employ which, in its various grades, excludes neither the opulent nor the indigent, and teeming with boundless variety, affords an unceasing excitement to emulation without contempt or ill-will. The bouquet may be an exile now; but the revolutions of fashion will surely return this beautiful ornament to favor again. With us the nosegay yet retains its station as a decoration to our Sunday beaux; but at our spring clubs and associations it becomes an essential, indispensable appointment; a little of the spirit of rivalry seeming to animate our youths in the choice and magnitude of this adornment. The superb spike of a Brompton, or a ten weeks’ stock, long cherished in some sheltered corner for the occasion, surrounded by all the gaiety the garden can afford, till it presents a very bush of flowers, forms the appendage of their bosoms, and, with the gay knots in their hats, their best garments, and the sprightly hilarity of their looks, constitutes a pleasing village scene, and gives an hour of unencumbered felicity to common man and rural life, not yet disturbed by refinement and taste. “Oh, who can hold a fire in his hand By thinking on the frosty Caucasus?” And yet the shivering of the aspen, or poplar tree (populus tremula), in the breeze will give us the sensation of coldness, and communicate an involuntary shuddering. The construction of the foliage of this tree is peculiarly adapted for motion: a broad leaf placed upon a long footstalk, so flexile, as scarcely to be able to support the leaf in an upright posture: the upper part of this stalk, on which the play or action seems mainly to depend, is contrary to the nature of footstalks in general, being perfectly flattened, and, as an eminent botanist and esteemed gentleman, Dr. I. Stokes, observes, is placed at a right angle with the leaf, being thus peculiarly fitted to receive the impulse of every wind that blows. This stalk is furnished with three strong nerves, placed parallel, and acting in unison with each other; but towards the base the stalk becomes round, and then the nerves assume a triangular form, and constitute three distinct supports and counteractions to each other’s motions. I know no petiole with a similar conformation, or better calculated for the vibration of a leaf. The leaf-stalks of plants are very curious constructions; and the nerves and vessels contained in them, which are the vehicles of a large portion of that nourishment which plants receive through their foliage from the air, seem in general differently placed, and fitted for variety of operation. The poplar is a tree that occasions at times a great deal of trouble in our pasture lands, by the tendency which it has to extend its roots, and throw out suckers. Three or four of this species in a hedge-row, bounding a meadow in my occupation, oblige me every year that the field is mowed, by their prolificacy, to send a man with his stock-ax to remove their numerous
