Fender, of Buenos Ayres. This inventor follows, at a long dis- 
tance of time, somewhat closely in the footsteps of Mr. Boydell, 
the originator of the fomous " Boydell 8team Horse," but 
he attains the same object by somewhat simpler means. Mr. 
Fender applies a ring of wide wrought-iron shoes, linked loosely 
together by ordinary chain, to the wheels of a traction-engine;

(See page 108.) 
carrying the weight of this arrangement upon a strong wrought- 
iron frame, which keeps the " Railway " out of touch of the peri- 
phery of the driving-wheels. When the engine is at work, the 
chain of shoes forms a pathway, constantly laid down and taken 
up again, for the passage of the driving-wheel, which therefore 
travels along an endless railway. 
Mr. Wm. Brenton, of East Cornwall Works, St. Germans, 
Cornwall, exhibited a new corn and seed drill (Art. 2170) having 
certain features of novelty and apparent merit. 
The seed-deliverer in this implement consists of a roller 
having a concave surface whose smallest diameter is midway 
between its two ends. Here are a number of curved teeth 
adapted to move the gi-ain towards the discharge opening, which 
is itself provided with an adjustable slide for the purpose of 
increasing or decreasing the quantity of seed sown. Once in 
every revolution of the concave seed roller, a brnsh attached to 
its circumference cleans the discharge opening, towards which 
the seed is constantly compelled to fall by the concavity of the 
feeding roller. Mr. Brenton also showed a mowing-machine 
fitted with " lock-jaw" fingers, an arrangement which makes it
