The Exercises, upon which Mr. Walker has written, admitted of being inculcated by methodical rules, and acquired by a systematic routine of practice. An acquaintance with them will be found of service to youth, whatever the destination of its manhood may be; while they are essential to the formation of a frame and character fitted for the maturity likely to be devoted to the wear and tear of our hardy Rural Sports. Driving and Yachting, though neither of them strictly coming within the pale of a course of physical exercises, still are not out of place in a practical book devoted to the science of manly recreations, because each is governed by certain rules, which may be taught and acquired. It is not so with the subjects constituting the matter on which we are at present engaged. A man may out-study Zoroaster without being one whit the better qualified for winning a fifty-pound plate, hitting off the line of a fox that has been headed, or bringing down his woodcock in cover; these are arts which, being decimated, leave one part to theory and nine in favour of practice. For this cause I have made my Article on the Turf of a character more suited to the purposes of the general reader than those of the visionary theorist, who may fondly hope to meet, on page traced by mortal hands, a recipe for breeding, training, and managing an embryo winner of Derby or Leger. The Chase, however, admits of a certain code of general maxims: it has, if not limits, at all events courses better defined than those of the Turf, and to the application of them by practical men of modern experience we will at once proceed.
