Fig. 2 represents a bar IJ^ in. in di-ameter, nicked 1/16 in. deep one-half wayaround and bent flat on itself to producerupture and show the fibrous structureof the iron and the stretch at the hollow portion. It also shows the standard V-thread 12 per in. when bent flat on each thread is the equivalent tothe nick which ruptured the other end,no rupture is readily apparent, there very minute ruptures at the base ofevery thread, thus demonstrating the com-plete uniformity of the fibrous structure. Falls Hollow Staybolt Iron is madefrom double refined charcoal billets, andthe long experience of the works in mak-ing this grade of iron as a specialty en-ables them to produce it in a very uni-form quality, so that test samples reallyrepresent the whole amount in any ship-ment. .\s is well known, the Falls HollowStayb
