They run through cultivated country, with meadows or cornfields, woods or copses, and rarely far through open, unenclosed land. A stranger, and without permission, would often find it difficult to walk half a mile along the bank of such a stream as this. Consequently, if it is desired to preserve it, the riparian owners can do so to the utmost, and the water-fowl considered injurious to fish can as easily be kept down. It is different in the north, for instance, where the streams have a background of moors, mountains, tarns, and lakes. In these their fastnesses birds find some security. From the coast they are also recruited; while on our southern coasts it is a source of lament that wild-fowl are not nearly so plentiful as formerly. Of course in winter it often happens that a flock of wild-fowl alight in passing; but how long do they stay? The real question is, how many breed? Where trout are carefully preserved, very few indeed; so that it is evident trout are making as much difference as the pheasants. Trout preservation has become much more extended since the fish has been studied and found to be easily bred. Advertisements are even put forward recommending people to keep trout instead of poultry, since they can be managed with certainty. It seems reasonable, therefore, to suppose that the influence of trout on wild creatures will continue to extend for some time yet. Already where trout preservation has been carefully carried out it has produced a visible impression upon their ranks. In ten years, if it were abandoned, most of these creatures would be plentiful again on the waters from which they have been driven; I should myself be very glad to see many of them back again. But if preservation has excluded many creatures, it has also saved many. Badgers, in all probability, would be extinct--really extinct, like the wolf--were it not for the seclusion of covers. Without the protection which hunting affords them, foxes would certainly have disappeared. The stag and fallow-deer are other examples; so, too, the wild white cattle maintained in a few parks. In a measure the rook owes its existence to protection; for although naturalists have pointed out its usefulness, the rook is no favourite with agriculturists. Woodcocks, again, are protected, and are said to have increased, though it is open to question if their increased numbers may not be due to other causes. Cultivation banishes wild geese and snipe, but adds to the numbers of small birds, I fancy, and very probably to the number of mice. When the country was three-fourths champaign--open, unenclosed, and uncultivated--it cannot be supposed that so many grain-eating birds found sustenance as now. The subject is capable of much development Enough, however, has been said to show that Nature at present is under artificial restraints; but her excluded creatures are for the most part ready to return if ever those restraints are removed.
