There are four cylinders, butthe valves are only two in number just as usual in the most ordinarytwo-cylinder engine. Relatively to the number of cylinders, the Ital-ian arrangement is therefore simpler than engines which require onevalve for every cylinder. Here, one valve suffices for two. The en-gine is, effectively, a double two-cylinder compound—the cylinders

Anatole Mallet in 1876, buttwinned—with two high-pressure on one side and two low-pressure onthe other—an arrangement that has given the very best of results inservice, there being no compound engines which run with greaterregularity of movement. At the time of writing, 88 engines are inconstruction with these cylinders, of which 12 are at Maffeis. Themachining of these pieces is interesting by reason of the size of thewhole group when bolted together—close to the center line. Theprocess of working as carried out in the .Ernesto Breda LocomotiveWorks of Milano, Italy, Is shown in the accompanying views. Thecylinders are rough-bored for detecting any defect which would atonce condemn the casting. A double-headed cylinder borer by the
