uch a heap of filth? It would be quite impossible.

In conclusion, it seems desirable and quite necessary to say a few
words as to the priority of discovery of this process of fish
propagation. The French claim it; the Irish seem to claim it; the
Messrs. Ashworth take great credit for it; and now Salmo Salar
says he first suggested it. Allow me, as there are so many
claimants in the field, to suggest one or two more. In the year
1832, without knowing that such a thing had ever been done or even
thought of, I made some experiments on the spawning of fish and
the artificial impregnation of their ova, which I communicated to
"Loudon's Magazine of Natural History," in which they appeared.
After that came the Duke of Buccleuch's game-keeper, Shaw, whose
experiments were both satisfactory and conclusive. This was in
1836 or 1838. Then after my experiments at home, I induced Mr.
Fawkes to take up the matter in 1841, and they were resumed in
1842, and again in 1848 and 1849, both with Salmon and Trout. It
was at this period that Ramsbottom came into the field. At Mr.
Fawkes's request I instructed him in the art, and sent him to
Farnley, where he was perfectly successful; and since then, I
believe he has had more experience and been more successful than
any other propagator in the kingdom.

The principle of this system is very easily comprehended; but
success depends on many niceties of manipulation, and much
experience in judging whether the fish, both male and female, are
in the proper condition for operating upon.

This experience is not gained without much practice. This practice
Ramsbottom has in great perfection. There is no doubt the
artificial breeding of fish will be found exceedingly beneficial,
if properly carried out; and I hope to see the time when Salmo
Salar may catch half-a-dozen of his namesakes at Whitewell, any
good day in the season.

I am, Sir,
Yours very truly,
THOMAS GARNETT.

ARTIFICIAL BREEDING OF FISH--(CONTINUED).

CLITHEROE, _9th January_, 1854.

To the Editor of the "Manchester Guardian."

SIR,--As I believe that Salmo Salar is quite as desirous of
increasing the breed of Salmon as myself, the controversy between
us may be reduced to very narrow limits. He believes that Trout
eat very few of the Salmon ova, and therefore cannot do much harm.
I will just mention a few facts which make me think otherwise.
When Ramsbottom was in Galway he caught in one night twenty-five
Trout
