We have here a work of great beauty in a pictorial and typographical point of view, and one which abounds with practical information regarding the bolder branches of the "gentle art." Mr Scrope conveys to us, in an agreeable and lively manner, the results of his more than twenty years' experience as an angler in our great border river; and having now successfully illustrated, both with pen and pencil, two of the most exciting of all sporting recreations--deer-stalking and salmon-fishing--he may henceforward repose himself upon the mountain-side, or by the murmuring waters, with the happy consciousness of having not only followed the bent of his own inclinations, but contributed to the amusement and instruction of a numerous class of his fellow creatures. The present volume consists of no dry didactic dissertations on an art unteachable by written rules, and in which, without long and often dear-bought experience, neither precept nor example will avail; but it contains a sufficiency of sagacious practical advice, and is enlivened by the narration of numerous angling adventures, which bring out, with force and spirit, the essential character of the sport in question. Great advances have been recently made in our knowledge of the sea-going _Salmonidæ_. Indeed, all the leading facts of primary importance in the history of their first development and final growth are now distinctly known, and have lately been laid before the public in the form both of original memoirs in our scientific journals, and the transactions of learned societies, and of more popular abstracts in various literary works. We ourselves discussed the subject in this Magazine, with our accustomed clearness, a couple of months ago; and we shall therefore not here enter into the now no longer vexed question of the nature of parr and smolts,--all doubt and disputation regarding the actual origin and family alliance of these fry, their descent from and eventual conversion into grilse and salmon, being finally set at rest to the satisfaction of every reasonable and properly instructed mind. We consider it, however, as a good proof of the natural sagacity and observant disposition of our present author, that he should have come to the same conclusion several years ago, regarding the habits and history of salmon-fry, as that so successfully demonstrated by Mr Shaw. Mr Scrope dwells with no unbecoming pertinacity on this point; but he shows historically, while fully admitting the importance and originality of that ingenious observer's experimental proceedings, that he had, in the course of his own private correspondence and conversation, called the attention of Mr Kennedy of Dunure as a legislator, and of Sir David Brewster as a skilled interpreter of natural phenomena, to various facts corresponding to those which have been since so skilfully detailed by Mr Shaw.
