Kelson states that "The Smith" is one of the oldest patterns used on the river Tay in Scotland, and that the original pattern is probably long lost and forgotten due to the age of the fly. Therefore the pattern given here is taken from his book "The Salmon Fly" (1895). The very same dressing is given in Hale's fine book, "How To Tie Salmon Flies", and also in J. J. Hardy's book, "Salmon Fishing".
Herbert Maxwell, in his book "Salmon & Sea trout" (1898), refers to a fly called the "Gold Smith", but this fly is a completely different pattern that was often tied in large sizes for fishing the river Thurso. Thus, it is not a Gold version of "The Smith" pattern given in the dressing details below.
