[7] PROPAGATION OF THE SCHOODIC SALMON, 639 
the fish were turned out and where he afterwards saw traces of their 
having scratched about. He thinks they do not linger on arocky shore, 
but do ona sandy shore. I think that on a shore of proper grade, say 
fine gravel (or coarse sand, like Mayberry Cove), the fish might find bot- 
tom on which they might be satisfied to finish their digging for the sea- 
son, instead of returning to the stream. The men got back this trip a 
little after 11 o’clock. 
November 18.—This morning quite a number of fish in the outer 
pound, and among them undoubtedly some of those that were carried up 
late last night. We know them by their abraded noses, which a great 
many of the males had. 
November 19.—Sent up four boat loads of fish to-day. 
November 20.—Sent up four boat loads of fish to-day. 
November 22.—Windy and cold. The ice has prevented our doing 
anything at boating fish since 20th. Have not given up hopes of being 
able to dosomething more in that direction, but don’t expect to get any 
more good fish. Have therefore lifted the nets around the first and 
second pounds, and let all the fish hereafter coming in escape. 
November 23.—Lake closed last night for half a mile up. 
November 24.—This morning I heard the ice cracking and snapping 
about 4 a. m.,and after. This did not attract my attention at first, but 
when it did I merely supposed that the saw-mill had been started at an 
early hour, and had, as usual, drawn down the water near our house. But 
between five and six o’¢lock it occurred to me to go down to the stream 
and look. I found the water very low, and could hear no sound of 
rushing water from the dam. Iran up to the dam and found that all 
the gates (seven, and all open) were clogged up with anchor ice so that 
no water could be perceived running through. Weimmediately turned 
to with shovel and pick and soon had the water running again. This 
was Similar to the jam of two years ago. I thought then that the ice all 
formed above and merely came down with the wind, but I amsure that 
inthis instance the ice must have formed in the gates or close above 
them, for there was a sheet of ice across above at the old coffer-dam and 
nearly all the way as far as we could see. Apparently the water did 
not cease to runin our hatching troughs, and no harm was done. 
November 25.—Lake frozen almost as far as we can see. All the fish 
on hand (say 500) let loose. Nets all submerged (except the cross-net, 
to prevent fish running down to the dam and the canal net). They 
were so frozen to stakes and encumbered with ice that I could not hang 
them on stakes as I had intended, so sunk them and kept them down 
with the chains and stones to thaw out. 
November 26.—1 find at old hatching house 20.33 gallons of water per 
minute. Of this the north aqueduct furnishes 4.28 gallons; west aque- 
duct, 6.00 gallons; old spring, 10.05 gallons. Temperature of water in 
the hatching troughs 41°. Tested the Widdifield thermometer in use 
there, and found the mercury to sink 4 degree below the mark at freez-
