The wood is usually light and close-grained: the twigs of several species, used by basket-makers, are remark- able for their plial)ility. The bark of most of the species con- tains a peculiar vegetable principle, cal ed salicine, which, for intenaittent fevers, is nearly as serviceajle as Peruvian bark; and the down of the seeds has been manulactured into a coarse paper. Most of the species aftect wet or humid situations, being comnKjn on the immediate Ijorders of brooks and rivers, •which they fringe with a luxuriant and agreealde vegetation. The llowcrs generally precede the appearance of the leaves, and, though not beautiful, they are seen with delight, as the earliest harbingers of our northern spring. The species, more than two hundred in number, present nearly the same general form of loliage, with the margin entire or serrated; the catkins are lateral or terni'ial, and the stamens are too variable in number to admit of a classification by them; there are some with only one, a good many with two, others with three, four, five, or even nine or ten. The capsules, though small, ail'ord the best traits of specific distinction. The leaves put on various appearances, and even outlines, in the progress of their growth, and tho Willows justly rank among botanists as the most pnjtean and 4iflicult
