Owing to the cxtvcinc liardncss of tlio ground, one sliare was removed from 
cacli cud, and the iniitlemcnt took four furrows or breadths at once, going on 
an average (if'*, inches deep, as calculated from tlie weight moved, and leaving 
a capital surface. 
Notwithstanding the relief atforded by the removal of one share, the work 
severelj' tried the anchors, and occasional delays occurred in consequence. 
This partly accounts for the comparatively sm:'.ll area worked. 
The area dug or cultivated was 1 acre 1 rood 17 perches in 2 hours 49 
minutes, being at the rate of 1 rood 37 perches per hour, or 4 acres 3 roods 
10 perches per day of 10 hours. 
In each experiment several iiortions of the soil were weighed and compared 
with the actual weight of a portion of solid ground, and the depth moved : 
the number of tons j)er acre were thus ascertained. 
The weight of the undisturbed soil in tliis field was as follows : 1 yard 
square, first 6 inches deep, 30 stones 13 lbs. ; second G inches deep, 37 stones 
5 lbs. The deeper we go down within certain limits, the heavier become a 
the soil. 
The weight of a yard square of the depth cultivated by Aveling and Porter 
reached an average of 32 stones 5 lbs., or 978 tons IG cwts. per acre. 
The actual average depth in this case, though apparently more, was only 
G'{)r inches, when truly ascertained by calculation of the weight moved. 
Lot 2. — Messrs. J. and F. Howard's celebrated "Roundabout" system is 
too well known to the public to need a lengthened description. 
The apparatus (No. 1194 in catalogue) includes a 10-horse-power portable 
engine by Clayton, Shuttlcworth, and Co., a separate windlass, IGOO yards of 
rope, anchors, and a double-action 5-tine cultivator : price complete, 5001. 
'J'he windlass, driven by a shaft with universal joints, is very efficient and well 
made, moving the cultivator by a rojic properly carried and very well anchored. 
The cultivating implement itself (to be noticed later on, among the imple- 
ments tried), which is double-acting, works with great steadiness, takes a good 
hold of the ground, and leaves a very level bottom. 
It consists of a strong iron frame on 4 travelling wheels, capable of carrying 
5 strong tines (4 only were in use), with jocks or points in both directions, 
various sized soles being fitted in the centre between the points. The tines 
rock on the frame ; the distance through which they rock can be adjusted. 
This abilitj' to rock is a very important advantage. 
In travelling to the field no less than eight horses were employed. The 
time occupied was 6 minutes in moving, and 58 minutes in preparing for work, 
— a long period as compared with that of direct sj'stems. It must, however, 
be borne in mind that sometimes, with a little arrangement, two or even three 
fields may be cultivated without shifting the engine. 
The work when once started was continuous ; every part appeared well 
balanced ; and the pace was good, as was proved by the fact that 2 acres 34 
perches was moved to an average depth of 5f inches in 2 hours 14 minutes. 
The weight of a superficial yard of soil the depth cultivated was 29 stones 10 lbs. 
In this windlass, as in all the other detached windlasses, there is not any 
mechanical means of coiling the rope on the drums ; whereas the important 
point of uniformity of coiling depends upon the skill of the man in attendance, 
coupled with the judicious placing of the snatch-blocks in front of the windlass. 
Loi 3. — W. Tasker and Sons' apparatus consists of a 12-horse 
power Double Cylinder Traction-Engine, by Clayton, Shuttlcworth, £ 
and Co. (No. 5516), costing 440 
(No. 5517) windlass, ropes, porters, and anchors, by exhibitors ;
