Whether it were an act of wisdom to lock the barn door after the horse had been stolen would depend upon the value ofthe harness; so what is often referred to as a proverbially ridiculousproceeding may, after all, be based on sound judgment, althoughif the barn-door lock is to be a real safeguard it should be purchasedsimultaneously with the horse. At first glance it may be difficult to find any relation between theforegoing observations and the fly wheel explosion, the results ofwhich are shown by the accompanying photographs, but a briefrecital of the history of the accident will not only establish a con-nection, but should impress upon the owner of each engine that hehas a barn door to lock. In the ordinary course of our business transactions an applica-tion for insurance was received on the 12-foot engine wheeloperated as part of a Corliss type engine in a middle-west manufac-turing establishment. An examination of the wheel, valves and I9i8. THE LOCOMOTIVE 14.

Considerable has been written on the subject, but it may notbe amiss to describe fully the conditions which were consideredsufficient to temporarily prevent the insurance of the wheel. The speed at which the wheel of a Corliss type engine rotates isregulated by the amount of steam at boiler pressure admitted ateach stroke, and when sufficient steam has entered the cylinder thevalve closes. Should the load increase, a greater volume of steamis admitted and in case the load decreases the volume is changes in admission are to a slight extent continuous duringthe time the engine is in operation even under a
