Tlie area of work done was, 2 acres and 8 perclies, iu 3 hours 23 minutes, or 
at the rate of G acres and 9 perches per day of 10 hours. 
The average depth was only 4 J inclies ; the weight per superficial yard 
318 pounds, tjivinn- 687 tons per acre, and -tlG tons moved per hour. 
The tons moved per hour per nominal horse-power were only 34^, hut this 
small result is in part due to the fact tliat the engine {12 horse-power) was iu 
excess of the work it had to do, and was worked at much less pressure than 
other engines. 
Lot 4. — Messrs. Fowler and Co.'s 8-horse Clip-drum Engine, with tra- 
velling disc-anchor, working one of their 5-tine cultivators,. has been so fully 
described in'the other class," that we need only remark that the time occupied 
in moving to the field was 5i minutes, preparing for work, 29 minutes. _ 
For the area cultivated, the time occupied in such cultivation, the weight of 
earth moved, &c., see the record already given in respect of this engine in 
Class I. 
The number of tons moved per hour per horse-power was greater in the 
case of this clip-drum engine than in that of any other system tried, whether 
in Class I. or in Class II. This result corroborates the soundness of the views 
we entertained as to the importance of utihsing the strain on the tail-rope. 
We have not, however, awarded a prize to this engine in Class II., because 
wc consider its cost — 648?., or, with the implements, lOSl. — renders it unfit to 
compete successfully in the small-occupation class. 
Lot 5. — Edward" Hayes, Stoney Stratford, Bucks, exhibited his 10-horsc 
Portable Engine and Patent Windlass, working W. Smith's combined culti- 
vator. 
The windlass is ingenious, and deserves notice. It consists of a frame on 
4 wheels, provided with a main shaft, in the centre of which is mounted a 
loose pulley, driven by an indiarubber strap from the engine. On each side of 
this central pulley is placed another pulley, also loose upon the shaft, having a 
spur-pinion attached to it. Each of these pinions gears into a pinion on a 
se])arate short shaft, turning in a bearing on the under side of the drum. The 
other ends of these short shafts are provided with other spur-wheels, gearing 
into internal wheels attached to the winding-drums, which are also loose upon 
the shaft ; so that if the driving-strap is caused to run on one of the side 
pulleys, the pinion attached to it drives the internal wheel attached to one of 
the winding-drums. 
To the outside of each winding-dmm there is applied alternately (namely, 
during the time of the running-out of the slack-rope) a break, such break 
being moved by a long sliding bar, carrying the strap-fork, for shifting the 
strap from one pulley to the other. 
The object of this arrangement is, that when the strap is on one pulley, the 
break is applied to the winding-drum (the then paying-out drum) on 
the other end of the shaft, and vice versa. In addition to this arrangement 
there is a small cylinder, provided with a piston, acting by pressure of the 
water from the boiler, connected with two other breaks, which are apjilied to 
the two side pulleys when the change of motion takes place, and it becomes 
necessary to stop them. The same lever which moves the bar to move the 
strap, also opens a valve to allow the water to act in this small cylinder. 
There is furtlier arranged a stop to hold the sliding-bar in position, the bar 
itself being always ready to move by a charged spring. Such stop can be 
withdrawn at pleasure by a long string laid across the field to one of the 
anchor-men ; and this is especially useful in case of accident — if the anchor be 
out of sight of the windlass, from being round a corner, in the hollow of a 
field, or in foggy weather. This arrangement has some advantages : the 
engine can be driven at an uniform speed throughout ; consequently the en- 
gineer reverses the windlass, and, to some extent, looks after the coiling of the
