The foliage of trees and plants, by its amazing profusion, variety, and beauty, must ever have been, as it is now, a subject of admiration and delight, is perhaps full as deserving of notice, and at times even more to be regarded, than the blossoms which accompany it. Let us take only one yard square upon the first verdant ditch-bank in spring, and the variation of form and character which will there be presented may probably exceed general imagination; but the object of all this extraordinary diversity is concealed, with the many other mysteries of creation: yet we have such an ascendant thirst for information upon the causes and nature of the things about us, as to render it an apparent inherent principle of the mind, inducing it to gratitude and love. From information in all the works of Providence arises, as a necessary consequence, admiration, and an exalted sense of supreme intelligence and goodness. Without the desire of knowing the designs and processes of things, no investigation would be bestowed, and we should remain in ignorance of all but the bare facts, and gross perceptions of creation; nor can it be questioned but that the more extensive our acquaintance is with the objects of Providence, in such proportions must our convictions be of his justice, wisdom, and power. The great utility of foliage, and its agency in accomplishing the requirements of the plant and its products, are well known; and we can form some comprehension of the vast supply that is required by a tree, when we view its foliage, each leaf being employed in receiving and transmitting gases from the air in certain proportions to the plant: these great operations having been effected during the summer months, and this agency of the leaves finished, they fall to the ground, not as a useless encumbrance, but to convey a large portion of fresh soil peculiarly fitted for the nutriment of vegetation. Should they remain in any quantity beneath the tree, they appear to be injurious to the smaller herbage, but they are more generally dispersed as they part from the sprays by the gales of autumn, which whirl them along in crowds to the hedges, trenches, and ditches around: here they accumulate and decay, furnishing, in conjunction with other vegetable decompositions, a very nutritive earth, as is manifest by the wild plants growing in those situations, for notwithstanding all the obstructions of shade, thorns, and briers, they are generally found in great luxuriance or health. This earth in time crumbled by frosts, and washed by rains into the ditches from the banks, becomes accumulated there, and we collect it, compost it with other matters, and use it as a beneficial dressing for our cultivated lands: many of these leaves, however, remain near the tree, and soon communicate their virtues to the herbage: some are consumed by natural consequences, others are attacked by small fungi, which break their surfaces, admit moisture, and facilitate decay; the worm now
