Amongst the Birches are at least two desirable weeping forms in the cut-leaved (_Betula pendula Youngi_), Young’s weeping Birch, and the weeping white Birch (_B. alba pendula_), both of which are admirably adapted for lawns, even where space is restricted. The Birch will thrive on poor, light soil, and is, therefore, peculiarly suitable for planting in gravelly or rocky formations. The distinct habit of the Weeping Mountain Ash, or Rowan tree, has made it a favourite in the embellishment of small grounds, and the wealth of conspicuous fruit produces a telling effect, especially if the tree is backed up by darker foliaged trees or shrubs. There are other forms of Pyrus well worthy of attention, such as the pendulous Siberian Crab (_P. prunifolia pendula_) and _Salicifolia pendula_, the latter in particular being a distinct and graceful small-growing tree. The Weeping Mulberry (_Morus alba pendula_) is occasionally seen in good form when it is a desirable acquisition, so is the Weeping Laburnum (_L. vulgare pendulum_) and the curious and scarce _Gleditschia triacanthos excelsa pendula_. In the silver-leaved Weeping Holly we have one of the best of evergreens for confined situations; and _Cornus florida pendula_ is a strikingly beautiful tree in which the weeping habit is decidedly pronounced. Among Weeping Elms some varieties are most pronounced, but there are several others all equally worthy of culture. Of the English Elm, probably the best is _Ulmus campestris Petersii pendula_, while of the Mountain or Scotch, that known as _U. montana pendula_ is the most desirable. Weeping thorns are by no means common, but they are probably the most natural and graceful of all drooping trees of modern growth. In the flower garden at Regent’s Park is growing a beautiful specimen of this tree. Perhaps the most common of weeping trees is the Weeping Ash (_Fraxinus excelsior pendula_), and its strong, vigorous growth causes it to be employed where others would not succeed. Even in smoky localities it is quite at home, as many fine old trees throughout London clearly prove that the deleterious effects of an impure atmosphere have but little effect on its hardy constitution. It is one of the best of weeping trees for forming an arbour, and as a distinctly ornamental specimen for the park or large lawn it has few equals. Amongst coniferous trees we have several distinct and beautiful pendulous trees or shrubs, such as _Abies excelsa inverta_ and the well-known and much appreciated _A. Smithian_ or _morinda_. The pendulous Hemlock spruce (_A. Canadensis pendula_) is one of the prettiest and most natural in appearance of all weeping trees.
