Your sport in angling, whether top or bottom, materially depends upon
the state of the atmosphere. He who has paid some attention to the
effects of weather on fish, knows pretty accurately the extent of the
sport to be looked for, when the wind is in particular arts. An East or
N. East wind shuts out all hope of diversion, whilst a Southerly or
South West wind, is the wind of all winds for the angler. However, as
fish must feed at some time, let the wind be as it will, an angler who
is particularly in want of a few Trout, may succeed in obtaining small
ones with the fly in an East or N. East wind, provided the wind has
been in that quarter some days, and there is feed on the water. Any
sudden change in the wind affects the fish, and they will sometimes
give over, or begin to feed, on such changes taking place, just as it
happens to veer into the wrong or right quarter. After white frosts in
the Spring of the year, you need not expect much, if any sport. Frosty
nights with bright sunny days following, accompanied with East or N.
East winds, are precisely those sort of days, when a man had better
refrain altogether from attempting to take fish with the fly, or with
any kind of bait. During the Summer months, the colder the wind blows,
the better sport you will have with the artificial fly. On cold stormy
days in Spring, with wind West or N. West, accompanied with heavy snow,
rain, or hail showers, good fish are usually roving about, and then
your sport is of the best. Either in Spring, or Summer,
"With a Southerly wind, and a cloudy sky,
The angler may venture his luck to try."
