652 Report on the Trials of Implements at Bedford. 



manner to that described in Class XIX., and passing through chain-cups into two 

 coulters. The seed is placed in an upper seed-box, r, and falls from it into the 

 lower seed-box G, from which it is raised by a revolving disc, H, with attached 

 cups ; being thus thrown into hoppers and passing down through the chain- 

 cups I, to the seed-coulters k. Both manure and seed coulters are attached 

 to a common lever, thus again differing from Coultas's drill ; this lever has 

 its fulcrum on the concave roller-axle. The concave rollers, m, precede the 

 manure coulters, and are placed on a common axle, upon which they move 

 laterally to suit themselves to the ridges ; this axle is attached to a weighted 

 lever, n, which has its fulcrum on, and is attached in front to, the stay-bar o. 

 The seed-covering roller, p, follows up, having its frame attached on each 

 side to the concave roller lever. The box is levelled by a rack and pinion and 

 crank-handle behind. The coulters are raised by a wooden roller and chains. 



This implement also made good work, although, of course, the mode 

 of distributing the manure is not so good as that of the notched barrel : the 

 concave rollers were also not so deep and wide as in the last-described drill, 

 and consequently did not leave the ridge quite so loose. Its price is moderate, 

 being 15Z. 10s. 



No. 604. W. S. TJnderliill, of Neivport, Salojy. — This drill sows four ridges 

 at one time. The frame is carried on two wrought-iron wheels of 3 ft. 6 in. 

 fliameter, which are adjustable. The concave rollers may be set to any width 

 of ridge, and they may be raised by a winding apparatus simultaneously with 

 the coulters. I'he delivering cups are driven by means of a strap running 

 on a cone pulley, with different speeds for regulating the quantity of seed 

 sown. The seed is covered by rollers, which follow up. When sowing on 

 the flat the concave rollers may be removed. The price of this drill is 101. 10s. 

 Only one horse was attached to this implement in the trial, and worked it 

 freely. 



First Prize of 107. to J. Coultas (2796), of Grantham. 



Second Prize of 5/. to E. & J. Beeves and Son (1588), of Bratton, Westbury, 



For Table VII., Drills for Turnips, &c., on the Ridge, see p. 651. 



Class VII. Drills for Turnips and other Roots on the Ridge, 

 without Manure Box. — There were twenty entries, and twelve 

 of these machines were tried. The greater part of them were 

 furnished with concave rollers, the concavity of which was in 

 most cases too shallow and too narrow, thus causing the drills to 

 be too much pressed. 



No. 364. J. D. Snowden, of Doncaster. —The seed-box is provided with a 

 water-tight lid, and has three divisions in it, forming two compartments for 

 mangold wurzels in the centre, and two turnip-seed coraj^artments at the sides. 

 The seed-box is hung upon two pivots, and may be levelled in going up or down 

 hill by a handle at the side. The seed is raised from the seed-box by seed- 

 cups attached to a revolving barrel, which gears directly with the driving- 

 wheels. In changing the cog-wheels for sowing different quantities of seed, 

 the whole box is moved either up or down an inclined slide, upon which the 

 ends of the seed-box rest. 



The weight of the machine is carried by a pair of driving-wheels, which may 

 be either left on the machine or taken off, to suit the class of soil upon which 

 it may be working. The two concave rollers fit loosely on their axle, and are . 

 free to move laterally, so as to suit themselves to the ridges ; they are deep 

 and wide, and leave the sides of the drill in a loose condition. The roller
