DRILL MACHLXES. 



pared, and is run along the summit 

 of the furrows. 



Fig. 2 is a much more important 

 single drill for beans, &c. It is fur- 

 nished with a circular coulter, c ; a 

 small double-moukl-board plough ; a 

 wheel, a, to regulate the depth of 

 furrow ; and an arrangement of le- 

 vers, b, by which the seed-cylinder is 

 thrown out of gearing in a moment 

 by the workman, as the barrow is 

 moving over the butts, &c. The re- 

 volving cylinder, in this case, is mo- 

 ved by an axis furnished with a cog- 

 wheel, set in motion by the wheel 

 itself. It is a very excellent ma- 



chine, and can be used to prepare 

 the soil, or on level ground, without 

 previous ploughing. 



Figs. 3 and 4 represent views of 

 a turnip drill barrow, with a contri- 

 vance for fluid manure, water, &c., 

 to be deposited at the time of sow- 

 ing. The seeds are contained in a 

 cylindrical tin can, furnished with 

 holes at proper distances, b ; this is 

 set in motion by the band running 

 from the wheel, and deposites the 

 seed in a funnel, the front part of 

 which scrapes the drill ; a is the res- 

 ervoir of fluid, which discharges its 

 contents along the tube, d, immedi- 



ately upon the seed sown ; after 

 the stream, the roller, e, serves 

 to cover the seed, and thus com- 

 pletes the operation. Figure 

 4 represents the seed cylinder, 

 funnel, and roller from behind. 

 The stream of fluid manure is 

 necessarily very fine. 



Weir's manuring one-ro70 drill 

 is figured in 5 and 6. It is a 

 great improvement on the cele- 

 brated Northumberland turnip 

 drill.
