COR rious albuminous and gelatinous matters employed tor clarifying li- quors , hnve already beeu stated ; bat, as these are not in every case sufficiently powerful to precipitate all feculent particles, the following method of purifying Cydek, de- serves notice : — Let two handfuls of marie be reduced to a coarse powder, and thrown into the press- ing tub : in a short time, the ex- traneous matters will sink to the bottom of the vessel ; and the li- quor tnay the;i be drawn off per- feiftly transpnrent. COCK's-FOOT-GRASS.— Tliis vegetable is propagated by so^A'ing its seed in moist pastures, and marshy situations, Althongh its culture is at present very limited ; yet as it grows with uncommon rapidity, and withstands the se- verest droughts, when almost every other plant is scorched, we anxi- ously recommend its culture to the attention of farmers. CORD.— In June, 1801, a pa- tent was granted to Mr. William Chapman, for the application of certain substances designed to pre- serve cordage ; and which, being either with difficulty soluble, or totally insoluble in water, tend to render such ropes more durable, than has hitherto been practicable. 'I'he usual method adopted for this purpose, consists in boiling t^r alone, till it be inspissated to a proper con- sistence ; but Mr. C. proposes to boil the tar in two or three different ■waters, till it be divested of its acid, and all the mucilaginous parti- cles ; wiiich, by the common pro- cess, remain in the liquid prepara- tion ; and, by their speedy ten- dency to decomposition, frequent- ly contribute to the decay of the ropes, at an earlier period than . would nattirall}' take place without COR [4^1 such practice. He therefore adds a due proportion of suet, tallow, or any fixed oil, that has been de- prived of extraneous matters, by similar boiling. CORN. — A new metliod of pre- serving this valuable grain, is the following : Let a hollow cane or tube, about 3 feet 9 inches in length, be provided ; tnpcring gradually to a point downwards, in order that it may be more easily thrust to tiic bottom of the sack. About 150 holes, one-eighth of an inch in dia- meter, must be made on each side of such hollow cylinder, to the height of about 2 feet 10 inches fpom the bottom ; and, in order to regulate the perforatiorv, it will be advisable to wind a pack-thread round the stick, in a spiral form; so that the holes may be about half an inch apart at the bottom, and be gradually at greater distances as they appw^ach the top; being then one inch above each other ; by which expedient a due propor- tion of air will be conveyed to the, lower part of the corn. To the upper extremity of the cane, there should be fixed a leather pipe, 1() inches in length, and distended by means of two yards of spiral wirrt coiled up in it : to the upper end of such tube, a wooden fauset is to be fitted, for introducing info it the nozzle of a pair of belWws, in order to ventilate the whole sack. If grain, when first deposited, be thus aired every second or third day, for 10 or 15 minutes, all moisture will in a short time be dissipated, and the corn will aftei- wards remain dry and sweet in the sacks, with very little additional trouble. — This simple pr36tice may- be advantageously adopted for the preservation of every kind of seeds audgrain, excepting ^a;7e^i which, if
