have been sent to these at any: time (till lately, when some were sent to the 
Lee), yet these rivers are full of trout! As to the growth of these trout I 
may give the following facts: 4n December, 1879, 1 caught trout in the 
Oamarama weighing dlbs. each. I also hooked and played for half-an-hour 
(im company with Mr. J. A. Connell) a trout which I know must have 
weighed about 8lbs., but which was lost in netting. Trout were first put 
into this stream in 1875. One of the young Messrs. Grieves of Rocklands 
station, in February or March, 1880, caught a trout in the Upper Taieri 
which weighed 20lbs. ; and Mr. John Roberts informs me that his shepherds 
have seen them 30lbs. weight, and have caught and weighed them a good 
deal over 20lbs. Trout were first put into this river in 1870. Now sup- 
posing the dlb. and 20lb. fish to be survivors of the original stock in these 
two rivers, their yearly growth shows an increase at the rate of 14lb. and 
2lbs. respectively! This is a wonderful rate, and shows that at the present 
time there must be abundant and suitable food in the two streams I have 
selected for examples. (See specimen of atrout, pl. XII). In my previous 
paper already alluded to, I stated that I found the rate of growth from 
llb. to 23lbs., according to the stream the specimens were taken from. 
Salmo umbla (the charr).—Of this fish 1,000 ova were presented to the 
Otago society, and arrived in the ‘‘ Timaru” in April, 1875. Of these, 800 
hatched out at the ponds. From a growth on the umbilical bag many died, 
and of the twelve left at last, the whole lot escaped, and have disappeared 
in the Opoho Creek. 
The English salmon (Salmo salar) was successfully introduced to Otago 
in 1868, by the Provincial Government. The ova came out in the “Celestial 
Queen,” having been taken from Tweed and Tay salmon, Severn Salmon, 
and Irish salmon. Messrs. Youl and Ramsbottom appear to have had most 
to do in England with the collection and despatch of these ova—numbering 
200,000. The ship got to Port Chalmers on 2nd May, 1868, after a very 
long passage of 107 days; the ova, together with those of sea trout, brown 
trout, and Salmo umbla (the charr), and some live gudgeon, carp, and tench, 
with some English oysters, having been put under the charge of Mr. Dawbin. 
The live fish all died on board, and the ova of the fish just mentioned, 
excepting those of the salmon, appear all to have diedalso. (Of the oysters 
two only survived, and these were given to Mr. Seaton, Portobello, to plant 
in the bay). Thenumbers shipped were, sea trout, 1,500 ova ; brown trout, 
1,500 ; and Salmo unbla, 6,000. The trout ova were along with those of 
the Salmo wmbla given to the Acclimatization Society to hatch out at Opoho; 
but, though every care was taken, they all died. The salmon and sea trout 
ova were sent round by sea to the breeding ponds erected at that time on 
the Waiwera stream, and all arrived safely. Mr. Dawbin put about 40,000
