[11] PROPAGATION OF THE SCHOODIC SALMON. 643 
packing-box, making about 15,000 eggs in all, in the same style as 
usual for shipment, and let them stand in the back part of the room. I 
suppose there the temperature stood at about 34° or 35°, and that they 
were as wet as those sent away. This a.m. we opened them and found 
that they have kept well, except that about 10 per cent. of them have 
shrunk some and are indented on the side; a few were burst. Not 
likely to send these away again without some picking. We took out. 
what shrunken ones we could see after turning them out into pans of 
water. Those taken out, numbering about 1,000, we place upon a tray 
to keep and hatch. After several hours in the water they seem to have 
about all swollen out to original size. During the first hour in water 
but few of them swelled out completely. These weak shells have a 
greater transparency than the others. Ihave not yet perceived any- 
thing inferior in the appearance of the embryo. So far as I have ex- 
amined, they appear of good size, good color, and with strong veins. 
After the plump eggs (from which the shrunken ones had been taken 
out) had been in water a few hours they were packed up again and 
went to McDonald, whose package was made up from lots of 8 and 9. 
I do not think this shrinking is due to the water being exhausted by 
an overstock of eggs. Were this so, the eggs at the upper ends of the 
the troughs would be good and those at the lower ends bad. However, 
to test this, I have packed up two small trays from lot 9, of which 5,000 
same from the lower stack, in trough 8, and the other 5,000 from upper 
stack, in trough 9. These are appropriately marked and stand in the 
back part of the hatching-house. 
I also overhauled three boxes put up to test modes of packing against 
cold. They were packed Saturday afternoon and left in the hatching- 
house till near 10 p. m., when I put them outdoors on the tops of some 
old hatching troughs arranged right side up, so that the air had access 
to them on all sides except merely the edges of the sides of the trough. 
These were packed as if containing eggs for shipment. Inside were 
trays full of wet moss, and around them 3 inches of dry protecting ma- 
terial, one of dry sawdust, one of dry leaves, and one of dry moss. The 
first (with sawdust) was a good deal frozen—I think an average of 
three-eighths of an inch from all sides into the inside moss. In the 
other two the frost had penetrated, as near as I could judge, an average 
of not over three-sixteenths of an inch from all sides—in some places a 
good deal less, of course—this average including the edges and corners, 
where the frost had penetrated much deeper. I cannot say surely that 
there is any difference between the dry moss and leaves. If eggs had 
been in these boxes they would not have frozen, but part of those in 
the sawdust would. 
These boxes were put outdoors Saturday at 10 p. m., temperature 
then being +14°. Next morning temperature was +11°. As soon as 
the sun was high enough the boxes were put under a shed, in the shade, 
but were brought out again after sundown, temperature +119; at 7
