putting in hand of the Nallamalai scheme for the growth 

 of larvicides in view to combat local malaria, and other 

 anti-malarial work, and the continuance of trout opera- 

 tions on the Nilgiris. A considerable area was brought 

 under the restrictive operation of section 6 of the 

 Fisheries Act (lY of 1897). Apparently the fishermen 

 have it their own way in the Colair lake and Upputeru 

 rivers for which Mr. Wilson had a promising scheme 

 which, however, is useless if the fishermen cannot be 

 controlled in the matter of stake nets and fixed engines. 

 Mr. Wilson and his staff did a great deal of inspection 

 and work not easily recorded ; among Mr. Wilson's 

 inspections were detailed and lengthy tours in South 

 Kanara and Malabar in view to schemes for stocking 

 and conserving the West Coast rivers ; this is mainly 

 lost labour by reason of his death. He also visited Java 

 and successfully brought back a consignment of gourami 

 which are of Qrreat value. 



The Piscicultural Assistant was busily engaged 

 throughout the year in inspection and supervision, and 

 in making himself acquainted with the work of his 

 branch, the conditions of the country, and the operations 

 in progress ; he was also in charge during Mr. Wilson's 

 absence in Java. 



Sub- Assistant C. G. Chakrapani Ayyangar, b.a., is 

 reported to have done useful work throughout the year 

 both in actual piscicultural operations, in attending the 

 numerous fishery rental auctions, and in supervising 

 ofiice work. The bulk of the report is printed in the 

 Appendix.*

 cal work (Mr. James Hornell, F.L.S.). — f Pearl and 

 chank work was carried on as usual but witli a larger 

 net profit (Rs. 46,400) — entirely from chanks — than has 

 ever yet been attained except when a regular pearl 

 fishery has happened ; nothing was received from pearls 

 during the year, for not a pearl oyster was ever in sight. 

 Mr. Hornell's exertions in chank fishery matters brought 

 about the increased yield from chanks, which, however, 

 would have been far higher had a larger diving force
