there liberated, only 200 being lost en route. Two cans, of the capacity of 
six gallons each, were used, and these put inside larger ones, the space 
between filled with water, the temperature of which was kept low by ice. 
Blood was used to feed the fish from the first. Describing the liberation of 
these whitefish, Mr. Farr says, “looking after them for a few seconds, we 
noticed that they took a spiral course to the depth of about eight inches, then 
dived suddenly downwards, and were lost to sight in the deep azure water.” 
‘““The temperature of the water at the surface was 60°, and at 50 feet it 
was 59°.” Of other fish, I find that perch were obtained from Hobart 
Town prior to 1877, but owing to their not thriving in the gardens, it was 
determined to turn them out in the Heathcote river. Tench, also goldjish, 
were obtained and reared; 20 of the former and 26 of the latter being in 
the society’s possession in 1879. 
Otago Acclimatization Society. 
This society, which was founded in January, 1864, devoted its efforts 
for some years to procuring English insectivorous and song birds, wherein 
great success was attained. But in 1868 it sent its manager, Mr. Clifford, 
to Tasmania, who got from the Salmon Commissioners there, 800 ova of the 
trout (Salmo fario) as mentioned in my paper on Brown Trout, read before 
this Institute in July, 1878.* A subsequent lot of 1000 was obtained in the 
following year from the same source, and both were very successfully 
_latched at the society’s ponds at Opoho, by or under the immediate care of 
Mr, Clifford ; 720 of the former, and nearly all the latter, being hatched 
out. In July, 1870, Mr. Clifford brought from Tasmania fully 1000 ova of 
brown trout, and 140 ova of the sea-trout, and successfully hatched out 
at the society’s ponds every ovum. No such feat had ever before been 
achieved in fish-culture, so far as I have read or seen. These young trout 
formed the original stock, from which most of the streams in Otago may 
now be said to be stocked in measure.* I should, however, mention here 
that a previous lot of 400 ova brought from Tasmania for the Otago society, 
in September, 1867, by Mr. Johnson, Curator to the Canterbury Acclima- 
tization Society, proved to be all dead on arrival in Dunedin. The original 
trout ova from England, brought successfully to Tasmania, were obtained 
from the river Weycombe, Buckinghamshire, and the Wey and Itchen, 
Hampshire. Our brown trout are descendants of these, but I have not 
been able to trace the identity further, nor to find out more than that all 
the ova from the above three English streams did not hatch out equally 
Well in Tasmania.

Trout in Otago,” “Trans. N.Z, Inst.,” vol, xi., p. 208, But nearly every river and 
stream has received some,
