corresponding to that of Fig. 3, to represent the means of 
operating the cradle, and illustrating the position of the parts 
when the cradle is in its most distended position, giving the 
largest mesh between its wires and the wires of the screen. 
Fig. 6 represents a transverse section of the screen and cradle 
when in the position of Fig. 5. Fig. 7 is a transverse section of 
the wires of the screen and of the cradle when at their least 
distance apart, when the parts are in the respective positions 
illustrated in Figs. 2, 3, and 4. Fig. 8 represents a view, cor- 
responding to that of Fig. 7, when the said wires are at their 
greatest distance apart, and in the respective positions illustrated 
in Figs. 5 and 6. Fig. 9 represents detail sectional views illus-

cradle upon their several supporting bars or rods. 
The Aylesbury Dairy Co., Limited, No. 903, Patent Ensilage 
Stack Press. — A Silver Medal was awarded to this Company 
for an improvement on Mr. C. Johnson's Patent Ensilage Stack 
Press. Mr. Johnson obtained the prize of 25/. given by the 
Royal? Agricultural Society for the best stack or other system 
of obtaining silage without a silo in England and Wales, in 
actual work during the winter of 1885-6. In vol. xxi., part 2, 
of the Society's Journal (page 729), a description of Mr. John- 
son's press is given ; but since then a great improvement has 
been made in the mode of applying the pressure, the use of 
screws being entirely abandoned, on account of their action 
being slow and the friction great, and a ratchet and lever being 
substituted. For this improvement (Fig. 10) the Judges have 
awarded the Silver Medal of the Society. As at present supplied, 
the gear consists of a series of cross-heads moving loosely up 
and down on ratchet bars made fast to logs of wood placed 
transversely beneath the stack. To these cross-heads is attached 
a flexible galvanised steel rope, laced backwards and forwards, at 
regular intervals over the top of the stack throughout its entire 
length, and which really forms a kind of rope saddle. The 
following illustration (Fig. 10) shows the ingenious arrange- 
ment of ratchet and pawl, by means of which the cross-heads 
are drawn down, tightening the rope, the length of leverage 
being so adjusted that every stroke of the lever moves the cross- 
head down three-quarters of an inch, and a man pressing with 
the weight of 8 stone puts 3 tons on each cross-head, so 
that a stack 16 feet wide has a pressure of 200 lbs. per 
square foot. The lever and pawl are fulcrumed in position on 
the socket provided to receive the former, and from which it 
can be lifted and carried from one cross-head to another, so that 
one lever and pawl are sufficient for any number of cross-heads
