Common Solomon's Seal, or Convallaria multiflora, L. is also perennial; grows in woods and thickets : and flowers in May or June. This plant is eaten by cows, goats, and sheep; it possesses the properties of the preceding, but in an inferior degree; and to which it bears so close a resemblance, that it can be distinguished only by its smaller, white flowers, tipped with green; whereas those of the former are larger, though less in number, and white, with a green line running down each segment. Sooju. See Soy. SOOT, a volatile powder, of a deep black colour, and an extremely bitter taste : it arises from burning wood, coal, or other fuel; or, more strictly speaking, from the smoke condensed, and deposited at the sides of chimnies.
Considerable quantities of soot are employed in the manufacture of sal ammoniac ; and also by dyers, for imparting a fawn colour to wool. - (See vol. ii. p. 207). But the principal advantage derived from it, is, when used as a manure for cold, moist, and clayey meadows, and pastures; as it is of a warm ameliorating nature ; affords nourishment to grass ; destroys noxious Insects ; protects the crop from chilling rains; and prevents the growth of moss. The quantity varies in different counties, from 15 to 25, and even 40 bushels per acre; but it ought to-be strewed on the land during the winter, and in calm weather, so that the subsequent vernal rains may wash it into the soil : for, if its distribution be delayed till the end of February, or the beginning of March, the great heat then evolved, will affect; the tender shoots of the grass, and occasion a temporary check to its vegetation. Some circumspection, however, is required, that the soot be genuine; as the chimneysweepers frequently mix with it finely-sifted coal-ashes ; in order to increase the bulk ; but this fraud may be easily detected, by the grittiness and uncommon weight of the soot.
