The study of Natural History is perhaps as little followed in this neighbourhood as in any part of the kingdom, notwithstanding the facilities which are offered. Our flora is beautiful, varied, and possesses many rare plants, yet I only know of two herbaria; the birds are abundant, yet there is but one collector of them; and as for insects, although I frequently take what I consider rare species, yet I cannot find an entomologist in the whole district, or I would send them to him. In conclusion, allow me to say, that the leisure hours a somewhat busy life has enabled me to spend in these pursuits, have been some of the happiest of my existence, and have awakened and cherished such an admiration of nature and such a love for the country and its scenes, as I think can never be appreciated by the inhabitants of large towns, and which I cannot describe so well as in the words of one of my friends in a beautiful apostrophe to England, when leaving it--never to return: [11]-- "To thee Whose fields first fed my childish fantasy, Whose mountains were my boyhood's wild delight, Whose rocks, and woods, and torrents were to me The food of my soul's youthful appetite; Were music to my ear--a blessing to my sight." * * * * * THE ROOK SERVICEABLE TO MAN.--PREJUDICE AGAINST IT. A strong prejudice is felt by many persons against Rooks, on account of their destroying grain and potatoes, and so far is this prejudice carried, that I know persons who offer a reward for every Rook that is killed on their land; yet so mistaken do I deem them as to consider that no living creature is so serviceable to the farmer as the Rook, except his own live stock. In the neighbourhood of my native place is a rookery belonging to William Vavasour Esq., of Weston in Wharfdale, in which it is estimated there are 10,000 Rooks, that 1 lb. of food a week is a very moderate allowance for each bird, and that nine-tenths of such food consists of worms, insects, and their larvae: for although they do considerable damage to the crops for a few weeks in seed-time and harvest, particularly in backward seasons, yet a very large proportion of their food, even at these times, consists of insects and worms, which (if we except a few acorns, walnuts, and potatoes in autumn) at all other times form the whole of their subsistence.
