TWO:At the "Oud Slot van Vlaanderen," a large, ancient castle, there was a lot of hustle and bustle of carriages and motor-cars. We had not gone another two hundred yards, when someone came after us and stopped us as suspects. We were escorted back to the castle, where a general command was established, and an aviators-division, with the motor-section attached to it. Happily our detention did not last long, and after examination we were released. On the road was an infernal noise, as the violent roar of the cannon was mixing with the roar of the wheels of the heavily-loaded convoys and the whirr and hooting of the army motors. Long processions of field-kitchens passed us also, most of them brand-new; but it was remarkable245 that all carts arranged for a team of two were drawn with great difficulty by only one horse, and also that so many civilians have been compelled to act as drivers, or to gather the wounded."Retire to the Continent. Tomorrow you let me have 500 as a guarantee of good faith. Then I leave you--for the present. After that you can marry the young doctor who has won your affections and be happy--for, say a week."
TWO:Lastly, proportions; having estimated the cutting force required at one ton, although less than the actual strain in a machine of this kind, we proceed upon this to fix proportions, [157] beginning with the tool shank, and following back through the adjusting saddle, the cutting bar, connections, crank pins, shafts, and gear wheels to the belt. Starting again at the tool, or point of cutting, following through the supports of the rack, the jaws that clamp it, the saddle for the graduating adjustment, the connections with the main frame, and so on to the crank-shaft bearing a second time, dimensions may be fixed for each piece to withstand the strains without deflection or danger of breaking. Such proportions cannot, I am aware, be brought within the rules of ordinary practice by relying upon calculation alone to fix them, and no such course is suggested; calculation may aid, but cannot determine proportions in such cases; besides, symmetry, which cannot be altogether disregarded, modifies the form and sometimes the dimensions of various parts.CHAPTER V MYSTERY IN THE FOG

TWO:It is better to have two boards, so that one may be used for sketching and drawing details, which, if done on the same sheet with elevations, dirties the paper, and is apt to lower the standard of the finished drawing by what may be called bad association.And fill the plain with armed men, for I
