134 FIFTY-FIRST ANNUAL REPORT OF We might say much in praise of the maple genus, because of symmetrical and graceful trees, refreshing green or red-tinted leaves-in spring giving some of the earliest spring flowers, and painting with such brilliant colored foliage in autumn. The wood is useful in so many ways, while maple syrup and maple sugar have distinctive qualities which we all enjoy. The Sugar maple-Acer saccharum-heads the list for economic value, and is a leader among ornamental shade trees. The leaves are among the brightest showing autumn coloring. The Silver maple-Acer saccharinum-one of the soft maples, is found native generally near river banks. It makes a fine tree, more openly spreading than the Sugar maple. In some places it is badly infested with the cottony maple scale, but where free from this enemy it is well worth planting. The Red or Swamp maple-Acer rubrism- is found in our high ridges of clay soil even more plentiful than in swamps. It does not make so large a tree as either of the two species mentioned. The trees are attractive in the spring be- cause of the abundance of red flowers and in the fall the ripening leaves vie with those of the Sugar maple for brightness of color. The Box Elder-Acer negundo-makes fairly good fire wood. The Basswood-Tillia americana-called Linn in the south and Linden in Europe, gives a dense shade. The tree is symmetrical when grown in the open and is a useful street tree. The light, strong wood is useful in manufacture. Formerly the inner bark was used for the same purposes to which Raffia is now made use of. The flowers are valuable as abundant sources of honey. The wood of the White ash-Frazinus americana-is so useful it is a cause for regret that so much has in the past gone for fire- wood. It forms a shapely tree and gives good shade. The speci- mens which have been left about farm homes in the timber lands make a fine appearance. I am informed that we have also the Red ash-Fraxinus pennsylvanica-and the Green ash, which in Gray's Manual is given as F. Canceolata-a variety of the Red ash. We are also credited with the Blue ash-Fraxinus quad- rangulata. White ash certainly deserves to be more often planted. Perhaps the three other kinds are desirable. The Black ash- Fraxinus nigra-with tall trunk, not heavily branched, and with gray, flaky bark, is distinct in appearance, but not specially at- tractive. The wood furnishes good basket material and barrel hoops. It will flourish in any good soil, although found wild mostly in low ground.
