling hard mud was discovered, but an attempt 
to relocate it later proved unsuccessful. Between Cape Falcon and Tillamook Bay 
coarse gray sand was found on a single sounding, in 32 fathoms. From all indications 
it is doubtful if halibut will be found here in paying quantities, although it is the most- 
promising bottom found off Tillamook. * * * The bottom throughout the Tilla- 
mook section seems to be generally unfavorable for halibut, though it supports a great: 
many of the smaller flatfishes and other, at present, less marketable species.@ 
The positions and character of bottom of the most favorable patches 
of bottom are tabulated below. It will be seen that they are all 
small.
