sent from small brook trout in Hampshire and Buckingham- 
shire to New Zealand, have developed into 20]b. and 3801b. 
fish. But to obtain these fine breeds, great care must be taken 
in keeping the parent fish in suitable ponds; if breeders of 
different years can intermix, then the benefits of age will be 
lost. Thus it is the finest forms come from seven or eight 
year old parents, as has been ascertained at Howietoun, where 
the young, the progeny of such, are now being kept to be 
breeders in their turn, and it does not seem an unreasonable 
expectation to see in a few years such a semi-domesticated 
breed as these islands have never witnessed; and all this due 
to the enterprise of a single energetic private individual. 
Then there are the so-termed land-locked salmon, which 
might prove invaluable to upper riparian proprietors, or those 
who possess inland lakes, or where descent to the sea is rendered 
impossible from any cause. In Maine, in the United States, 
there is found a variety of the salmon which has taken ona 
lake-life, and never descends to the sea; many of the eggs 
were sent over last year to this country, and the young reared 
from them were exhibited in the Fisheries Exhibition. The 
Canadian Commissioner observed that in some of the rivers of 
the Dominion of Canada the same variety obtains. From — 
Lake Wenern, in Sweden, a few of the identical land-locked 
form were received at the Fisheries Exhibition, some of which 
weighed as much as 15lb. All these forms are merely varieties 
of the common salmon (Salmo salar,) that has altered its 
conditions of life. It has been asserted by some so-called 
authorities on fish that no salmon in our country has ever 
developed ova without first descending to the sea. Here, again, 
facts at Howietoun entirely disprove this assertion. Some young 
salmon were hatched in March, 1881, and in December, 1883, 
while still in the ponds, some females were found with ova. 
These, being bred from, will form the nucleus for a land-locked 
race, and which, after one or two generations, will be similar 
in all respects to those of Maine and Lake Wenern. As some 
(in Canada) are found in the rivers, there does not seem to be 
any reason why the same results might not be obtained in this 
country.
