Although statistics for the first and second expeditions are given above, 
no attempt at comparison should be made. The ’’Dorothy’s” catch during the 
first expedition was confined largely to Canoe 3a v: the catches of the ves- 
eels of the second expedition extend from Cape Spencer to .Ugnshik in Bristol 
Ba v . During the first expedition an attempt was made to thoroun Iv fish only 
the places crabs were located in significant quantities. So far in the 
second expedition, on the other hand, an attempt has been made to cover as 
much territory as possible in order to determine the extent of the distri- 
but ion of the Alaska crab population. Consequently, the vessels have been 
leaving large bodies of crabs as soon as some idea of the productivity of a 
Particular area has been obtained

is means, of course, that the catch 
par boat is much less than would have been expected if the vessels had con- 
tinued to work on the bodies of crabs located. It would appear , however, 
that the consistency with which catches have been made under rapidly moving 
exploratory procedure, indicates a considerable population of crabs available 
to support an industry, much valuable information is being obtained on the 
biology and habits of king crabs since the biologists have been able to make 
extensive observations on spawning habits , the moulting procedure, nd the 
movement of populations, as related to spawning end moulting . The fishing 
observers are also obtaining much instructive data as to the relative .merits 
of different -goes of gear under varying conditions and of the selectivity 
as influenced by the changing physical conditions of the crabs
