Old 2887 is a bully 'bus. I was off the ground and heading up in forty yards. It was rather an occasion for a beginner who had never before flown over twenty-five hundred feet. The little Caudrons, of course, are not high-powered, but she climbed splendidly. In ten minutes I was circling over the camp at thirty-eight hundred feet, and in twenty, I had reached six thousand, just under the roof of the clouds. There was only one blue hole through, so up this funnel I climbed in decreasing circles, till I finally burst out into the gorgeous upper sunlight. At eight thousand feet I began to float about in a world of utter celestial loneliness--dazzlingly pure sun, air like the water of a coral atoll, and beneath me a billowy sea of clouds, stretching away to infinity. Here and there, from the cloudy prairies, great fantastic mountain ranges reared themselves; foothills and long divides, vast snowy peaks, impalpable sisters of Orizaba or Chimborazo, and deep gorges, ever narrowing, widening, or deepening, across whose shadowy depths drove ribbons of thin gray mist. Once, as I was sailing over a broad cañon, I saw, far off in the south, a dark moving dot, and knew with a sudden thrill that another man like myself, astride his gaunt buzzing bird, was exploring and marveling at this upper dream-world. At last the hour was up. I shut off the motor and drove downward in a series of long easy glides. Going through the clouds, one loses all sense of balance and direction. It is bizarre and sometimes dangerous. You plunge out into the old gray world beneath, to find yourself in a nose-dive, or off on a wing, or upside down--it is all the same in a cloud. The balance of the military trials consists in spirals, and so forth, and a lot of cross-country flying by map and compass. First you make two round trips to a place fifty miles away, and then two triangular trips of about one hundred and fifty miles each. It is very easy, if you keep your wits about you and have no hard luck. Roads, railroads, rivers, woods, and canals are the principal guides to follow; towns and cities you can only recognize by having counted their predecessors, unless there is some very prominent building, cathedral or factory. A road, from three thousand feet, shows as a very straight white line, occasionally making angular turns. A railroad is a dark gray line, always curving gently when it turns. Canals are ribbons of water, very straight, between twin lines of trees. And so on. You watch your compass, to check up the tend of roads and railroads, watch your altimeter and tachometer (which tells the speed of your engine), and above all watch always ahead for suitable landing fields, in case of motor trouble. The wind also must be borne in mind; its direction can be told from smoke. I was lucky and had no trouble at all.
