THE second evening discourse at the Blackpool meeting of the British Association was delivered on September 15 by Capt. F. Kingdon-Ward. He said that however much we may regret some of the results of the industrialization of Britainthe destruction of forest, the urbanization of pasture land, slums, and so onour country is in some respects a vast improvement on the England of four centuries ago. It was then a colourless land, especially during the winter. Thanks to the great interest taken in horticulture and sylviculture to-day, it is that no longer. About twelve thousand species of introduced trees, shrubs and herbs are cultivated in the open nearly ten times the total number of flowering plants which occur wild. Thus the British climate must be singularly elastic, and the plants themselves highly adaptable. Probably in no other country in the world of equal area can so many alien plants be grown. Some are difficult, but more are easy, and not a few naturalize themselves.
