Steel cannon.
--The London Engineer states that two new guns have just been completed for the
British Government by the
Mersey Steel Company.
They are made of puddled steel, consolidated under the huge steam hammer.
Their length is 9½ feet, weight 4 tons, 3 cwt. Their bore is only 9½ inches, and yet they are intended for 100 lb. shot, of the comical cylindrical form Puddled steel appears to be the most suitable material for making strong cannon.
It is capable of being run almost like cast-iron; then it may be hammered to consolidate its particles, thus imparting to it the duplicate quality of cast and wrought steel, so as to resist both tensile and crushing force in a superior manner.
