64 The greater summer-leafing trees 



western Europe, there can be no doubt about its fitness 

 for our climate, but as it dreads the wind, we should 

 avoid planting it in isolated lines, or as a wind-screen, 

 or on a south-east slope, and choose for it a good place 

 in hollows, at the bottoms of slopes, and within woods 

 where underwood is grown, where it can develop to the 

 full its fine and erect habit. 



And this applies also to the greater Poplars of the 

 forest, the ones we are concerned with here being the 

 Green, Black, Italian, and Canadian Poplars. 



The Lombardy Poplar. A variety of the Black Poplar, 

 like all varieties of trees, it is inferior to the wild tree 

 in health and vigour. Many trees of it are diseased, 

 especially where the situation is not well chosen for 

 them. The Lombardy Poplar is a great tree in the 

 Italian valleys like those of Aosta, and there it attains 

 a noble vigour, as it does, also, in our own valleys, for 

 the deep soil beside a river is the best for it. Of late 

 years another handsome upright Poplar has come into 

 cultivation, which looks like a variety of the White 

 Poplar, and is said to be wild in parts of Asia, much 

 the same as the Lombardy Poplar is said to be wild in 

 Asia Minor. In forest work omit both these erect forms 

 of Poplars and also all the Aspens and the nursery forms 

 of alba, and keep to the Black Italian, the Canadian, and 

 the White Poplars. 



The Eastern Plane. At first sight this classic tree, of 

 which there are many colossal examples in Eastern 

 countries, might be thought out of place among trees 

 of the Northern Forest; but it thrives even in the 

 London squares, and a tree that resists the winters of 

 London and Paris, and, worse than all, the greasy 

 smoke of Newcastle coals, may well take a place among
