[13] PROPAGATION OF WHITEFISH AT NORTHVILLE, MICH. 565 
Diary in connection with the preceding table. 
October 25.—Weirs examined fish at Snide’s pounds. Ripe males 
numerous, but no ripe females. 
October 26.—Fish handled as before. No appreciable difference to be 
seen. 
October 27.—Examined about 1,000 whitefish, lifted from seven pounds. 
Milters plenty, and large females softening. 
October 28.—Pounds not lifted; high winds. 
October 29.— Abundance of ripe males, but no ripe spawners. 
October 30.—Females getting quite soft. 
October 31.—Six ripe females found. About two males caught to one 
female, and nearly half of them ripe. Eggs placed in floating boxes. 
November 1.—High westerly winds, in consequence of which only two 
of Mr. Snide’s pounds lifted. Eggs obtained were placed in floating 
boxes. 
November 2.—Very pleasant day. About one in fifteen of the females 
ripe. Eggs deposited in floating boxes. 
November 3.—Warm and pleasant. Three pounds visited in forenoon 
by Weirs, and four in afternoon by Weirs and Bower, the latter of 
whom arrived from Northville at 12 m. The best day of the season for 
operations, as lake was very calm. Eggs secured in good shape and 
well milted. Those taken in the forenoon were placed with those pre- 
viously deposited in the two floating boxes on hand. Eggs obtained in 
the afternoon excecding the numbers on hand, it was feared that injury 
might result from having them too deep in the floating boxes; accord- 
ingly two more boxes were hastily improvised, the eggs, however, being 
allowed to stand in the pails six hours, with changes of water every 
forty minutes, becoming almost perfectly hardened before being trans- 
ferred thereto. But when all were taken up for shipment, no noticeable 
difference was apparent between these and the others that had been 
deposited in the boxes immediately on arrival of the pound boat at the 
dock, and while the eggs were yet quite soft. 
November 4.—Egegs obtained to-day were retained in pails six hours— 
water changed ten times—and then spread in double layers on the flan- 
nel trays for shipment. A narrow margin of flannel was left unspread, 
so that eggs did not come in contact with the tray frames, and the trays 
were thoroughly sprinkled or immersed before receiving the eggs—pre- 
cautions that were observed with all subsequent shipments from this 
point. 
November 5.—Eges taken to-day, after standing seven hours, with 
hourly changes of water, were, together with those in the floating boxes, 
transferred to the carrying cases, the next day being regular boat day 
for Detroit. Eggs were dipped from the floating boxes with a small tin 
strainer into a pail partially filled with water, then transferred in like 
manner to the trays, being held in the strainer until pretty well drained,
