Report on the Trials of 
agricultural experts especially, while, its work being expe- 
ditiously and economically performedj it was ordered for further 
trial. 
Article No. 3,821, exhibited by George Stephenson, of 
Newark-on -Trent, Notts, was exactly similar to the same ex- 
hibitor's horse-machine, No. 3,820 (see page 605), but worked 
with a winch-handle instead of a horse-gear. There is no need, 
therefore, to re-describe the machine, the more so as it, unfortu- 
nately, failed in its first trial. 
The chain which is employed, as in the horse-power press, 
to draw the limbs of the toggle-joint together, was wrapped 
round a very small barrel, and took on to this at so bad an 
angle that it was no matter of surprise when, after a few surges, 
the chain in question broke. The accident was, however, 
claimed to be due to a defective link, and pennission to " repair 
damages " was accordingly given. But, on the following day, 
the chain broke again before two straw bales had been made, 
and the machine was adjudged Jiors concoiirs. This failure was 
unfortunate, because, in many respects, the press promised well, 
and was all the more regretted by the Judges since it deprived 
them of making a comparison between the "toggle" and the 
" half-toggle " principle. 
Article No. 523, exhibited by James S. Huodless, of 
Walkeringham, Gainsborough, was a vertical press, having a 
platten, forced downwards, bj^ the action of a screw and gearing, 
into a compression-box with a lateral door for the extrusion of 
the bale. 
The press is filled from the top, the platten sliding out of the way for 
the admission of the loose material. After this has been trampled, the platten 
is replaced, and acted upon, in the iirst instance, by means of a winch-handle 
without multiplication of the screw's eftect. When no more compression 
can be obtained by the direct action of the screw, the men who tend the 
machine shift over to capstan levers on the side of the machine opposite 
the winch, and impart the final pressure through gearing, which considerably 
reduces the speed of tlie platten. The latter is raised, after compression has 
been effected, by means of the winch. The bales are tied by cords in the 
usual way, and turned out, at the ground level, through the lateral door. 
The press worked slowly, turning out its first (straw) bale, 
weighing 120 lbs., in ] 7 minutes, and its second Qiaj) bale, weigh- 
ing 207 lbs., in 15 minutes. This want of speed was due, in some 
measure, to the difliculty experienced in trampling. The cross- 
head through which the compressing screw passes is close down 
upon the press-body, and is not removable, and the trampler, 
consequently, worked with his body inclined instead of upright. 
The output was small, but the density high, and the cost of 
baling considerable. Two men tended the press, but, whether
