onh' the tails are used. This flesh is then placed on a chopping 

 Ijoard and choiJiJcd very fine. Then it is nni through a plate 

 having- perforations of 1-33 of an inch. This screening is then 

 mixed with water to the consistency of cream and fed to the 

 small fish. As they increase in size minnows, young carp, and 

 mud shad (Dorosoma cepedianum). The fry of this latter fish 

 is the finest food for young Ijass I know of and all pond cultural 

 stations should have a pond provided to rear this class of young 

 fish. 



I give experiments made with young bass several years ago 

 to determine the most suitable sizes to transfer from brood to 

 nursery ponds and since then no fish have been transferred under 

 one and one-fourth inches in length, they are then fish and can 

 be held with some certainty of getting a fair per cent distributed. 



First Experiment. — ^1,000 young bass one and one-half inches 

 long were placed in a pool six by sixteen feet and one and one- 

 half feet deep. At the end of one month the loss by death was 

 126, and by cannibalism 139, the greatest loss from death was 

 during the first two weeks. The largest number that died any 

 one day was twelve. These fish were fed on the flesh of perch 

 prepared as above described. 



Second Experiment. — 1,000 fry Just after food sack was ab- 

 sorbed were placed in a pool six by sixteen feet and one and one- 

 half feet deep, supplied with small insects gathered in moss from 

 river, and many water fleas (Daphnia). After the third day 

 they commenced to die, the greatest loss was seventy-one in one 

 da}^, and at the end of the month there remained, in round num- 

 bers, 200, and these were not in good condition. 



Tliird Experiment. — 1,500 young bass from two to two and 

 one-half inches in length were placed in a section of pond six- 

 teen hy fifty feet. This pond had a fine gi'owth of water plants 

 (Myriophyllum) and in it were great quantities of insect life. 

 These fish at the end of the month were in fine condition; 1,240 

 were shipped out and distributed. The result showed a loss of 

 260, and ten of these died from effects of handling during trans- 

 ferring. The 250 lost I attributed to cannibalism. 



Fourth Experiment. — 5,000 fry (number estimated) were 

 placed in section of pond sixteen by sixty feet. At the end of 

 one month 750 were found. This pond was well supplied with
