brown trout. Apparently the waters in which the steelhead trout 
survive the brown trout have a somewhat higher temperature 
than the waters in which the brown trout superseded the steel- 
heads. The highest summer temperature in the snow-fed rivers 
in the south island is about fifty-five degrees. This is where the 
brown trout do not allow the steelheads to obtain a foothold. 
No definite results have followed the attempts to introduce 
the chinook salmon previous to the year 1900. At this time 
the New Zealand government took up the introduction of this 
species in a systematic way and since then-has devoted its efforts 
to one river, namely, the Waitaki. ‘This river has its source in 
three tributary streams which flow into lakes and the outflow 
from these lakes form the Waitaki, which is a stream about the 
size of the Sacramento River in California. Chinook salmon 
eggs have been imported annually since 1900 and a good per- 
centage of them have been successfully hatched. Some of the 
young fish have been held until over a year old before being 
planted. During the autums of 1904 and 1905 (month of 
April), reports came from the streams flowing into Lake Ohau 
that fish resembling salmon were spawning. The information 
was not received at headquarters until six weeks after the time 
the spawning was observed, and when a man sent out by the gov- 
ernment to investigate had arrived, the fish had disappeared. 
Fishermen have stated that fish caught at the mouth of one of 
the tributary streams during the last two years are brown trout. 
However, two of these anglers, of large experience in fishing for 
salmon in Norway, are emphatic in their statements that they 
caught salmon. 
There have been a great many importations of Atlantic sal- 
mon eggs, all obtained from England. The introduction of the 
Atlantic salmon was begun thirty years ago. In 1898 two speci- 
mens, twelve and sixteen pounds in weight, were caught by ang- 
lers and forwarded to Dr. Gunter of the British Museum, who on 
examination pronounced them to be S. salar. For the present, 
however, the attempts to acclimatize the Atlantic salmon have 
been discontinued. 
Several shipments of whitefish eggs had been made to New 
Zealand previous to 1903 and upon arriving in the country there 
was no convenience for hatching them. They were divided up
