Nor, because _some_ planting of wildflowers may be unobjectionable, does it follow that all such enterprises are deserving of praise. A recent announcement that the Llanberis side of Snowdon, a locality rich in British mountain flowers, was being sown by Kew experts with the seeds of a number of "Alpines" from Switzerland, was likely to be more agreeable to rock-gardeners than to mountain-lovers, who have a regard for the distinctive character of Snowdon itself, and of its native flora. A country which has allowed its finest mountain to be exploited for commercial purposes, as Snowdon has been, is perhaps hardly in a position to protest against a Welsh hillside being planted with alien Swiss flowers, and even with Chinese rhododendrons; but nevertheless such schemes are thoroughly incongruous and barbaric. What sort of mountains do we desire to have? A piece of nature, or a nursery-garden? A Snowdon, or a Snowdon-cum-Kew? Be it understood, then, that the sowing of tares is by no means recommended as a practice: all that is here urged is that a sweeping condemnation of it is not warranted by the facts, inasmuch as circumstances, not dogma, must in each case decide whether it be blameworthy, or harmless, or beneficial. And apart from common sense, there is one natural safeguard which will prevent any undue growth of wildflowers, viz. the remarkable fastidiousness of the choicer plants in regard to soil and conditions: they will flourish where it suits them to flourish, not elsewhere. Certain auxiliaries, too, Nature has in the rabbits, water-voles, and other wild animals that are herbivorous in their tastes; for it is very interesting to observe how quickly the appearance of a strange plant will attract the attention of such gourmands. I was once the owner of a sloping meadow in which there were some springs; and thinking it would be pleasant to have a water-garden I had a small pond made, into which I introduced some aquatic plants, and among them, most accommodating of all, the water-violet, which grew lustily and sent up a number of its graceful stalks with whorls of pink blossoms. But just at that time a water-vole took up his residence there, and developing a remarkable fondness for a new savour in his salads, quickly made havoc of my _Hottonia palustris_. The neighbours assured me I must trap him; but to treat a fellow-vegetarian in that way was out of the question, especially as his confidence in me was so great that he would sit nibbling my favourite aquatic, which seemed also to be _his_ favourite, while I stood within a few yards. It was clear that if the cult of the water-violet involved the killing of the water-vole it had got to be abandoned. In this way, among others, does Nature protect herself against an excessive interference on man's part with the distribution of wildflowers. XIV DALES OF DERBYSHIRE
