The results of these tests have been, on the whole, very interesting. In almost every case, benzol has given better results than petrol, while the benzol-alcohol mixture has given results in some cases rather better than petrol, and in other cases not quite so good. On the average, the mixture has shown itself approximately equal to petrol, so far as consumption is concerned. By visiting Versailles in the early hours of September mornings when the temperature was fairly low, the writer satisfied himself that the use either of benzol or of the mixture did not constitute any serious difficulty in the way of starting up the engines. Moreover, the general absence of offensive smell or smoke seemed to indicate satisfactory combustion of the fuels. As to the results of the French subvention scheme, the fact that the regulations have recently been made more severe, and certain restrictions as to horse-power, weight, etc., introduced, seems to indicate that the number of vehicles available at the time of the outbreak of war must have been at least approaching the number estimated as required. The last series of trials were only just over when war broke out. In these trials some sixty vehicles competed, representative of a considerable variety of makes and types, including a small number of Colonial lorries of special design, and one or two tractors. On the whole, the vehicles went through the trials well, and the opinions of experts who were present were all to the effect that great improvement was noticeable in mechanical details as compared with previous years. Incidentally, it may be mentioned that the big fleet of the Paris General Omnibus Co. forms a very useful and conveniently concentrated supply of substantial cars available either for the rapid carriage of troops, or--by the substitution or conversion of bodies--for the transport columns. Numerically, however, the Paris omnibus fleet falls very far short of that of London, while from the mechanical point of view the vehicles are of heavier construction, and one would imagine less easily handled on narrow and winding country roads.
