T EE middle - sized tree j and, as its fine leaves resemble those of the cypress, it is often cultivated in pleasure-grounds. The Germans employ it with advantage in the process of tanning ; but the ashes procured from it contain a true Glauber's salt, an earthy sea-salt, and vitriolated tartar. In the salt- petre works on the Continent, the same ashes are employed for clari- fying the mother-ley . There is another species of this shrub, the German Tamarisk, a native of that country ; and which deserves to be introduced into Bri- tain : according to Suckow, it strikes, with the addition of green vitriol, a beautiful dark-brown dye on wool, and a very bright reddish- brown colour on silk. — Its fruits are used by dyers, as a good sub- stitute for Aleppo-sails. TANNING.— In November, ISOl, a patent was granted to Mr. Francis Brewin, for an im- "J>roved method of Tanning. His process consists principally in con- solidating floaters and taps, by dravving the oozes for the vats, and handlers from the floaters, &c. But, as this contrivance is by the paten- tee described in confused, intricate terms, and can be interesting or intelligible only to tanners, we re- fer the curious reader to the l6th vol. of the "Repertory nJArts, &c. TEETH". — Various remedies have been suggested in this article, for relieving the tootk-ach, 'Yo these may be added the inseft, termed Lady- bird, or Coccinclla septem-pmiSiata, L. which, on rubbing it between the fore-finger and thumb, then applying the for- mer two or three times to the pain- ful tooth, has generally afforded telief. Lately, also, charcoal has been found of great service, both T UR [4 a as a preventive and cure ; for which purposes the cavity of a ca- rious tooth should be filled with pulverized carbon : thus, the pain will in a short time be removed. TUEIP-TREE, or Liriodendron tidipifcra, L. a native of North America, in the temperate climates of which it attains the height of from 60 to 100 feet : in colder re^ gions, it degenerates into a bush. — ^The wood of this elegant tree, while young, is white; but, at an advanced age, assumes a fine yel- low colour. It is equally useful in building light vessels, and as fuel: on account of its quick growth and easy culture, this noble plant de- serves to be reared in Britain.-^ With this view, the ripe seeds should be collefted in Oftober, carefully kept in a moist state, co- vered with leaves; and planted in the succeeding spring; as they re- quire three years to strike proper roots, TURNEP, — In Novcmbel", 1801, a patent was granted to Mr. William Jackson, for a machine or drill designed to sow turnips.— By this contrivance, turnip, rape, or similar small round seeds, may be drilled at any requisite distance: it may farther be adapted to the width of any furrow; and, by means of certain ingenious machi- nery, the seed may be deposited either under such furrow, or upon the ground, — Our limits not per- mitting us to detail the constituent parts of Mr. Jackson's drill, we can only state, that his implement unites cheapness with utility, and may be purchased for the small price of ll. lis. Gd. : hence we re- fer the reader to the l6th vol. of the " Repertory of Arts" &c. where the specification is illustrated with an engraving, G g 2 WASP,
