direction along the rack. Assuming the plough to be on the 
balance (that is, with the axle corresponding to the centre line 
of the plough), any strain on the hauling rope makes the 
pinions of the axle travel towards the forward end of the 
plough ; and the cam path being parallel with the working end 
of the plough, the front portion of the plough is lifted up and 
the balance overcome. Pulling in the opposite direction just 
reverses the operation. The arrangement is simple, and com- 
mends itself as a decided improvement. 
Messrs. Hayes and Sons, No. 435, Dog Cart. — We could not 
help being tempted into an inspection of the Stand of Haves 
and Sons, Coach Builders, and our attention was centred upon 
their " Rutland Dog Cart," with its perfect balancing and 
brake arrangements. The usual custom and acknowledged 
annoyance, of having the seats fixed with pins in holes, is in 
this cart overcome by an arrangement whereby the hind and 
front seats are secured together, and which can be slided 
backward or forward as maybe required, either to accommodate 
the number of passengers or the gradients of the road ; the 
driver can release a spring attached to the driving seat, which 
at once allows the seats to be slided backwards or forwards. 
Mr. C. G. Roberts, Haslemere, Surrey, Articles 2088 and 
2089. — These Separators, the first (2088) is a simple Separator 
for rain-water for roofs of from 1200 to 1800 ft. area, arranged 
to act slowly in moderate rain and quicker showers, the time 
being regulated by adjustable gauges to give a wash of from 
1 to 2 galls, per lOO ft. super of roof. 
The other (2089) is a compound horizontal Separator for rain- 
water, specially designed where economy of water is necessary, 
and arranged with syphon action, so as to remain canted for 
five hours after the rain ceases, is an improvement upon the 
separators which have from time to time been exhibited by 
Mr. Roberts, and which were illustrated in the Report upon the 
Miscellaneous Implements at Reading (vol. sviii. Pt. 2), 1882, 
and the following year were subjected to a series of trials by 
jNIr. Copperthwaite, Engineer to the Xorth-Eastern Railway at 
York, and also by Mr. Coleman at Escrick, reported in the 
Society's 'Journal' for that year (vol. xix. Pt. 2). 
The results of these experiments showed that there was a 
considerable waste of water in the working of the apparatus. 
To overcome this, in the present machines, great ingenuity has 
been displayed, and so far as can be judged from a cursory 
examination, apparently with success. Without a prolonged 
trial — which it would be desirable to institute — a definite 
opinion cannot be formed. 
A most interesting feature in connection with the meeting of
