18 REPORT OF THE COMMISSIONER OF FISHERIES. 
The steamer “ish Hawk continued the experimental shad work on 
the Kennebec River until the end of the season, then during the 
remainder of the summer of 1906 was utilized in biological sur- 
vey of Buzzards Bay. In the fall she was sent to Florida waters to 
assist the efforts toward the propagation of mullet and later of shad 
in the St. Johns River. At the close of the year she was in Hampton 
Roads in connection with the exhibit of the Bureau at the Jamestown 
Exposition. 
The schooner Grampus was engaged in the collection of egg-bear- 
ing lobsters for the Maine hatchery and the planting of young lob- 
sters along the Maine coast till the latter part of September. She 
was then dismantled at Gloucester, Mass., in anticipation of the 
extensive repairs provided for by act of Congress, and her crew was 
detailed to assist in the work of the Gloucester station. A bid for 
the repairs having been accepted from a firm in Boothbay Harbor, 
Me., the vessel was dispatched to that point in June, 1907. 
JAMESTOWN EXPOSITION. 
Tn the act of Congress directing the participation of certain Gov- 
ernment departments and bureaus in the Jamestown Ter-Centennial 
Exposition near Norfolk, Va., the Bureau of Fisheries was specific- 
ally mentioned and provision was made for a fisheries building, in- 
cluding an aquarium. Preparations were begun in September under 
the direction of the representative on the Government board for the 
Department of Commerce and Labor, and the first shipment of ma- 
terial was made the latter part of January. The exhibit was in place 
and ready on the opening day, April 26, but owing to lack of electrical 
power and an adequate supply of fresh water, both of which impor- 
tant factors were to have been furnished from outside sources, it was 
necessary to postpone opening the aquarium for one week. 
The building provided is connected with Government building “A” 
by a colonnade and contains 6,200 square feet of space, of which 2,650 
square feet are occupied by the aquaria and entrances. The aqua- 
rium consists of 19 tanks arranged about the sides of the building and 
a central pool for seals, turtles, and other large animals. Owing to 
the desirability of giving particular attention to an exhibit of marine 
life, but small space was left available for illustration of the func- 
tions of the Bureau by a fixed exhibit, and only a select number of 
models, apparatus, etc., pertaining to the more salient or interesting 
phases of the work, could be displayed. 
PUBLICATIONS AND LIBRARY. 
The Bureau’s publications in 1907 amounted to 1,077 pages and in- 
cluded 15 pamphlet: articles. The Bulletin was carried into its 
twenty-sixth volume. The number of pamphlets supplied to ad-
