hatch normally. Eggs were stripped from the others and placed in 
McDonald hatching jars for incubation. On June 30, there had been 
hatched 3,899,000 lobster fry, of which 1,045,000 were placed in the 
rearing station, the remainder being liberated. 
On September 21, 1938, the Woods Hole (Mass.) station was struck 
by a hurricane and tidal wave which destroyed windows, lattice work, 
slate shingles on the roofs, docks, sea wall, salt-water suction pipe 
line, and other property. The wooden portion of the east dock and 
sea wall was razed. Considerable time and funds will be required to 
rehabilitate this unit. The new suction line has been installed and 
other necessary repairs were made in order that the station could carry 
on its flounder work. Approximately 633,987,000 flounder eggs were 
‘collected and 568,530,000 fry were hatched and distributed. Ap- 
proximately 50 percent of these fry were liberated in the coastal waters 
of Massachusetts—the remainder being planted along the coasts of 
New Jersey and Rhode Island, and in Long Island Sound and Narra- 
gansett Bay. Through the cooperation of the local commercial 
fishermen, there were collected 13,484,000 mackerel eggs from which 
11,060,000 fry were hatched and liberated in Vineyard Sound and 
Buzzards Bay. 
The fish-cultural activities at the Gloucester (Mass.) station con- 
sisted of the propagation of pollock, flounder, haddock, cod, and lob- 
ster. There was a noticeable decrease in the production of the three 
former species, whereas there was a slight increase in the number of 
cod handled. Several spawn-takers were assigned to commercial 
fishing vessels for the purpose of collecting pollock, haddock, and cod 
eggs, a large percentage of which, after fertilization, were planted 
on the spawning grounds. The hatchery was also operated to capac- 
ity when eggs were obtainable. The total number of eggs collected 
was slightly in excess of 344 billion. The lobster-cultural work was 
carried on in cooperation with the Massachusetts Department of Con- 
servation, the same as last year. Four hundred and ten seed lobsters 
produced 3,221,600 eggs which were incubated in McDonald hatching 
jars. Due to insufficient feeding equipment, it was necessary to 
liberate the greater percentage of the young lobsters in the third 
larval stage. Under the auspices of the P. W. A. and W. P. A., the 
buildings and equipment at this point were reconditioned and over- 
hauled. Major changes consisted of the following: 15,000-gallon 
storage tank constructed, main hatchery building, storehouse and. 
workshops reroofed, extension constructed on southwest side of 
boiler room to provide additional space for new boiler, new boiler 
installed as a replacement for the obsolete boiler, wharf repaired, new 
concrete floor poured in hatchery building, and all buildings given 
one coat of paint. 
GREAT LAKES SPECIES 
As Michigan maintains a closed season during the height of the 
spawning period for whitefish and lake trout, the collection of eggs of 
these species by the Duluth (Minn.) station was restricted to collect- 
ing fields in that section of Lake Superior not controlled by the State 
of Michigan. Al lake trout and whitefish eggs obtained in Michigan 
waters were taken either before or after the closed season, and were 
of an inferior quality, with a resultant poor hatch. About 5,325,000 
lake herring eggs were obtained from commercial fishermen from which
