164 Thirty-fourth Annual Meeting. 
ent season, 1905, is 192,000; the entire total for all previous 
years is 103,796. The largest number reported from any other 
station is 3,750, reared by an apparatus of the same principle at 
Wood’s Holl in 1902. 
In ascertaining the number of lobsters reared to this stage 
the methods of estimating are not trusted, but the lobsters are 
counted one by one as they are dipped out of the water with a 
tea strainer fastened to the end of a stick. 
It is obvious, of course, that the output of “lobsterlings” 
might depend upon the number of newly hatched fry available 
and on the extent of the apparatus. ‘Taking these things into 
consideration the comparison is still more favorable to our sta- 
tion, for in most, if not all, other stations the supply of fry 
has been greater and the per cent of lobsters hving through 
the three moults smaller. 
The exact proportions of newly hatched young reared to 
the fourth stage can be ascertained accurately only by counting 
the number at the beginning and at the end of the experiment. 
The time required for counting is so considerable that only 
in few cases were the fry counted at the beginning of the ex- 
periments. 
On June 7 and 8, 1905, 20,000 in the first stage were count- 
ed and placed in one bag. The “fours” began to appear in 
ten days and all that lived reached this stage before the end of 
the twelfth day. 9,635 lobsters in the fourth stage were counted 
from this twelfth bag; a yield of 48.1 per cent. 
On June 28 and 29, 20,000 young fry, of the first stage, 
were counted into one bag. From this lot 8,178 in the fourth 
stage were counted; a yield of 40.8 per cent. 
These two experiments illustrate very well the general 
results of the season’s work, as there was no extraordinary care 
given them nor were they conducted under especially favorable 
conditions. 
The proportionate yield is large as compared with that 
of other stations. The largest of these reported heretofore is 
6.6 per cent.; Appelof, of Norway, and 21 per cent. at Wood’s 
Holl, where the Wickford apparatus was used. The 6.6 per cent 
was obtained as an experiment beginning with 1,500 fry in the
