. The railroad and engineering journal . ould haveoccurred, we hold that any system of design or construc-tion which renders boilers and engines dependent for their FIC.5 In .o. 47 the failure was sudden and complete; and, aswe know, lives were lost. In the case of No. 57 the failureof the crown plate was not .so sudden and complete, andno lives were lost; although the risk incurred was awful.Why did the furnace crowns come down. The first replythat will suggest itself to an engineer is that they camedown because the boilers were short of water. On thispoint, however, there is a great deal to be said ; and inorder that our readers may comprehend the whole matter, we give here two sets of drawings—figs, i, 2 and 3—show-ing the system of construction adopted by f, Messrs.Yarrow & Co.; and figs. 5, 6 and 7, that used by Messrs.Thornycroft & Co. At first sight there does not seem to be much differencebetween them, but there is a difTerence—a most essentialdifference in detail. It will be seen that in neither boiler.

Whatever the probable shortcomings of thecrews in charge could possibly have been, we think themain cause of the failures must be sought and found inthe machinery of the boats, and even in the boats them-selves, and we fancy, before we have done, that our readerswill be of the same opinion. As we know nothing yet ofthe nature of the failures which took place in the engineor boiler rooms of Nos. 27, 41, 50, 42 and 55, we can saylittle about them. No. 27 had hot bearings; but they musthave been very hot indeed to stop the boat. The bearingsin a torpedo-boat engine are so comparatively small andlight, and the appliances for cooling so perfect, that, as isknown from experience, a very hot bearing can be cooledin a very
