To the naturalist, the most puzzling of all questions is to define accurately the limits between instinct and reason, as the terms are commonly understood. We have long ago given up the attempt in absolute despair. Take, for example, the case of the rooks. They can distinguish Sunday from the rest of the week as accurately as any precentor, and are perfectly aware that, on that day, no gun will be levelled at them. You may make demonstrations with a stick if you please, but the rooks will not fly away. They merely retort with a caw of utter scorn. But on Monday morning the Lord of Rookwood is a changed being. He will not on any account let you within a hundred yards of him; and so excessively acute is he, that you would almost swear he scents the powder in your pocket. So is it with the roes. When wandering unarmed through a Highland wood, you are almost certain to fall in with several of these beautiful creatures, who regard you almost without alarm, and glide slowly into the shaw. They know quite well that you are not there with any murderous design, and they neither fear nor avoid you. Not so if you carry a gun. In that case, you may look long enough about you before you will descry the white spot, which is the distinguishing mark of the roe-deer. They whom you seek are lying close in the brackens, perhaps but a very few yards from you, but they will not stir till you are gone. Beating for roe is stupid work. We do not see the fun of standing for half the day in a pass waiting for a chance shot, with no other regalement for the ear than the hoarse braying of the beaters, and their everlasting shouts of “Shoo!” A much better method is that of stirring the roe with a foxhound, when he glides from thicket to thicket, in advance of his pursuer, whose clear note indicates his approach, and gives you sufficient warning. But enough on this head. We have already, in former articles, while reviewing the works of Mr St John and the Stuarts, had occasion to enter pretty fully into the subject of deer-stalking. Therefore we shall not again go over that ground, although tempted to do so by Mr Colquhoun’s admirable chapter devoted to that noble sport, in which he lays down, with great perspicuity, all the rules which ought to be observed by the stalker. To such of our readers as aspire to have their exploits chronicled in the columns of the _Inverness Courier_, (the best sporting register in Scotland,) we recommend Mr Colquhoun’s book, advising them to study it well before they venture forth into the mountains. It is true that no theory can supply the lack of practice; still, deer-stalking is eminently an art; and there are distinct rules for following it, which must not be disregarded. Mr Colquhoun is more concise than any former writer, and we prefer him, as a guide, to Mr Scrope.
