Wharfe it is the constant practice of the angler to catch Trout
through the winter with very minute roe in them, and in high
condition with the worm and Salmon roe, and also with night lines.
In fact, one of the fishermen has frequently remarked to me that
he occasionally caught dishes of Trout with the fly in January,
and in finer condition, than he has found them in April, which he
accounted for by saying that the spawned fish (Kelts) of that
season had not begun to rise freely at the fly at the former
period, but they had at the latter, so that his pannier contained
as many Kelts as fresh fish. Another reason has just occurred to
me: it is, that in January the spawned fish will still be in the
small brooks in which they are so fond of breeding, and of course
the bulk of the fish remaining in the river at that time would be
fish in good season.

As it is some years since I acquired this information, or at least
a part of it, I felt afraid of giving it incorrectly; and I
therefore addressed a letter to a friend living on the banks of
the Wharfe, requesting him to send me all the information in his
possession on this subject, that derived from his own observations,
as well as that collected from others. He has since the above was
written sent me the following reply:--"I have seen Robinson (one
of the best anglers and fly makers between Cornwall and Caithness),
and have had some conversation with him on the subject of Salmon,
&c. He is of opinion that the spawn of the Salmon remains five
months in the gravel before hatching; he examined the spawn in
April, and found the young fry alive in the eggs, and Ingham,
another angler, took some home and kept one of the Smolts two or
three months. I have subsequently seen Ingham, and he has given me
the same account. All the fishermen here are of opinion that the
