The dittlcidty inthe use of steel for large, homogeneous guns is thegreat size of the hammers required to work theblocks into which it is cast. See —A peraun who adheres to his Sover-. A comparison of this gun with rival guns detractsnothing from the Lowell. While the Gatling gimhas ten locks and ten barrels, all revolving at eachshot, the Lowell Battery gun has but one lock anduses but one barrel at a time. The disabling of onelock or barrel of the Gatling renders it useless untilrepaired by a skillful mechanic. A disarrangementof the Lowell can be remedied by the renewal of alock or change of the barrel, which can be done inlive seconds by any person of ordinary Mitchinr dun and Buttery Guns.
