On the Introduction of Trout and Tench into India.

[Bead April 6, 1876.] 



DuEiKG the last few years three attempts have been made to in- 

 troduce European fish into the rivers and tanks on the Neilgherry 

 Hills in the Presidency of Madras, It may now be assumed that 

 at any rate the Trout {Sahno levenensis) and the Tench (Tincc vul- 

 garis) have bred there, and may prove an eventual success. 



The first trial was made by Mr. Thomas, of the Madras Civil 

 Service, who took out a few hundred trout-ova in the ' Eipon ' in 

 1863. Erom various causes they died prior to reaching India. 



In 1866 I made the second attempt. The eggs were obtained 

 for me by Mr. Erank Buckland, and were in an excellent state 

 when packed. This process was performed by myself, as I had 

 previously been instructed by Mr. Toul ; and six small boxes of 

 ova were placed, Eebruary 2nd, in the ice-room of the P. & O. 

 steamer ' Mongolia ' at Southampton. On March 12th, they were 

 landed at Madras. On the 14th they reached the Government 

 G-ardens at Ootacamund, where the Superintendent, Mr. M'lvor, 

 had prepared a very suitable house for their reception. Through 

 it flowed a stream of clear water. Things went on pretty well for
