Our four young people picnicked cheerfully, and were happy in the manner of a happiness that was an ancient mode in Nineveh. Eyes were bright, Grubb was funny and almost witty, and Bert achieved epigrams; the hedges were full of honeysuckle and dog-roses; in the woods the distant toot-toot-toot of the traffic on the dust-hazy high road might have been no more than the horns of elf-land. They laughed and gossiped and picked flowers and made love and talked, and the girls smoked cigarettes. Also they scuffled playfully. Among other things they talked aeronautics, and how they would come for a picnic together in Bert's flying-machine before ten years were out. The world seemed full of amusing possibilities that afternoon. They wondered what their great-grandparents would have thought of aeronautics. In the evening, about seven, the party turned homeward, expecting no disaster, and it was only on the crest of the downs between Wrotham and Kingsdown that disaster came. They had come up the hill in the twilight; Bert was anxious to get as far as possible before he lit--or attempted to light, for the issue was a doubtful one--his lamps, and they had scorched past a number of cyclists, and by a four-wheeled motor-car of the old style lamed by a deflated tyre. Some dust had penetrated Bert's horn, and the result was a curious, amusing, wheezing sound had got into his “honk, honk.” For the sake of merriment and glory he was making this sound as much as possible, and Edna was in fits of laughter in the trailer. They made a sort of rushing cheerfulness along the road that affected their fellow travellers variously, according to their temperaments. She did notice a good lot of bluish, evil-smelling smoke coming from about the bearings between his feet, but she thought this was one of the natural concomitants of motor-traction, and troubled no more about it, until abruptly it burst into a little yellow-tipped flame. “Bert!” she screamed. But Bert had put on the brakes with such suddenness that she found herself involved with his leg as he dismounted. She got to the side of the road and hastily readjusted her hat, which had suffered. “Gaw!” said Bert. He stood for some fatal seconds watching the petrol drip and catch, and the flame, which was now beginning to smell of enamel as well as oil, spread and grew. His chief idea was the sorrowful one that he had not sold the machine second-hand a year ago, and that he ought to have done so--a good idea in its way, but not immediately helpful. He turned upon Edna sharply. “Get a lot of wet sand,” he said. Then he wheeled the machine a little towards the side of the roadway, and laid it down and looked about for a supply of wet sand. The flames received this as a helpful attention, and made the most of it. They seemed to brighten and the twilight to deepen about them. The road was a flinty road in the chalk country, and ill-provided with sand.
