ber and November in connection with the residue of bass 

 collected when the ponds are drawn for cleaning. There is, 

 apparently, no cannibalism among these species. 



After the young fish are taken from the pond with the 

 seine the tub in which they are carried is placed under 

 a half inch bibcock to equalize the temperature after 

 which they are transferred to a trough. From there they 

 are counted and placed in the transportation cans. If the 

 shipment is intended for an early morning train the cans, 

 covered with a bobinet screen are set under a 2 inch pipe 

 which supplies water to the cans through half inch bibcocks 

 and they are held thus till time to load them for shipment 

 next morning. 



All bass shipped to one applicant for planting in the same 

 pond should be the same size. When fry and fingerlings 

 are planted together the chances are ten to one the fry will 

 become food for the fingerlings. Plants should be made in 

 shallow water containing suitable pond vegetation in which 

 they may find an avenue of escape from enemies and where 

 the food supply is more plentiful. When young fish are plant- 

 ed in a new pond containing no vegetation they should be 

 fed on finely chopped beef heart two or three times each 

 week. Suitable pond mosses should be set in a new pond 

 as the water in turned in for the first time. 



The number of fish shipped in a transportation can de- 

 pends on the size of the fish. 1,000 advance fry, 600 No.l 

 fingerlings, or 200 No. 2 fingerlings per can have given the 

 best results in shipments from this station. If the cans are 

 overloaded there is considerable loss of fish and those sur- 

 viving the trip are in a weakened condition. Having lost 

 the disposition to search for food they consequently die of 

 starvation. Every possible efl'ort should be put forth to 

 deliver the fish to the applicant in first-class condition, as 

 this is the chief end and aim of propagation. 



A change of method in some features of the distribu- 

 tion inaugurated during the early part of the fiscal year 1922 

 has resulted in a reduction of the cost of more than 50 per 

 cent during the last two years, as compared with former 

 years. During the fiscal year 1921, under the old method, 

 the average cost per thousand for distributing the fish from 

 the Orangeburg station was $5.60. Under the new method 

 the cost was $1.93 per thousand in 1922, and $1.99 in 1923. 

 The method consists in sending a messenger with fish to a 

 central railroad point with instructions to ship from various 

 points enroute to applicant living on connecting lines, in care 

 of the train baggageman, or by express. On arrival at his
