one, unless it be done under very exceptional circumstances and 
by those who understand it. 
Towards the end of August and in September, 1890, I care- 
fully turned out a number of yearlings, some of which were put 
into Loch Fern already referred to. I carefully watched the 
result of this experiment, which I conducted personally, and over 
which I took considerable pains. Early in the summer of 1892, 
some of the fish were taken running up toa pound in weight, and 
were the finest fish the loch had produced since its refilling. 
Other waters were stocked with fish from the same crop about the 
same time and later, and excellent results have in several cases 
been reported. 
Further experiments were made in 1891, and from the results 
of these and a number of subsequent experiments I am satisfied 
that the earlier in the season yearlings can be introduced into 
suitable waters the better. It is much easier to transplant them 
in November and later, but at that time the water is colder and 
there is not nearly so much food present, and by waiting until 
spring a good part of a season is lost, and more than a season as 
regards the growth of the fish. Perhaps a better way of putting 
it is, that by turning out, say, early in September, a season is 
gained as against turning out in spring. Yearlings in September 
are from two to four inches in length, whereas in spring the 
Scotch yearlings of commerce run from two and a half to five 
inches. But the fish of September out-turning are found to have 
grown considerably beyond this size in a great many instances, 
and I have had them up to nine inches by the beginning of April. 
The reasons for this to anyone practically acquainted with the 
subject are apparent, and have been already explained. 
There is yet another way of stocking waters, and though I 
refer to it last, it is by no means of the least importance. It is 
by sowing or planting “fully eyed” ova in artificial hatching 
beds, and in skilful hands is one of the best and most economical 
methods now in use. ‘Fully eyed” eggs are obtainable at such 
low rates from fish culturists that they can be sown in large 
quantities at a comparatively trifling cost. Care should be taken 
in the selection, and I prefer those which have been carefully 
incubated on glass grilles. They give better results. I have
