This herb may be easily propagated : in March or April, take a quantity of slips, or cuttings, from three to four inches long ; having stripped off the lower leaves, plant them in a shady border, four inches apart. If occasionally watered in dry weather, they may be transplanted early in autumn; removing them, if possible, with balls of earth.—When they are intended for a crop, it will be requisite to set them in rows two or three feet separate, and at the distance of two feet from each other; but, if destined for the shrubbery, they should be planted singly, at proper distances.
Lavender is employed both for medicinal and domestic purposes. The flowers should be gathered in July, when the spikes being cut off close to the stem, in a dry day, and tied up in bundles, are much esteemed, not only for their grateful odour, when deposited inchests, or boxes, among linen; but chiefly for preventing the depredations of moths and other insects.—By distilling these flowers, they yield a compound spirit, which is of considerable service in palsies, vertigoes, lethargies, tremors, etc. The distilled oil possesses the power of destroying the pediculi inguinales, and other cutaneous vermin. If soft, spongy paper be dipped in this oil, and applied at night to the parts, infested with the insects, they will, according to Geoffroy, be found dead in the morning.
