shed. The grain falls out on the right side, and is elevated 

 through a wooden tube (elevator) by a series of tin cups attached 

 to a leather belt kept revolving while the mill is at work. The 

 grain falls from this elevator into the second winnowing machine, 

 and then into the third in the dressing room. Any unthreshed 

 ears of grain that may have passed through the mill, fall to the 

 left of the first winnowing machine, and by another elevator 

 are brought up, and falling on the grain on the feeding board, 

 are passed through the mill again and again. 



A governor acts on a piece of sheet iron in the side opening 

 of the fanners. When the speed of the fanners is fast, this piece 

 of metal closes in, and thus diminishes the blast ; when the 

 speed is slow, it opens out and presents no obstruction to the 

 ingress of the air. 



The three fixed fanners described turn out the grain pretty 

 clean ; but for seed and other special purposes, Hornsby's admi- 

 rable fanners have been recently purchased. This machine 

 seems all that is to be desired. The dimensions are — length, 

 5 feet 4 inches ; width, 2 feet 6 inches ; height, 4 feet 3 inches ; 

 do. to top of hopper, 5 feet 6 inches. So far there has been no 

 occasion to work the toothed cylinder, kept revolving amongst 

 the descending grain, which forms so novel a feature in this 

 machine. 



Over the boiler is a kiln for preparing grain, <fcc., for the 

 mill. The grain is introduced into the kiln, from the barn loft, 

 through a sluice in the wall ; and when kiln-dried it is removed 

 into a sack in the corn room, through another sluice. The kiln 

 consists of thirty plates, and seven malleable iron " wheeps " ; 

 the cost of which, including fitting, was XIO 5s. . 



The stack-yard is a spacious area, walled in. Metal stands 

 are used for the stacks. The pillars are cast-iron, and covered 

 with caps, the convex side downwards. The horizontal bars 

 are made of wrought iron or wood. 



The liquid manure propellers are worked by the 'engine. 

 This piece of machinery is placed in a small apartment, over 

 which is the water cistern for supplying the boiler, taps in barn, 

 cock in cooking shed, &c. There are two pistons, each four 

 inches diameter and two feet stroke. It was estimated to 

 distribute 4,500 gallons per hour ; but in practice it never dis- 

 charges more than 3,000 gallons in that time. The price of
