at the expense of the United States Fish Commission for the benefit 
of American oyster growers, but European and especially English 
people interested in the oyster industry are likely to obtain still more 
advantage and benefit from his careful work than Mr. Dean’s own 
countrymen, and we owe a debt of gratitude to the Commission for 
thus providing us with reliable and important information without 
any cost or trouble to ourselves. 
In reference to the Wood’s Holl station the Commissioner reports 
that Dr. H. V. Wilson was appointed resident naturalist on behalf 
of the Commission in 1889, and served in that capacity in the two 
following years. His researches related chiefly to the development 
of the sea-bass, cod, and Atlantic salmon. An elaborate paper on the 
Embryology of the Sea-bass by Dr. Wilson is contained in the Bulletin, 
vol. ix, 1891. The study of the lobster was taken up at Wood’s 
Holl by Prof. F. H. Herrick, and experiments in artificial propaga- 
tion were conducted by Mr. V. N. Edwards. We are told that the 
investigations of the latter have furnished conclusive proof that the 
hatching work of the Fish Commission has been exceptionally suc- 
cessful in increasing the supply of cod on the southern New England 
coast, and shows that the larger fish resulting from these plantings 
will to some extent enter more shallow waters than are generally 
frequented by the cod, shoals of this species now often making their 
appearance in places where they were never seen before. ‘The evi- 
dence for this would be interesting, and we shall see whether it is 
forthcoming among the documents published by the Commission, 
The Report next mentions the investigations of the interior waters 
of several of the States, which were extensively and systematically 
carried out, and reports on which have appeared. A brief notice is 
then given of the inquiry into the methods and statistics of the 
fisheries, on which a special report is included in the volume. The 
rest of the Commissioner’s Report is on the Department of Fish 
Culture which is under the chief’s immediate direction. Twenty-two 
stations were in operation in 1890 and 1891. Sea fish were only 
manipulated at two stations, namely, Gloucester, Mass., and Wood’s 
Holl, Mass., but in addition a few eggs of Spanish mackerel were 
hatched on the “ Fishhawk” in 1891. The eges of the cod were 
hatched in the largest numbers, namely, in round numbers 19 millions 
at Gloucester, 386 millions at Wood’s Holl in 1891; at the same 
station in that year were hatched 38 million flat-fish fry and 3 
million lobsters. The shad was still the fish most extensively 
treated in the operations of the Commission, nearly 70 million fry 
having been furnished for distribution in 1891. Altogether the 
number of different kinds of fish artificially propagated was thirty- 
eight, of which ten were marine, the rest fresh-water or anadromous,
