act, in various counties. The plan is specially adapted for 
lly land, enabling a portable steam-engine of small or moderate 
)wer, stationed beside a pond or brook, to communicate 
otion to hauling-windlasses at a great distance or upon steep 
rfaces : the area of deep or heavy work done per day is greater 
an might have been expected from the comparative lightness 
the tackle, and, under good management, the wear of the 
•mp or Manilla rope is not found excessive. 
Direct hauling by steel-wire rope, as brought before the 
)rld about a quarter of a century back by Mr. John Fowler, 
r. David Greig, Mr. William Smith of Woolston, and Messrs. 
oward, is the system distinguishing the many hundreds of sets 
apparatus which perform the great bulk of the steam hus- 
ndry of the kingdom. 
Three distinct modes of application are followed : namely, Wire-rope 
<ein which the engine and windlass are stationary; another ^y^*"*""*" 
which the engine is shifted along one headland opposite to 
. anchor with pulley traversing the other ; and a third in 
lich two self-shifting engines, with winding drums, are em- 
]iyed on the two headlands, hauling the implement to and fro 
it ween them. 
The first plan has several modifications. In some cases the 
<1 method is retained of laying out the rope round all four 
iles of the field by means of a pulley at each corner hung to 
; ;law-anchor ; the anchors at the ends of the furrow or course 
ti. versed by the implement being removed and shifted forward 
:)ng the headland at every bout by labourers employed for 
t' purpose. To save this manual labour, the self-moving 
;chor is adopted, the frame carrying the rope-pulley being 
wanted upon four or more small travelling-wheels fitted with 
sirp discs which cut through the soil and present a sideway 
ristance to the strain of the plough-rope. In the anchor of 
-issrs. Barford and Perkins, of Peterborough, the plough-rope, Jlessrs. 
Id out along the headland, pulls the anchor forward at intervals Harford and

1 en the strain is on ; the movement is arrested at the required machinery. 
]int by rotary tines or claws clutching into the ground in the 
i'.r, and the distance passed over is self-regulated by means 
* a releasing and stopping lever-motion operated upon by a 
I 1 set in any given position upon the rope. In the anchor of 
j!;ssrs. Howard, of Bedford, the rope -pulley gives motion to a 
s.all barrel which very slowly winds along a rope fixed on the 
Udland, and also carries the disc-anchor forward until the action 
istopped by self-acting mechanism set according to the breadth Messrs. John 
• the work which is being done. Messrs. John Fowler and Co., q^TJ^"^ 
Leeds, construct their self-moving disc-anchor so as to wind machinery.
