of Government, turned to anti-malarial work in visiting- 

 malarial tracts and in the breeding and distribution of 

 larvicidal fish. He had experimented at Sunkesula on 

 these larvicides, and had given demonstrations and 

 instructions to local bodies, and had read a practical 

 paper at the Anti-malarial Conference in the previous 

 year ; his success resulted in his deputation to Cuddapah 

 to examine the town and its surroundings and to stock 

 its waters with larvicides. 



This work is likely to prove of immense value in the 

 near future and Mr. Wilson is to be congratulated on 

 his foresight in the experiments made by him in previous 

 years at Sunkesula on the breeding of these larvicides. 



A similar investigation was, by order of Government, 

 carried out by him in company with Major Ross, I. M.S., 

 on the conditions obtaining at Cochin which appeared 

 to favour elephantiasis ; Mr. Wilson submitted a joint 

 report on this matter. 



29. Nilgiri operations. — These under Mr. Wilson, 

 continued to be most successful ; the stock of trout is 

 said to be very great both in the number and size of the 

 fish, and fresh supplies of live fish food had to be intro- 

 duced. 



30. Conservancy operations in the upper waters of 

 the Bhavani and Moyar continued as in previous years. 



31. Pisciciilttu^e — Marine. — Mr. Hornell, f.l.s., as 

 Marine Assistant, writes as follows; — 



Edible oyster-culture. — During the past year the oyster farm at 

 Pulirat became fully stocked with many hundreds of thousands of 

 oysters produced from the abundant spatfall of November 191 2. The 

 growth of these young oysters ha^ been so rapid and satisfactory that 

 it was decided to begin selling operations in January of this year, 

 when the oysters were fifteen months old. The season was therefore 

 opened with these oysters on 23rd January last and between that date 

 and 31st March 1914, 21,450 oysters were sold. The sales of the 

 oysters for the year ending 31st March 1914 amounted to 37,400 and 

 brought in the sum of Rs. 458-12-6. 



Fish farm at Tutlcorin. — In spite of all efforts to expedite delivery 

 the material requisite for the barriers between the lagoon and the sea 

 was not received till January of this year, when it was too late to begin 

 operations as the run of fry necessary for the stocking of the farm 

 was over for the season. All material requisite is now in stock and 

 as soon as the rains come the farm will be stocked and the barriers 

 erected. Meanwhile samples of the fish frequenting the lagoon are 

 obtained at regular intervals whereby much information useful to the 

 future conduct of the farm, is being accumulated.
