rope all round the field, but in two lines parallel with the 
furrow ; and the windlass is again mounted on the plough, in 
somewhat the same manner as it was at the last Rojal Agri- 
cultural Society's Show at Carlisle in 1855. 
Mr. Frederick Savage, King's Lynn, Norfolk, worked in the 
trial-field a ten-horse-power Agricultural Engine. The driving- 
wheels form the winding drums, as is usual in these engines. 
The anchors are self-moving, and the whole weight rests on the 
retaining tines. A new implement was shown in connection 
with this tackle, viz,, a four-ring self-acting Presser and Drill 
Combined, to be used behind the plough. A swivel foot,

lowered on to the ground by a lever, takes the weight of the 
presser in turning at the headlands. A small harrow is also 
attached, and drawn behind the presser, for covering the seed. 
This is the first implement of the kind ever made, so doubtkss 
many improvements on it will appear in time, and in certain 
hands on some soils will probably prove of considerable value. 
3Ir. J. A. Mays, 223 Grcsham House, London, showed a 
curiously contrived Revolving Railway attached to the driving- 
wheels of a six-horse-power Traction Engine, which consists of a 
series of plates or feet about 15 inches square, connected by 
links and ball-and-socket joints to a ring, which ring fits on 
to the driving-wheel, and the two are only connected by the 
frictional adhesion caused by the weight of the engine. As 
the wheels revolve the feet come down on to the ground and 
are picked up in turn, two being on the ground at once. The 
feet are faced with wood strips. One of the wheels met with
