FRENCH CANNON.

Five new cannons, the largest yet manufactured in France, have been

successfully cast in the foundry of Ruelle near Angouleme. They are made

of steel, and are breech loading. The weight of each is 97 tons, without

the carriage. The projectile weighs 1,716 pounds, and the charge or

powder is 616 pounds. To remove them a special wagon with sixteen wheels

has had to be constructed, and the bridges upon the road from Ruelle to

Angouleme not being solid enough to bear the weight of so heavy a

load, a special roadway will be constructed for the transport of these

weapons, which are destined for coast defences and ironclads.
