the size of the claws is inches by 2 inches. This is actuated hy a movable 
imllcy, by which double the jiower exerted by the engine is obtained. We- 
awarded the prize of 10/. to this implement (Xo. 0514). 
Class XV. Beat Combination of any of the uhove Implements not qualified 
to compete in Classes I., II., or III. — The oiler of this prize only brought out 
one competitor, this being Mr. J. A. Williams, of Baydon, Wiltshire ; his com- 
bination being a roller, cultivator, and set of three harrows, price 70?. The 
cultivator is suspended on the roller-.shaft and by means of a lever is raised out 
of the ground when the implement commences to turn. The roller, about; 
2 tons weight, takes 8 feet of ground, and is followed by a cultivator ; and the 
liarrows, which take about 2 feet more in width, work on a bar carried on. 
three wheels, which is to assist an attendant following in lifting. The harrow- 
bar is attached to the cultivator by chain (of too great a length); the roller 
has breaks for an attendant to use when travelling. During one journey of 
this implement it worked ell'ectively ; but the turning arrangements not having 
been matured in detail, some difficulty was found at the land's-end, and finally 
the arm to which the rope was attached became broken and put an end to the 
experiment. The jsrize not awarded. 
Class XVI. Best Implement or part of Taclde, mitaUe for Steam-cultiva- 
tion, of any other description, not 'jualified to conijxte in the prccediny Classes. 
— In this Class we had eight exhibits, namely, six by Messrs. Fowler, consi.sting 
of one harrow-frame, two water-carts, two sleeping-vans, and one ditching- 
plough (an extraordinary implement), and two exhibits by Messrs. Howard, 
viz., their plough-frame, fitted with ridging bodies, and their small cultivator- 
frame fitted as a ridger and snbsoiler. Messrs. Fowler's harrow-frame, fitted 
with two ridging bodies, worked very steadily and well, and would have made 
excellent work if fitted with proper shaped niouldboards ; and Messrs. Howard's 
combined ridger and subsoilcr showed itself in work to be a most useful imple- 
ment for steam-cultivation. Between these two implements we divided the 
jirize of 20?,^ and we recommended Messrs. Fowler's ditching-plough as deserving 
a medal,

Remarks relating to the Table of Experiments (Table III.) on 
Plougldng Machinery. 
The observations made and facts collected are in some instances not as 
complete as could be wished. 'J'his arises partly from the ground actually 
worked by each implement not having been measured at once by the sur- 
vevor; partly from the imperfect manner in wdiich some of the exhibitors 
complied with the very clear printed insti-uctions issued by the Society with 
reference to the measurement of water and the preparations for the reception 
of the indicators ; and partly from the extremely inclement weather and the 
badness of the water at Staflbrd. 
In column 9 the power expended in working the land has been represented 
by the work which would be necessary to raise the earth disturbed the tabular 
number of feet, or by the foot-lbs. of indicated work per lb. of earth moved. 
A singular and unexpected fact appears deducible, namely, that the absolute 
work in foot-lbs. necessary to cultivate the land does not depend materiall}' 
upon the speed at which it is worked; that is, that the coal and water 
consumed per acre, will be the same if the implement travels fast or
