The poplar family, as a whole, is exuberant with vigor, and interesting more on that account than by reason of its general dignity or strength or elegance. It is well worth a little attention and study, and the consideration particularly of its bloom periods, to which I commend the tree-sense of my readers as they take the tree walks that ought to punctuate these chapters.
America has much that is unique in plant and tree growth, as one learns who sees first the collections of American plants shown with pride by acute gardeners and estate owners in England and on the European Continent. Many a citizen of our country must needs confess with some shame that his first estimation of the singular beauty of the American laurel has been born in England, where the imported plants are carefully nurtured; and the European to whom the rhododendrons of his own country and of the Himalayas are familiar is ready to exclaim in rapture at the superb effect and tropical richness of our American species, far more lusty and more truly beautiful here than the introductions which must be heavily paid for and constantly coddled.
For no trees, however, may Americans feel more pride than for our American elms and our no less American tulip, the latter miscalled tulip "poplar." Both are trees practically unique to the country, both are widespread over Eastern North America, both are thoroughly trees of the people, both attain majestic proportions, both are long-lived and able to endure much hardship without a full giving up of either beauty or dignity.
The American elm--how shall I properly speak of its exceeding grace and beauty! In any landscape it introduces an element of distinction and elegance not given by any other tree. Looking across a field at a cluster of trees, there may be a doubt as to the identity of an oak, a chestnut, a maple, an ash, but no mistake can be made in regard to an elm--it stands alone in the simple elegance of its vase-like form, while its feathery branchlets, waving in the lightest breeze, add to the refined and classic effect. I use the word "classic" advisedly, because, although apparently out of place in describing a tree, it nevertheless seems needed for the form of the American elm.
