STEWPONDS. 
5. In compliance with the Resolution No. 3, 
passed on the iSlh November, 1898, most of the 
young fry were turned into Stewponds, of which 
three new ones, A, B and C, were constructed at 
the hatclieries, two on the Horton Plains, two on 
Calsay, Nanuoya, one at St. Leonards, Udapus- 
sellawa, and one at High Forest, Maturata. The 
upper pond ou the grounds ot the Queen's Cottage 
was also utilised for the pur))ose. 
At the Hatcheries, 4,230 Brown trout try were 
placed in four stewponds, and 324 Rainbow Trout 
fry in two stewponds. These stewponds were 
emptied on the 1st, 2nd and 4th October, immedi- 
ately after the close season had commenced, with 
the following results. The number of Brown 
Trout fry was 796, the greatest length being 7 
inche.s. and the average was 4 inches, their age 
being then 7^ months. The number of Rainbow 
fry was 170, and the average length was 4J inches 
their age being then 6 months. The whole seemed 
healthy, and in fair condition, the Rainbow fry 
especially being very game, thriving excellently 
on their diet of fresh water shrimps : there was, 
however, a great diversity in the growth of the 
consignment, a number having hardly grown at all. 
At the time when the Brown trout fry were tur- 
ned oat into the stewponds, the daily mortality 
was serious ;and ic is probable that they were not, 
as a whole, in healthy state. Whenever any 
fry show signs of weakness they are attacked and 
eaten by the healthier fry, and it is probable that 
numbers were thus disposed of when quite small. 
Very few dead were detected. The Rainbow fry 
on the other hand were always healthy while in 
the troughs, an admixture of earth every few days 
to the sand at the bottom of the troughs seeming 
to neutralise the ill efiects of the pollution of the 
water arising from the decay of food which had 
not been eaten. In the stewponds, too, they did 
not fight like the Brown trout, nor are they such 
depraved cannibals. 
A fissure occurred in the bottom of stewpond 
E, through which may fry escaped into the small 
stream adjoining it, where they were .seen work- 
ing their way down to the river. One thousand 
fry had been placed in this pond, but when 
drawn only 53 were left.

This pond was probably too crowded. Six 
were puB back ; all the rest were pub into the 
Nuwara Eliya river. 
There were three very small fry which have 
not grown at all since they were pub in April, 
these have been returned to the troughs.
