APPARATUS FOR TRANSPORTING EGas. 
Clark white-fish-egg box: 
Wooden case, with hinged door, con.aining twenty trays. This case is used 
chiefly for the transportation of the eggs of the white-fish and lake trout from field 
stations on the Great Lakes, and was designed by Mr. Frank N. Clark, of Northville, 
Mich. Eggs have frequently been held on these cases from fifteen to thirty days 
before they reached the hatchery, without suffering material loss. 
Annin’s egg-transportation box: 
This apparatus consists of an outer case which contains a smaller one, surrounded 
by sawdust to prevent loss of eggs from sudden change of temperature. The inner 
case is provided with trays, with canton-flannel bottoms, for holding the eggs. 
There is a small ice chamber between the outer and inner boxes, and the bottom of 
the outer box is provided with wooden strips to prevent its coming in contact with 
the surface on which it rests, which would prevent drainage. 
Devised by James Annin, jr., Caledonia, N. Y. Boxes of this patent have been 
used for sending eggs of trout to Europe. 
Atkins’ s transportation box: 
A wooden box containing three smaller boxes, in each of which 15,000 salmon 
eggs are placed upon layers of muslin. The space between the larger and smaller 
boxes is filled with moss to prevent an unhealthy change of temperature, and the 
layers of eggs are separated from each other by wet moss. Eggs packed in this way 
can be sent several thousand miles with very satisfactory results. 
Devised by Charles G. Atkins, Bucksport, Me. 
Seagle’s egg-transportation box: 
This apparatus consists of a wooden box, with hinged cover, 21 inches long, 19 
inches wide, and 183 inches high, containing 6 canton-flannel trays, 114 inches by 93 
inches, on which the eggs are placed, packed in moss. A wooden hopper above the 
trays holds crushed ice, and the space around the trays is tightly packed with sphag- 
num moss. Eggs of the Salmonidee are successfully transported long distances by 
means of this apparatus. 
Devised by George A. Seagle, Wytheville, Va. 
McDonald’ s egg-transportation crate: 
A crate containing eighteen shallow trays or wooden frames, with wire-cloth bot- 
toms, incased in canvas and secured by frames connected by leather straps. Length, 
16 inches; height, 15 inches; width, 14 inches. This crate is used for transporting the 
eggs of the shad for a distance of 50 to 100 miles. The bottoms of the trays are coy- 
ered with wet cloths, upon which the eggs are spread. Each tray holds from 10,000 
to 15,000 shad eggs. When filled they are incased in the cloth cover, securely 
strapped together, and shipped by boat or rail to the hatchery. This apparatus 
marks the beginning of the dry transportation of shad eggs, and has been success- 
fully used in the work of the U. S. Fish Commission since invented. 
Invented by Marshall McDonald, 1881. 
APPARATUS FOR TRANSPORTING FRy. 
Model of U.S. Fish Commission car No. 3 (scale of 1 inch to the foot): 
This car was built in Wilmington, Del., by the Harlan & Hollingsworth Com- 
pany in the month of November, 1897. Total length of frame, 60 feet; width of 
frame, 9 feet 6 inches; total length of car from ends of platforms, 67 feet 10: inches; 
height of car from top of rail to top of roof, 13 feet 10 inches. The frame of the car 
has a special bracing in order to allow the two large doors in the center of the car to 
extend from floor to roof. The trucks for the car were made by the Pullman Com- 
pany, each of them having six 33-inch Allen paper wheels. The interior finish of the 
car is of light-color ash. In one end of the car is an office, and next to it an ice 
box—capacity of about 13 tons—and a water tank holding about 500 gallons. In the 
center of the car are two compartments for carrying its load. The fish are carried in 
cans and square tanks, according to the size of the fish. The size of these compart- 
ments is 30 feet long, 3 feet wide, and 25 inches deep. A hatching apparatus of a 
capacity of 45 McDonald jars is also used on this car, and is placed on the top of the 
two compartments for carrying fish after moving the lids. The jars are placed in 
lead-lined boxes, which areof the same size as the lids and about 6 inches high. The 
supply of water is taken from the pressure tank. It flows from the lead-lined boxes
