depth to which the shares are to penetrate the soil. BP, one of the han- 

 dles by which the machine is directed, when at work. 



No. 6. Section of an improved machine for making pot or pearl barley. 

 ABCD, represent a strong wooden frame, which carries the machinery; 

 EF, an axle, upon which is fixed the tooth wheel, No. 1, which may be 

 turned by any machine having sufficient power ; or a water-wheel may be 

 placed on the same axle, for that purpose. No. 2. represents another 

 wheel, fastened upon the axle E F, to drive the wheel No. 5, which is placed 

 on the iron spindle O P; and upon this axle the mill-stone is also fixed. 

 (See I K, in Fig. 3.) G H, represent the curb or case, that incloses the 

 mill-stone and barley, when making. No. 4. a wheel fixed upon the case 

 G H, turned by a wheel and a pinion. 'R S, are bearers, in which the case 

 G H, revolves when the machine is at work. K, a hopper, to contain the 

 rough barley. M, a spout, or pipe which conveys the barley into the case 

 at P : in the circumference of the case G H, is an opening, having a valve, 

 or shutter, which allows the barley to issue out into the spout HN, that 

 conveys it down to the trough, or mill floor. 



No. 7. Profile of the same machine. O P R S, represent a perpendicu- 

 lar frame, in which the wheel and mill-stone revolve. No. 1. represents a 

 toothed wheel, fixed upon the axle R, and may be attached, or turned, by 

 any machine driven by water, by wind, or by cattle. No. 2. a wheel, also 

 fastened upon the axle R, having teeth in the circumference to turn the 

 wheel No. 5, which is fixed on the iron spindle, or axle, that carries the 

 mill-stone ; and the case T U, which incloses the stone, and contains the bar- 

 ley. The circumference, and both sides of the case T U, are covered with 

 sheet, or plate iron, in which are small holes, that allow the dust, or small 

 refuse to pass through ; at the same time retaining the barley, till sufficient- 

 ly clear of the husk. The frame of this case is made to separate in the 

 middle at TU, and is fixed together by screw-bolts, so that it can easily be 

 placed on the mill-stone, or taken off at any time if necessary. 



The machine above described, performs the operation in a safe and pro- 

 per manner, without either breaking or cutting the grain. The advantages 

 of this process are very great. Pot-barley is a most wholesome food, and 

 is well entitled to the name of" European rice" It may be consumed in 

 the same manner as rice, either boiled with milk, or ground into meal, and 

 made into puddings. It makes excellent cakes, and mixed with wheat, in 

 a proportion of one-third, or one-fourth, it makes bread of a quality scarce- 

 ly to be distinguished from bread made entirely of wheat. It is supposed, 

 that the flour of barley is the wholesomest of any. It makes the purest 

 blood, arid is particularly calculated for bilious people. The refuse is an 

 excellent food for horses.

Description (/the Corn-Stacks, ttrith Cast-iron Pillars. 



In the stack-yard at Shaw-park, in Clackmannanshire, there are 28 stacks 

 placed on cast-metal pillars, three feet high. Each rf these stacks contains 

 1584 sheaves, which, in all, would produce 728 Scotch bolls, or 559 Eng- 

 lish quarters of barley or oats ; but that number of stacks, might contain a 

 greater quantity of grain, if necessary. 



The weight of each pillar should not exceed one half cwt., which, at 16>. 

 4tl. per cwt., is 8s. <Jcl. for each pillar; but they can be made lighter, and 

 may easily be afforded at 7s. per pillar : hence,
