470 Miscellaneous Implements Exhibited at Cambridge. 
gang ploughs, this eight-furrow turnover steam plough has a 
bar carried by wheels on each end, to which are attached by 
proper draught-links four pairs of ploughs ; each pair being 
entirely separate from the others, and free to rise or fall with 
the varying surfaces of the land. Its superiority in exactitude 
of work over the rigid beam ploughs scarcely requires statement. 
The rigid beams worked irregularly over unequal surfaces be- 
cause the ploughs, being fixed in an immovable line, were unable 
to make that equal attack upon the varying elevations which is 
within the power of the new plough. But this new plough has 
other points of superiority over the older ploughs. Each of 
its eight ploughs has two mould-boards : one rests in the air 
while the other is ploughing ; but, when the end of the field is 
reached, the mould-board in the air, by an ingenious automatic 
arrangement, falls to the ground to do its share of the work, 
while the other takes its resting-place for the return furrow. 
The carrying wheels and frame do not affect the depth of the 
furrows. This is regulated independently, the weight of the 
shears and moulding boards ensuring uniformity. Its trial 
took place upon a piece of land where clover had been cut and 
stacked, and where the soil was heavy and wet. It proved itself 
capable of ploughing this at the rate of 30 to 4*0 acres per day. 
The plough is 19 feet long, presents a fine example of ingenuity 
and careful workmanship, and is altogether capable of accom- 
plishing the end for which it was designed. 
Other Exhibits. 
There were several machines of a praiseworthy character, 
and amongst them the following deserve mention : — 
Article 542. Mr. T. A. Wynne Edwards, Denbigh. Hay 
and Straw Box Baling Press. Price 30k — This press (figs. 2 and 
3) is horizontal. When the ram is back the open space measures 
5 feet by 4 feet — a larger opening than in the vertical presses, 
easier to fill by throwing from the stack, and giving more room 
for a man to turn about and pack the hay. When filled, the lid 
is closed and fastened by automatic levers. Four strong racks and 
pinions, moved by a ratchet lever 7 feet 6 inches long, which is 
worked by two men, and the shaft of which is geared with the 
two main shafts of the press, then force in the ram. The lid is 
opened, the bale tied, and a false end falls back, permitting its 
easy extraction. With this press two men can truss and tie about 
34 tons of hay or straw per day. 
Article 737. Mr. John D. McJannet, Woodlands, Stirling, N.B. 
Weighbridge for Carts and Cattle. Price 18k — This weighing
