Nothe of this city exhibited small model of rSl-
road car the sides and top of which were peculiarly
sontruced entirely of iron. One city car constructed
in this manner had been many months in successful
operation. The adv antages were increased lgatness
and safety compared with the wooden cars. Mr..
James A. Clark of this city exhibited very cheap,
fine mode of an Dvs ntiOn very much needed-a coal
weighing cast. Coal delivered from coal yards in
this city, had been carefully weighed, in some cases
within hs knowledge and found to reach only about
200 n. when tun was ordered and psid for His
device seemed TO consist in making the cart body
scale. which by few turns of crank at the for
ward end could be made bear with its whole weight
upon weighing apparatus beneath, and indicate the
load in the usual manner by movable lever at the
side In the brief discussion which followed the ex-
pense of such an apparatus if applied to all the carts
Of a large coal concern, was urged as killer
against the scheme; but the inventor claims that the
expense for each cart would be but about $50 or $780,
and we fancy the concern adopting it might, ii well
managed, easily monopOize the trade. Mr.. William
