Thanks once again to the courtesy of General Gallieni, who agreed to supply "thirty-four of the famous French 75-millimetre guns and twenty thousand shells with fuses complete," Sir Percy Scott finally had at his disposal a total of one hundred and fifty-two guns, which, although admittedly "rather a mixed lot," combined to frustrate the designs of those "airy devils" which so frequently were wont to-- "hover in the sky and pour down mischief." As time went on, however, and when, notwithstanding the constant alertness of our gunners and the shoals of "archies" spat heavenwards in search of these enemy marauders, the persistency of the latter showed little if any sign of abatement, the idea of retaliation, or the practice of paying the enemy back in his own coin, was mooted as likely to prove the most effective method of clipping his wings, and in spite of protests from that misguided section of the community, aptly designated the "don't-hurt-poor-Germany-brigade," the clamour for retaliation, emanating from an already-too-long-suffering public became so insistent that orders were at length placed for a supply of that special form of "mischief," or medicine, known as aerial bombs, in the manufacture of which, both petrol-incendiary and high-explosive, Crewe Works was requested to assist, and which our gallant airmen were commissioned to "pour down" on fortified positions on the further side of the Hindenburg Line. How efficacious were deemed to be the ingredients of this medicine may be gathered from the fact that in the autumn of 1917 the chief mechanical engineers of the great railway companies assembled in conclave at the request of the Air Board, and expressed their willingness to co-operate in the manufacture of aeroplanes of the bombing order. Owing, however, to the special conditions applying to the aeroplane industry, and to the fact that those responsible for the administration of our Air-policy decided, after mature consideration, that the scope for producing these machines was actually sufficient for dealing with every emergency, this additional strain was not imposed on the already heavily taxed capacity of the various locomotive workshops after all. Crewe, nevertheless, was not to be gainsaid the privilege of undertaking at least some share in the production of our heavier-than-air machines, and in the tinsmiths' and fitting shops respectively were turned out hundreds of tiny metal pressings or discs, and knuckle joints, essential for the piecing together of the wood fuselage, and on the quality of which depended so largely the lives of our pilots, to whose intrepid instinct undoubtedly "one crowded hour of glorious life" seemed at all times "worth an age without a name," but who nevertheless had no particular wish to come to grief owing to faulty material. The airman in common with the traveller-- "Cheerful at morn, wakes from short repose, Breasts the keen air, and carols as he goes;"
