driven it to the southward as described; th< present fishing station is located on the 
beach at the exit. Considerable of the volume of the stream must seep out through 
the shingle, for at its visible exit it has shrunk to barely 10 feet in width, 10 or 12 
inches in depth, with a velocity of 11 knots an hour. In the lagoon the bottom is of 
sand and shingle. The banks of the stream, except the lagoon, are steep inclines 
covered with a dense growth of rank grasses and moss. Tide water rarely backs up 
into the lagoon; during heavy westerly storms the seas break over the shingle barrier. 
The water is rather discolored, this being particularly noticeable below the lagoon. 
Red salmon were running in numbers up the stream at the time of our visit, 
though very few were observed entering the lake during the short time spent at the 
outlet. Large schools were seen in the lagoon, and it is possible that the fish school 
there before finally ascending to the lake. No dog salmon or humpbacks were 
noticed, though both species are said to run at times. The course of the stream was 
followed from the lake outlet to the exit, except a short distance above the. lagoon, 
and it is not believed there were any barricades at that time; no signs or indications 
of them were discovered, and no well-worn trails were seen anywhere beyond the 
lagoon. It is not believed, therefore, that salmon have this season been taken in any 
other than the salt water of the bay. The entrance of fish could be stopped in a 
moment by merely laying a small piece of web across the beach at the stream exit, 
and probably this has been done when fish were scarce. Immense numbers were 
jumping about the bay in all directions on the afternoon of August 2, but no fishing 
was going on, as the crew stationed there had already taken their daily quota. 
For want of proper facilities the lake could only be examined from a point near 
the outlet. Its axis is about east by north and west by south (magnetic), a mile in 
greatest length, by three-fourths of a mile average width. The shores are grassy on 
all sides, and the beaches of gravel, sand, and shingle, with rocky ledges and outcrops 
in places, shelve gently into deeper water. The lake did not have the appearance of 
more than moderate depth. The other lakes shown on the sketch were not seen bv the 
party at this time, but had been previously sketched from the mountains northwest of 
Snug Harbor. Very few dead salmon were seen along the banks of the stream, and 
none on the beaches of the lakes. No entering streams or feeders were to lie seen. 
It did not appear that the locality is well suited for hatchery purposes; the lake 
water is far from pure and would require careful filtering, and a supply, as far as 
could be seen, is only to be had by pumping. 
Horse Marine Lagoon , at the eastern end of the eastern arm of Olga Bay, is sepa- 
rated from the latter by a narrow grass-covered shingle spit. The spit extends north 
from the southern shore of the bay, leaving a narrow opening, the exit of the lagoon, 
between its northern end and the opposite shore. The lagoon is about five-eighths 
mile in length, east-northeast and west-southwest (magnetic), in the general direction 
of the short valley into which it makes; the width is about one-third its length. It 
is shallow, with bottom of sand, gravel, shells, and shingle, and is badly choked by 
a thick matted growth of coarse eelgrass; the shores are indented with several small 
sloughs and coves. The banks were everywhere covered (August 2) with a dense 
growth of coarse grasses and rank weeds, wild flowers, and berry shrubs. The small 
tides of the outer bay are felt to the head of the lagoon, but to no great extent; very
