302 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
lances, and other implements that have been used for the capture 
and handling of whales by the fishermen of this country. Brief descrip- 
tions of these are given on pages 334-337. 
In addition to illustrating the work of the Commission by means of 
drawings, paintings, and photographs, arrangements were made with 
the American Mutoscope and Biograph Company, of New York, to 
utilize the mutoscopes. A very interesting exhibit was furnished, the 
phases of the fisheries shown being as follows: 
Catching cod. Kittery Point, Me. 
Taking and fertilizing the eggs of the cod. Kittery Point, Me. 
Lifting a lobster pot. Kittery Point, Me. 
Landing a haul of shad. Avoca, N. C. 
30ating a shad seine. Avoca, N. C. 
Angling for large-mouth black bass. Occoquan, Va. 
Capt. Paul Boynton feeding sea lions. Coney Island. 
View of Fulton Market, New York, ona busy day. 
Angling for large-mouth black bass. Muskoka lakes, Ontario, on line of Grand 
Trunk Railroad. 
Unloading a halibut vessel. Gloucester, Mass. 
Unloading a cod vessel. Tee Wharf, Boston. 
The scenes shown in the mutoscope are obtained by making a series 
of photographs of the moving objects on a long band of celluloid film 
at the rate of 1,800 pictures per minute. The time interval between 
the successive pictures is thus only the thirteenth part of a second. 
Photographic prints are then made froma strip of negative pictures, 
and these prints are arranged in regular order around a cylinder. 
When the cylinder is revolved the cards are allowed to snap forward 
one after another, thus presenting the photographs to the eye in the 
order and at the same rate of speed at which they were originally 
taken. The velocity is so great that the eye does not appreciate the 
change from one picture to another, and the observer seems to be 
looking at one picture, in which the objects move as did the original. 
By this process any moving scene may be faithfully reproduced. The 
rapid flight of an express train, the movements of a watch, the maneu- 
vers of a war vessel, and the movements of an insect are scenes which 
may be reproduced and which illustrate the possibilities of the art. 
COURTESIES RENDERED TO THE COMMISSION. 
From the U. 8. National Museum were obtained numerous speci- 
mens of crustacea and economic mollusks, besides models of vessels, 
and the historical collection of swivel guns, rockets, lances, etc., used 
in the whale fishery. The officials of the Museum cooperated most 
heartily with the Commission in all matters. 
The Commission is under obligations to Mr. Howard Page, 26 Broad- 
way, New York, for the loan of three tank cars belonging to the Union 
Tank Line Company, used in transporting salt water from Woods 
Hole, Mass., to Buffalo. 
The superintendent of the New York Central Railroad, Mr. J. P. 
Bradfield, rendered material assistance in transferring, free of charge,
