cylinder, one acting on each set of notches. This was the 

 niost effective one, especially as it could distribute small as 

 well as very large quantities without in any way rubbing the 

 manure. When superphosphate, however dry it may be, is 

 rubbed, it at once becomes pasty ; so that the less it is disturbed 

 in this manner the better. 



2. As in T. Harrison's, by a smooth roller, revolving at the 

 bottom of the manure-box, with stirrers placed verticailv over 

 the top of the revolving cylinder working laterally. These 

 stirrers were effective, and the revolving smooth cylinder deli- 

 vered small quantities very well, but not such large quantities 

 as the notched cylinder. 



3. T. Harrison also exhibited a drill in which the stirrers, 

 were inclined and worked laterally, the manure being distributed 

 by a smooth roller, similar to that in the mode last described. 

 This also delivered small quantities well, but not large ones. 



4. In W. Rainforth and Son's drill. No. 3356, the manure 

 was distributed by a smooth roller, and the stirrers were placed 

 vertically, having also a vertical motion. These stirrers were 

 ineffective, sending out the manure unequally over the rollers. 



No. 2790. James Coultas, of Grantham. — The manure-box contains 5 bushels. 

 It has a door in front, which may be removed, when it is requisite, to clean 

 out the box. In the box is placed an inclined stirrer, which consists of a 

 loDgitudinal rod with a number of flat projecting teeth, and having a lateral 

 motion. 



A Chambers's manure-barrel is placed at the bottom of the manure-box, 

 and is geared off both driving-wheels so as to equalise the draught. The 

 cylindrical barrel has a number of small projections cast on it, each notch 

 carrying its own quantity from the manure-box to the trough, where it is 

 scraped off by steel scrapers, a number of which are placed side by side 

 beneath the box, one against each set of projections. The pressure of these 

 springs may be varied according to the adhesiveness of the manure. By a 

 slide the quantity to be delivered may be regulated from a small dressing 

 to a very large one. The manure is thrown into a hopper, and passes down 

 through chain cups into the coulters, these being attached to weighted inde- 

 pendent levers. 



The capacity of the upper seed-box is Si bushels, and it is provided with 

 a waterproof lid, in order to prevent any rain from entering the seed-box. 

 From this the seed passes into a lower seed-box, its flow being regulated by 

 slides. The seed is delivered by means of cups, attached on the side to 

 the circumference of the discs of a revolving barrel ; thus raising it up and 

 throwing it into hoppers. A bolster is placed between each of the discs, to 

 prevent the seed flowing from end to end in going along hill-sides. 



Each hopper has a cover which may be closed when required, so as to stop 

 delivery into any one or other of the coulters. From the coulters the seed passes 

 through two chain-cups into india-rubber seed-pipes ; these being connected 

 above to the lower chain-cups, and below to tin seed-pipes, which are in turn 

 attached to the seed-coulters at their lower end. Each seed-coulter is attached 

 to an independent lever. All the coulter-levers are aiTanged on two stay-bars ; 

 they are raised by means of a wooden roller and chains attached to it and to 

 the ends of the levers, the roller being acted on by an improved crank-
