H.— FISHCULTURAL AND TRANSPORTING APPARATUS. 



29. COLLINS' EGG-PAN (sec fig. 5). 



This pan was devised by the writer for collecting fish-eggs at sea. 

 It was found in practice that the ordinary tin pan commonly used for 

 collecting fish-eggs on shore was unfit for 

 collecting eggs when it had to be used on 

 board of boats and vessels in a sea-way, 

 where there was much motion, and also had 

 to be passed from boats to vessels, or vice 

 versa. 



The pan is oblong in form, with a tumble- 

 in top, provided with an iron bail and tin 

 cover, the latter preventing the loss of eggs 

 from slopping out and the former facilitat- 

 ing the handling of the apparatus in the boat. The pan is 18£ inches 

 long, 10^ inches wide, aud 8J inches high exclusive of the cover. It is 

 made of tin and covered with asphaltum inside to prevent corrosion 

 from contact with the sea-water.

30. MCDONALD'S HATCHING BUCKET. 

 (Plates xvn and xviii.) 



This device was invented by Gol. Marshall McDonald, U. S. Com- 

 missioner of Fish and Fisheries, for the purpose of keeping alive, de- 

 veloping, and hatching (if necessary) such floating eggs of pelagic 

 fishes as might be taken on board the Grampus in the towing nets. 



The device consists of an ordinary iron-bound pine bucket, provided 

 with an iron bail and fitted inside with two perforated wooden dia- 

 phragms : one of these is placed near the top of the pail and the other 

 about 1J inches from the bottom, each resting on a wooden flange 

 screwed to the inside of the bucket. There are nine holes in each dia- 

 phragm, one of them being in the center and the others arranged in a 

 circle around it. These holes are large enough to receive glass tubes 2 

 inches in diameter and 7 inches long, these being the same as those
