The annual festival called Arbor Day, established in this country for the promotion of tree-planting, has, unfortunately, been turned over exclusively to the public schools, whereas it ought to be observed also by the churches, lodges, political clubs, and women's clubs. At all events, tree-planting should go on constantly, and should everywhere accompany the campaign for the preservation of street trees. We may well remember that as a rough, general rule, only one tree out of every twenty planted ever comes to maturity. Let us, therefore, plant liberally. In rural and semi-rural communities everywhere, it is a custom to secure from the woods and pastures those trees needed for street and house-lot planting. Where stock is collected from the wild in this way, it is best to take the trees from the open pasture—or from recently cultivated land, where possible. Effort should be made also to select those which have grown on rich, well-drained soil. The theory that trees taken from the forest will be more hardy, runs quite opposite to the fact. Indeed, the best plan is everywhere to buy young trees from nurseries. Nursery trees have clean, symmetrical tops, and are likely to have a hundred times more good rootage than trees taken from the field. Everything is in favor of the nursery-grown tree, except the price; however, very often the expense of digging and bringing in a half-dozen good-sized maples from the woods is greater than the cost of better trees of like size from the most expensive nursery in the country. Arbor Day is not necessarily the best day for tree-planting, especially in the matter of big trees for streets, school grounds, and public places. The experts prefer to handle such trees in mid-winter; they do this even in sections where the ground freezes to a depth of two or three feet; in fact, it is considered the height of good practice to take up the tree from its place, accompanied by a huge block of frozen earth. Evergreen trees, such as pines and spruces, may be handled very successfully in August, and this season is widely chosen for the purpose by knowing treemen. Many tree-lovers make the mistake of crowding their small private grounds with their pets. If one has only a city lot thirty feet wide by a hundred feet deep, he cannot grow a large forest. One or two large trees will be all such a place can reasonably support; any more will make the premises too crowded. The trees themselves will suffer, and, besides that, there will be no opportunity to view them. There will be no room for a flower garden, and no lawn for any purpose.
