Stewards and officers. To Mr. James Amos ouv best thanks are also due for 
his indefatigable exertions and the services he rendered in ascertaining the 
power required, and recording dynamometrical results, besides the general 
assistance he gave us during the trials.

Worcester, July 21st, 1863. 
Among the recognised, if not the essential, adjuncts of the 
thrashing-machine, whether it be employed in the field or in the 
barn, is the Straw-elevator, of which several new and cheaper 
forms were exhibited at Battersea, but of course without autho- 
rized trial ; the Worcester Show was therefore a fitting occasion 
for the Society to take such cognisance of this machine as cir- 
cumstances warrant. 
Those first in use are attended with this drawback — that, having 
a tall frame mounted on a separate four-wheeled carriage, they 
were not easy of transport or of stowage. Moreover, their cost 
— from 501. to 60/. — was disproportionate to the requirements 
of the case, or even to the materials actually employed. 
The endeavours of Messrs. Wright and Campaign to diminish 
the cost and simplify the apparatus, are deserving of special 
notice and trial. Wright of B(;ston's Stalking-machine, when 
self-contained, as he sends it out, packs up into a verv compact 
form, and, when modified according to Messrs. Ransome's patent, 
is but an appendage to the thrashing-machine when travelling. 
A long net, strained and raised by shears composed either of 
telescopic iron tubes or of wooden poles, which slide out to a 
length of 30 feet, supersedes the cumbrous wooden frame which 
is so cofnmonly seen standing exposed to the summer sun. 
Campaign's Elevator, as exhibited by Messrs. Clayton and 
Shuttle worth, is preferable where the straw has to be delivered 
at a considerable distance and height ; but this very ingenious 
arrangement requires the labour of one man, with probably a 
boy in attendance, to tie up the straw in bundles. 
In the internal fittings of the thrashing-machine the most 
important novelty is the Corn-elevator, invented by J. W. Bruck- 
shaw and exhibited by W. S, Underbill. This apparatus was 
first brought out at Battersea, but it has never until this year 
come under the notice of Judges, whose opinion of its merits 
would have been the more acceptable, since some of our first 
implement-makers have adopted its use. 
Its action may be thus briefly explained : — The Elevator con- 
sists of an ordinary fan-spindle with blades upon it, Avhich is 
driven at considerable speed. The corn from the riddles falls
