So comprehensive a contention was bound to come as something in the nature of a shock to those who were accustomed to regard the Royal Navy of England as "its greatest defence and ornament; its ancient and natural strength; the floating bulwark of our island," and certainly the attribute "entirely" must be considered as being of rather too sweeping a nature, for, serious though the submarine menace became during the world-war, the under-sea boat cannot claim to have swept the face of the waters of anything approaching the total number of ships that swam on the top. There is no doubt, however, but that, not only from the German point of view, but from our own as well, the submarine became an adjunct of the very first importance, and herein, again, was the all-round practical ability of Crewe Works called upon to assist. Bearings for submarine propeller-shafts (commonly known as reaper-bearings) were urgently required, each shaft working in no fewer than sixteen bearings, of which the caps were to be made not only interchangeable, but reversible as well, so exacting were the demands in the Admiralty specification. Indisputably Crewe was "doing her bit," and by their "dauntless spirit," by their "incessant toil," did the mass of employés engaged within the Works enable Mr. Cooke to convince the world at large that England, no longer "la Perfide Albion," was worthy rather to be named "la Loyale Angleterre." CHAPTER IV THE GRAZE-FUSE "A world of startling possibilities." DOLE. Graze-fuses (so called from the fact that the very slightest touch or shock imparted to the fuse or foremost part of the shell by any intervening object, and against which the fuse grazes whilst in flight, is sufficient to cause the spark necessary for igniting the explosive charge) were first taken in hand at Crewe in March, 1915.
