brought down the inlet of the hatching boxes and will hasten growth, for 

 fish will never grow unless they have " range." In a box most of the food 

 is taken by the stronger fish, unless they are fed with greater care than the 

 average Indian keeper is capable of and the strong fish very soon take to 

 feeding on their weaker brethren. 



Planting fry. — By May and June it should be possible to have all the fry 

 out in Nursery streams. They should be collected from the Rearing Pond 

 in the evening after six hours at least of starvation, and placed in 4-gallon 

 tin carriers (Fig. iv) : each carrier will for an ordinary journey up to 16 hours 

 carry 500 fry. The top should consist of a perforated tray exactly like the 

 tray of an ordinary "live bait can." The tin should fit into a wooden 

 frame on rockers* : and this should be covered with cloth to be kept wet so 

 as to reduce temperature by evaporation in sunshine. The first part of the 

 march should always be done at night. With each carrier should go a live 

 car {vide Fig. v) the upper part of perforated zinc, the lower of tin : at the

bottom is a hole with a cork in it. Whenever it is necessary to rest fry the 

 live car can be placed in cold running water : the fry are poured into it, 

 and allowed to swim about in the "car." When the car is lifted up all the 

 fry will be in the tin at the bottom : the car is held over the carrier, the 

 cork drawn, and the fry fall back into the carrier. It is absolutely essential 

 in India never to " handle '' fry if it can be avoided ; and with this apparatus 

 specially devised in Kulu, we have moved trout fry as well as coarse fish 

 for journeys of three or four days at midsummer with trifling loss. That is 

 the whole process of stocking : "eyeing " ova: and planting out either eyed 

 ova or three months old fry as circumstances require. It has not been evolved 

 without mistakes and disappointments. It would never have worked at all 

 but for Mr. Mitchell's help and advice.

Photographs give a fair idea of the Rearing Ponds and the Stock Pond. 

 The latter is unfortunately some 2 miles from the former owing to my 



* The rockers are to enable a hill coolie to rock the carrier with his toe when 

 he is resting or smoking. Such rocking keeps the water aerated-
