"Skill in this fishing has a wider implication than in most others,
and from the very nature of the method there must be difficulties
unkown in either wet or dry fly.

"It makes infinitely greater demands upon your knowledge of the river
and the trout than fly or minnow fishing, both of which are more or
less long range methods. Practised at the proper season, when streams
are low and crystal clear and brillliant sunlight pours down on pool
and stickle, showing up every pebble on the bottom, worm fishing is
delicate work for the expert and tantalisingly difficult fishing for
anyone wlse. "

(from the introduction to ' Clear-water trout fishing with worm' by
Sidney Spencer, 1935)
