I^astly, a larger quantity of chaff is thus obtained ; and, though too great a stock of straw may be produced, for immediate consumption, yet if such article be closely and carefully stacked, it will not be easily in- jured by keepizig. THREAD, a slender twist manufadured by combining the fibres of flax, hemp, cotton, silk; or other vegetable oi* animal sub- stances J the primary operation of which is called SnxNiNG. There are various kinds of this article, such as silk, linen, and cotton thread : the most extensive manufaAory for the last mentioned sort, in this country, is established at Paisley, near Glasgow j which, however, is inadequate to supply the market. — Hence, considerable quantities of this commodity are annually imported, and are subjeft to various duties. Thus, Bruges thread pays the sum of lOs. 10|d. per doz. lbs. ; Cross-how thread, i6s. lid. per 100 lbs. ; Outnal thread, 19s. 5|d, per 12 lbs. j Pack thread, 14s, 6|d. for every lOOlbs.j lister's thread, 3s. per lb. j and IVhited-hroicm thread, ips.Sfd. per 12lbs.— By the 7 and 8 Will.

The Armeria, Commok Thrift; Sea-gilliflower ; or Sea-cushion, which is perennial; grows in meadows, and on rocks near the sea-coast; where itflowera in the months of May and June. When in full blossom, it presents a beautiful sight in pasture-grounds j on which account, it is likewise of- ten planted in gardens, as an edg- ing for borders. The Sea-gilliflower forming whole swards, or tnfts of grassy, solid, and smooth leaves, its cul- ture is much recommended in loose sands, which are thus speedily con- solidated : the naked stalk, in ge- neral, attains only the height of 6 inches. — The plant is eaten by horses and goats, but refused by sheep. THRIPS, a genus of insea* comprising 1 1 species, that are va- riously named, according to the trees which they infest. These vermin aie extremely minute; having a small slender body, and a rostrum, or beak, which is scarcely percep- tible to the naked eye : lliey are very pernicious to fruit-trees, at- tacking both the leaves and fruit ; but may be extirpated by resorting to the method already pointed out, vol. ii. pp. 21, and 22.
