Markets and Fairs (Weighing of Cattle) Acts have further 
stimulated makers to provide cattle weighbridges suitable for 
auction marts and cattle markets generally. There was a large 
exhibit at Warwick of machines suitable for both purposes. 
The following points should not be lost sight of, in any 
weighing machine intended for use where cattle are bought or 
sold by auction, or where live weight quotations are taken: — 
1. The pen on the platform should be strong, hut not heavier than is 
necessary, and should be so constructed that the animals cannot get their 
heads or legs through it. The bearings should be easily removable and 
renewable. 
‘J, As much as possible the whole operation of weighing shouhi be open 
to view by everyone around the sale ring. 
3. The weighing lever, or steelyard, should be so placed and arranged 
that it may easily be seen that the machine is carefully adjusted before each 
lot of animals are put upon it, as from droppings, and various causes, this is 
most necessary. 
4. It should also be open and easy for everyone to see that a perfect 
balance is obtained by the movement of the poise, or slide, and that the 
weight is correctly taken by the attendant. 
6. The steelyard should be sufficiently long, and so arranged as to admit 
of the figures being large and clear, and the divisions as distinct as possible. 
6. Anyone who wishes should be supplied with a ticket (printed by the 
sliding poise or otherwise), recording the weight which is seen to be indicated 
upon the steelyard by the poise, when the machine is balanced, as the cattle 
stand upon the platform. 
7. The weight should also be shown in some prominent position in largo 
figures (automatically or otherwise) apart from any other figures, and these 
should remain in view until the cattle are sold. 
VII. Steam Digger. 
Article 5382. A[r. Franlc Proctor, of Kneb worth, Herts, ex- 
hibited his Steam Digger, which it was arranged that the Judges 
should see at work on a field provided by the Society for exhibi- 
tions of steam-digging. The Digger in question was built in 
February 1887, and since that time has been used for the execu- 
tion of contracts for digging up land, &c. The engines are of the 
compound type. The nominal horse-power is eight. It is an 
ordinary traction engine, with three digging forks at the rear, 
and is, I understand, the same implement which was exhibited 
at Nottingham, and which is described and illustrated by Mr. 
Pidgeon in his report on the Nottingham Meeting in the Journal, 
1889.' The only alteration since that time consists in providing 
a throwing-out clutch to enable’the driver to throw the digging 
forks in or out of motion, when required, without leaving the 
stoking platform. The Digger easily steamed into the field, up
