western channel, are the remains of barricades. Trees have been felled across these 
branches and were still in position, but the split rails were washed away. A gravel 
ridge was noted on the upstream side, where the rails had lodged in the bed. A large 
number of humpbacks and dog salmon were seen spawning in the lower courses, 
growing less in number as the higher portion of the stream was reached. It was too 
early for cohoes. 
This is a very large stream, flowing considerable water, and carries a heavy run 
of all species of salmon common to the district, except redlish, of which, it is said, 
there are none in the North Bay of Pillars. This is a noted locality for cohoes. 
Fifty thousand to 60,000 of this species, it is said, may be taken around the mouth 
and the head of the bay, as well as about 100,000 humpbacks. Dog salmon are also 
abundant. These cohoes are large and, for commercial purposes, run from Septem- 
ber ] to October 7, then in diminishing numbers until November. The humpbacks 
run from the middle of July to the end of August and the dog salmon throughout the 
season, but mostly during the humpback run. 
There are no stream records available. Besides those salted, cannery steamers 
sometimes fish here for a few days, and what can be done during that time is indi- 
cated by the following record from the books of the Baranoff Packing Company: 
In 1892, 1,522 cohoes, September 8 to 15; in 1895, 2,836 cohoes, September 20 to 
22; in 1896, 3,607 cohoes, September 15 to 19; in 1897, 957 cohoes, September 19. 
PILLAR BAY STREAM, No. 2. 
This stream, next east of the Pillar Bay Stream and three-fourths of a mile from 
it, was also examined by Ensign Kempff for a distance of 8 miles and no lake found. 
From the most distant point reached, which is 305 feet above sea level, the stream 
flows to the northwest for 3 miles and then turns in a general southerh T direction for 
5 miles. The water is clear and clean and flows over a rocky bottom, interspersed 
with patches of gravel and shoals, over which fish were spawning. There are 
numerous rapids, and at a point 1 miles from the mouth there is a drop of 30 feet 
in the main fall, besides several smaller steps. The banks are heavily wooded, 
precipitous, and broken into bluffs in the vicinity of the falls and at a point about 1 
mile above the mouth. Tide water extends a mile from the mouth, where the stream 
is 30 feet wide, 18 inches deep, and runs with a strong current. The temperature, 
taken each mile, was 51° F. (August 30). Five small tributaries were noticed in the 
distance — two entering from the west and three from the east — and were examined. 
There were no natural or artificial obstructions below the falls. A large number of 
humpbacks and dog salmon were seen spawning in the lower courses of the stream, 
diminishing in numbers as far as the falls, but none above it. 
The fishing is carried on around the head of the bay. The values given under 
the Pillar Bay Stream include the one just described, though it furnished but a small 
part of the total. 
MANTLE SALTERIES. 
There are two salteries operated by Mr. Jack Mantle; one on the eastern bank 
of the arm and near the mouth of the Point Ellis Stream, where there are 10 tanks 
each of 20 barrels capacity, and one on the western shore of the inner North Bay of
