"The river poplaris found on the banks of rivers and brooks and in wet places, and is a noble and graceful tree. The trunk is light gray in color, and the young trees have a smooth, leather-like bark. The broad leaves, of a very rich green, grow on stems nearly as long as themselves, and the flowering aments are of a light-red color. The leaf-stalks and young branches are also brightly tinted. Another of these trees has a very singular name: it is called the necklace poplar." [Illustration: LOMBARDY POPLAR.] "Do the flowers grow like real necklaces?" asked Clara. "Not quite," replied her governess, "but the reason given is something like it. The tree is so called from the resemblance of the long ament, before opening, to the beads of a necklace. In Europe it is known as the Swiss poplar and the black Italian poplar. Its timber is much valued there for building. There are also the black poplar and that queer, stiff-looking tree the Lombardy poplar. Cannot one of you tell me where there are some tall, narrow trees that look almost as if they had been cut out of wood and stuck there?" "I know where there are some," said Malcolm: "right in front of Mrs. Bush's old house; and I think they're miserable-looking trees." "When old and rusty, they are not in the least cheerful," replied Miss Harson; "and it is so long since Lombardy poplars were admired that few are found except about old places. The tree is shaped like a tall spire, and in hot, calm weather drops of clear water trickle from its leaves like a slight shower of rain. It was once a favorite shade-tree, and a century ago great numbers of Lombardy poplars were planted by village waysides, in front of dwelling-houses, on the borders of public grounds, and particularly in avenues leading to houses that stand at some distance from the high-road. [Illustration: A GROUP OF POPLARS IN CASHMERE] "The poplar is found in many lands. The Lombardy poplar, as its name indicates, was brought from Italy, where it grows luxuriantly beside the orange and the myrtle; but after one of our cold winters many of its small branches will decay, and this gives it a forlorn appearance. When fresh and green, the Lombardy poplar is quite handsome. Some one wrote of it long ago: 'There is no other tree that so pleasantly adorns the sides of narrow lanes and avenues, and so neatly accommodates itself to limited enclosures. Its foliage is dense and of the liveliest verdure, making delicate music to the soft touch of every breeze. Its terebinthine odors scent the vernal gales that enter our open windows with the morning sun. Its branches, always turning upward and closely gathered together, afford a harbor to the singing-birds that make them a favorite resort, and its long, tapering spire that points to heaven gives an air of cheerfulness and religious tranquillity to village scenery.'" "I wish we had some," said Edith, "with singing-birds in 'em."
