i'orce was not concentrated at any cue part. When nets were first tried, the 
side-ropes were very apt to slip off the driving-wheels; this has lately heen 
prevented by using cross-bars, placed at about the same distance as the rake- 
heads on other machines; the net forms itself into wide piockets between 
these bars, and thus holds the hay more tirmly than in the plain net. The 
price of this machine, without horse-gear, is 45?. 
There now remain to be described the four elevators with 
horse gear fixed below the trough. Of these I will take, first, 
No. 4.391. Holmes and Son. This machine is a very great improvement 
on the one constructed on a similar principle that was tried last year at Cardiff, 
and described on page 456 of the ' Journal ' for 1872. The principal improve- 
ments are the substitution of a wrought-iron central pin, 3f inch diameter, 
for the cast-iron pin then used ; the upper frame has been shortened at the 
feeding end, so that it is now fairly balanced upon the central pin, instead of 
being tail heavy, as it was before. The apparatus for raising the trough has 
also been simplified, and is now similar to that described in Messrs. Tasker 
and Sons' machine.

In [its present form there are three distinct frames below the trough. 
First, a strong carriage-frame, on to which the frame of the horse-gear" is 
bolted when used in stacking hay and corn. The horse-wheel drives a spur- 
wheel on a vertical shaft, which again drives a pair '^f mitre-wheels, and a 
horizontal shaft from the second mitre-wheel drives the pitch-wheel and chain, 
shown in Fig. 9, outside the third and upper frame, which carries the
