has been described in some detail in an inspection note 

 printed in G.O. No. 782, Revenue, dated 15th March 

 19 1 3, which led to a demand from the Government of 

 India for copies of the farm plan. 



Minor operations consisted in the stocking and 

 conserving of several large tanks, while conservancy 

 operations proper were also conducted as usual in the 

 upper Vv^aters of the Bhavani, Moyar, and Cauvery. The 

 hilsa-hatching operations on the Coleroon were a failure 

 in 19 1 2, owing to the difficulty in obtaining ripe females. 

 Mr. Wilson observes that this difficulty occasionally 

 happens in America with shad, and technical papers 

 lately received from the United States of America show 

 that this has just occurred there on a large scale. 



Mr. Wilson's more difficult work lay in working out 

 certain important projects, viz., that at Allur in Nellore, 

 to take the place of the Kanigiri project to which the 

 Public Works Department refused assent for technical 

 reasons relating to the Kanigiri reservoir, and a new 

 one at the Colair lake in which floating hatchery is to 

 provide swarms of hilsa fry which should not only greatly 

 increase the yields of hilsa in the Godavari and Kistna 

 rivers, but furnish stock for transport to the west coast 

 rivers ; in addition to the hilsa hatchery a large murrel 

 farm will be located in a position whence the fish can be 

 transported in quantities by rail to various markets. 

 Both these projects are still in the stage of investigation. 

 Mr. Wilson is also engaged on a scheme for acclimatising 

 tench from the Nilgiris for use in our waters on the 

 plains. 



Incidentally in boring for fresh-water at Nellore it 

 v/as discovered that semi-artesian water was available, 

 the water rising in a 70-ibot bore to within 3 feet of the 

 surface after the tools had passed through a thick bed of 

 clay ; this fact may be of use agriculturally. 



The Nilgiri trout prospered during the year and 

 Mr. Wilson reports that Rs. 1,495 were obtained 

 from licenses. Poaching by men and otters unfortunately 

 developed, and the supplies of fish food proved insuffici* 

 ent for the large head of rapidly grov/ing fish, some 

 weighing 6 lb. and over, so that Mr. Wilson has had to 

 introduce shrimps and other live food from lower waters. 



A most useful investigation was made at Sunkesula 

 in the growth and observation of various classes of fish
