the keg. These fish were estimated to be about one-fifth 

 of the school. The keg was then about a foot out of 

 the water, but it still held some water left in as the pond 

 was lowered. On being advised of the discovery the 

 writer went to the pond and the small, compact, grayish 

 school of fry was still in sight. 



Another keg with the lower edge of the opening just 

 about level with the water surface, and located nearer the 

 outlet of the pond, was then examined and it was found to 

 contain a mass of yellowish eggs, approximating a single 

 handful. The eggs formed a very glutinous mass not 

 resting at the lowest point in the keg, but adhering to the 

 lower slightly sloping side near the mouth. A few of the 

 eggs were removed and well-developed and active em- 

 bryos were seen inside the egg cases. An attempt was 

 made by Mr. Southall to photograph the school of fry in 

 the pond, but owing to the roily water and the efforts of 

 the fry to get under masses of algae, the efforts were un- 

 successful. However, pictures were taken of the kegs in 

 situ (Fig. 1) and also of a hole in one of the pond 

 banks (Fig. 2) that appeared to have been made by some 

 of the catfish, perhaps for nesting purposes. As the 

 water in the pond was getting quite warm, the keg with 

 the eggs was removed to the tank house where a picture 

 was taken of them (Fig 3). The eggs were then care- 

 fully tempered from a temperature of 90° F. to 72° F. 

 and placed in a Downing hatching jar at 6:00 P. M. As 

 many of the fry as it was possible to secure were obtained 

 and also placed in the tank house. Later they were placed 

 in a round glass dish and a photograph taken of them 

 (Fig 4). 



Several of the eggs had hatched the following morning ; 

 prematurely no doubt and probably caused by the hand- 

 ling of the preceding day. A large number of the eggs 

 hatched on the 8th. On the morning of the 9th several 

 of the fry were found dead apparently having been 

 smothered under the egg mass. Unlike the fry of the 

 pike perch, or buffalo fish, they do not rise after hatch- 

 ing, but keep close to the bottom and as there was no
