ery place against which the sheep can ' 

 nib hiniseir becomes tainted witli the 

 poison. The sheep must be housed, 

 and shorn as closely as possible, and 

 then well washed with warm water. '. 

 An ointment composed of one part of ; 

 mercurial ointment and seven of lard, 

 or sulphur and lard, must then be pro- 

 cured, and su(;li a quantity of it as the 

 diseased parts seem to require rubbed 

 in on every second day. Every place 

 in the field and in the fold against 

 which he can possibly have rubbed j 

 himself must be well cleaned and j 

 painted before he is permitted to re- 

 turn. The cause of scab consists in 

 the presence of a minute insect or i 

 tick (^Acarus), which may be convey- j 

 ed from one sheep to another when j 

 an infected sheep comes in contact ; 

 with a sound one ; or it may be left j 

 on the rubbing-post, and entangled 

 in the wool of the next animal that 

 comes in contact with it ; or it may 

 be the product, and is too often so, 

 of disease of the part. It is of spon- 

 taneous origin, as well as the product 

 of contagion, and is called into exist- 

 ence by the derangements which our 

 neglect, or accident, or disease has 

 made in the skin. This is a view of 

 the case that should never be forgot- 

 ten by the sheep-owner. 



" Lice and Ticks will be best got 

 rid of by the application of the mer- 

 curial ointment just recommended, 

 or dipping the sheep in a decoction 

 of tobacco. 



" The Fly. — Several species of fly 

 frequently deposite their ova on the 

 wool of the sheep. If there are any 

 sore places, they are selected for the 

 habitation of the larvae. The head, 

 as the most exposed part, is the one 

 oftenest attacked, and the sheep are 

 sadly tormented by the fly and the 

 larvae. The best preservative or cure 

 is the application of a plaster compo- 

 sed of a pound of pitch and a quarter 

 of an ounce of bees' wax, spread on 

 soft leather or linen. The attack 

 may, however, be generally prevent- 

 ed by the application of a small 

 quantity of spirit of tar to the head, 

 or any bare or sore part. Two or 

 three applications of this will be suf- 



ficient for the whole of the summer, 

 and not a fly will approach a sheep 

 thus guarded."

 Pharmacopoeia. 



SHEEP-FOLD. A yard for sheep 

 to be gathered into in cold weather 

 or during night. It should be well 

 littered, and in a dry situation. Sheds 

 of slabs may be placed around, or 

 facing the south, so as to aflbrd 

 them shelter from cold. Shelter and 

 warmth during winter efTect a great 

 saving, even as much as one half of 

 the food. 



SHEEP-PENS. Enclosures made 

 by hurdles. They should be situated 

 on dry places. Tliey are convenient 

 for sorting and examining the ani- 

 mals, separating the sickly and lamb- 

 ing, &c. 



SHEEP, PERUVIAN. The al- 

 paca, or llama. See Alpaca. 



SHEEP'S SORREL. Rumex acc- 

 tosclla. A small acid weed, growing 

 in thin, poor soils. 



SHELLER, CORN. A machine 

 for removing the grain from the cob. 

 There are innumerable patents for 

 corn shcllers. The machines are of 

 two classes, either for shelling one 

 or two ears, or acting on a large quan- 

 tity. The form.er usually consists of 

 a wheel of cast iron, roughened over 

 the whole surface by knobs, which is 

 rotated against the ear placed in a 

 spring case ; by this means, theknobs, 

 grating against the ear, tear ofT the 

 seeds, and the cob is gradually push- 

 ed out of the case below : the case is 

 connected with a hopper. For larger 

 purposes, a cylinder is roughened and 

 made to rasp against the ears. F. N. 

 Smith's corn sheller seems to be the 

 most effective of the latter" kind ; it 

 is made by Hanna and Peaslee, Va- 

 latie, New-York : they will shell and 

 separate the cobs of upward of 100 

 bushels in the hour. Price $40. 



SHELL LIME. Lime procured 

 from burning shells. If well made, 

 it is excellent for agricultural purpo- 

 ses, as it contains nearly two per 

 cent, of bone earth, and is free from 

 caustic magnesia. The term lime 

 shells is used by many writers, from
