There is one element in the construction of this deeply-laid scheme which requires to be considered with an especial carefulness. The structure of the fly which is to be set before the trout on whose capture we are bent is an ingredient in the transaction the importance of which must by no means be overlooked. It should of all things--and this is a point not enough considered by the makers of these little works of art--be one which looks well in the water. There are many flies sold which appear perfectly right and natural while they remain out of the water, but which, when once they are thoroughly wetted, assume an entirely different and most inferior appearance. The loose wool and feather strands, which form the body of the fly, get matted together and the whole mass of them much reduced in size; the wings cease to stand out away from the body and from each other, and the hook, owing to the reduction of the size of the fly generally, which is effected by the tightening influence of the water, is left much too bare and prominent. The best way to obviate these difficulties is to make the body of the fly somewhat fuller and more fluffy than it is intended to be, and to dress it as far down towards the bend of the hook as is compatible with symmetry of structure. The hook is sure to be conspicuous enough at best, but every pains should be taken to make it as little so as possible. We are particular about all sorts of minute considerations of colour and form; we refuse to allow of the deviation of the sixteenth of an inch from the right standard in the length of a tail, or of the faintest false shade in the colouring of a wing--in all these matters we are exact and scrupulous, and rightly so; but is it quite consistent with such close attention to detail that we should be indifferent to so remarkable a deviation from the right model as is found in the immense and conspicuous hook which protrudes beyond the body of our counterfeit insect, and which seems quite as much calculated to attract attention as any other part of the fly? Of course, to some extent, this cannot be helped, the hook being a necessity of the fisher's case, but surely it might in many instances be much more carefully concealed than it is. The fly might, for instance, be dressed not actually on the shank of the hook, but on a piece of gut or bristle attached to it and hanging loose on the hook so as almost to hide it. In putting on a worm as a bait--the worm having the advantage of being the real thing--we take the utmost pains to conceal the hook; in putting on the fly--which has the disadvantage of being not the real thing but a counterfeit--why should we not do precisely the same thing?
