dog salmon, Oncorhynchus keta. This year they appeared as early as 
March 4th, when a few straggling schools of from 8 or 10 to 20 or 30 
appeared in the shallow water near the shore. These were 30-35 mm. 
long, and several retained part of the yolk, although already they had the 
characteristic parr-marks in the majority of cases. Some of them, even 
when much older than this, or perhaps rather when they are much older, 
have no sign of the bars, so that they look very much like humpbacks. 
It seems scarcely possible that they are anything but dog salmon, as 
they are found in the same school with the barred forms, although at 
certain times they seem to predominate. 
After watching these fry for some time, the wonder that they grow 
so rapidly after they reach sea water gradually disappears, as it would 
be hard to imagine a more active mass of condensed hunger than each of 
these appears to be. Watch them at any time during the day and the 
restless movement goes on. A snap is made at a desirable morsel here 
and another there, with no intermission of any length. At night when 
other sounds are stilled, the continuous jumping and splashing makes 
a ripple like that of a brook bubbling over a pebbly bed, so that it can 
be heard distinctly many rods away from the shore. Looking down 
over the water one sees them pass on in their illumined way as they 
disturb the various phosphorescent forms, some of which become phos- 
phorescent no more. Occasionally when a large fish comes up with a 
splash to devour some of them, those fortunate enough to escape the 
cruel jaws, make such a speedy departure from the spot that the phos- 
phorescence becomes more noticeable, looking like a meteoric shower 
in miniature. 
Catch them when you will, their stomachs are gorged with food, and 
one would think that their digestive systems would have to work over- 
time to get everything assimilated. They are not particular as to their 
diet. Apparently anything that can be swallowed goes. If one edible 
species is abundant that serves very well; if there is great variety that 
seems to do just as well. On one occasion I found them eating nothing 
but dipterous insects, at another nothing but barnacle larve, at another 
nothing but appendicularia. At one time they were filled with clado- 
cera and mollusc eggs; a few days later this was changed to amphipods 
and mollusc eggs. The greatest variety found at any one time appeared 
in two salmon caught on June 12th, 1913. In these two there were 
cladocera, barnacle larvz, copepods, crustacean sloughs and mollusc eggs 
in abundance, a dipterous insect, a crab larva and a young mussel. 
I know of no reason for their being here in such numbers unless 
there is an especially abundant supply of food for them. This may be 
so, as the waters eddy into the Bay a good deal and many of the smaller
