DRILL MACHINES.

covered by a lid, and thus screened from wind or rain. Tlie same machine is easily 



transformed into a cultivator, horse hoe (Jig. 339.), scarifier, or grubber, all which 



operations it perfoi-ms exceedingly well ; 

 and by substituting a corn-rake, stubble- 

 rake, or quitch-rake, for the beam of 

 coulters, or hoes (a), it will rake corn-stub- 

 bles, or clean lands of root weeds. When 

 corn is to be sown in rows, and the intervals 

 hoed or stirred, we scarcely know a machine 

 superior to this one ; and from being long in 

 a course of manufacture, few can be made 

 so cheap. But these advantages, though 

 considerable in the process of drilling, are 

 nothing, when compared with those which 

 arise from the use of the horse hoe ; with 

 which from eight to ten acres of land may 

 be hoed in one day, with one man, a boy, 

 and one horse, at a trifling expense, in a style 



far superior to, and more effectual than, any hand-hoeing whatever; also at times and 



seasons when it is impossible for the hand-hoe to be used at all. 



2680. The Norfolk drill, or improved lever drill {fg- 340.), is a corn drill on a larger 



scale than Cooke's, as it sows a breadth of nine feet at once : it is chiefly used in the light 



soils of Norfolk and Suffolk as being more expeditious than Cooke's, but it also costs 



about double the sum. 



2681. Cookers three-row corn drill is the large machine in a diminutive form, and is 

 exceedingly convenient for small demesne farms where great neatness is attended to. It 

 can be used as a cultivator, hoe, rake, &c., like the other. 



2682. Morton's improved grain drill-machine {Jig' 341.) is decidedly the simplest and 



best of corn drills. In 

 this machine three 

 hoppers are included 

 in one box, the seed 

 escaping out of all the 

 three by the revolution 

 of three seed cylin- 

 ders upon one axle ; 

 and drills of different 

 breadths are produced 

 simply by the shifting 

 of a nut, that fixes a 

 screw moving in a 



groove in the under-frame, by which the distance between the two outside conductors and
