enfilading or direct. State what natures of ordnance were used against them, the 
ranges, projectiles, and general results of the practice. 
44. Describe the cupola for melting iron,—the mode of working it,—the fuel 
we used,—‘the construction of Martin’s shells, and the manner of firing them. 
45. What permament fittings should be adopted in casemates to enable you to 
mount or shift quickly ? Shew by sketch, the arrangements made for shifting the

46. In the absence of any of the fittings referred to in Question 45, by what 
other means could a heavy,—say 12-ton,—gun be mounted on a casemate platform? 
47. Mention when the sling wagon, sling cart, platform wagon and drug, are

human power, what method would you adopt, and why ?
