"You will find the road has been badly shelled at the next village," said the brigade-major, holding up his map-case and tracing the route Dennis would have to follow. "And here, at this point, the supply column got it rather badly earlier in the night--there may be wagons still lying about. When you've passed that it's all plain sailing." "Do I report to you, sir, on my return?" inquired the boy. "Yes," said the brigadier. "Then you can leave the bike and rejoin your company. I could have 'phoned this, but it's all experience, and may stand you in good stead." Perhaps the brigade-major, as he nodded a cheery good night, understood the father's wish to place the youngster out of danger, if it were only for a few hours, but as Dennis swung into the saddle and waved his hand, neither he nor the brigadier foresaw the things that were going to happen. The road was a fairly straight one, and Dennis found the shell holes without difficulty, shutting off his engine only just in time as he plunged down into the first of them like Quintus Curtius of old. "Hang it, that's a bad start," he laughed when he found the machine had sustained no injury, but it took him a good five minutes to get it up again, and after that he was more careful. A little farther on he encountered a supply column of the A.S.C., and coasted by them without much difficulty, until at last a red lantern gleaming above a green one told him that he had reached Divisional Headquarters. There he found the staff busy, and a good deal of quiet bustle as the various brigade commanders' reports arrived, and a telegraphic operator in a shell-proof dug-out was transmitting the night's news to Sir Douglas Haig at ----. Dennis handed in his dispatch, which was duly read by the lieutenant-general commanding the division, a florid officer with a white moustache, who held the communication in one hand while he rubbed his chin thoughtfully with the other. "Where is the officer from General Dashwood?" he inquired suddenly, and word was passed for Dennis. The divisional general looked him up and down for a moment, and his brow cleared. "If you are not wanted immediately I should like you to carry a query for me to the officer commanding the brigade on the right of the division," he said. "There is something I do not quite understand in his report, and unfortunately, the field wire has broken down somewhere and we can't get through to him. Is your machine in order?" "Yes, sir," said Dennis, and the general turned to a shorthand clerk. "Just take this down, will you? And type it out quickly," he said, and he rapidly dictated to the man. "Captain Thompson," he said when he had finished, "kindly explain to this officer how he is to reach Donaldson," and the staff captain took the young lieutenant to the large scale map at the end of the room, where everything was marked out in squares, each numbered and lettered.
