Fig. 11. — Plan iUusiraiing the two modes of ploughing with Messrs. 
J. Folder and Co.'s Double-Drum Engine and Travelling-Anchor Set, 
No. 6484. 
At Bamhurst, on June 27th, this apparatus was moved into the field and 
set down ready for work in 40 minutes, which includes the time lost in adding 
40 yards length to the rope. Six men were engaged. On leaving the field, 
after the trial was completed, the accidental breaking of an axle of the anchor 
occurred. The hands engaged in working were two men and three lads, 
one of these regulating the advance of the anchor. The plot of 2 acres 3 roods 
11 perches was broken up with the 5-tine turning cultivator in 1 hour 
42 minutes, being at the rate of 16 acres 2 roods 13 perches in 10 hours, or 
19 acres 3 roods 30 perches in an autumn day of 12 hours. The average time 
in turning at the ends was 2G seconds. The work was exceedingly good, well 
broken up, and the bottom quite level. The depth, which was 62 inches at 
first, was increased to 9 or 9 2 inches, and averaged 8 inches. 
Plot 7 in Field No. II. The Ravensthorpe Engineering Company's 10- 
Horse Portable Engine" and High-speed Rope Set (Catalogue Nos., 6022 and 
6024), consisting of 10-horse-power portable double-cylinder engine of Clayton 
and Shuttleworth ; the cylinders of 7? inches diameter with 12 inches stroke, 
weight 4 tons 17 cwts. ; two travelling windlasses, six corner anchor- 
pulleys, one tension anchor-pulley, two claw-anchors, thirty light rope-porters,. 
1200 yards of Manilla rop)e, 800 yards of best steel-wire rope, one 4-furrow 
Fowler combined plough and digger, one 9-tine Howard reversible cultivator, 
&c., price 687Z. The question of light swift-running ropes versus strong 
slow-running ropes for driving cranes and other machinery, has occupied of 
late years a great deal of attention and provoked much controversy ; and it is 
interesting to find the same problem reappearing among the various methods- 
of steam-cultivation. The arrangement adopted, in what is called, after the 
inventor, the " Fisken " system, is as follows : — An ordinary jwrtable engine, A 
(in the sketch Fig. 12), or it may be a self-moving engine, for the purpose of
