a quarter after eleven
o'clock
Colonel Howell had explained to them that the Indian village they were seeking was one hundred miles from the gas camp . As it was not certain that Pointe aux Tremble could be easily made out from a distance , it was necessary to keep careful watch of the chronometer and the propeller revolution gauge . The flight over the picturesque banks of the great river was now getting to be an old story to the boys and protected as they were in the inclosed cockpit , the journey proceeded with only occasional comment . They had left the camp at nine twenty-five o'clock , having set the engines at fifty miles , and , allowing for their detour , at a quarter after eleven o'clock Roy arose and began to use his binoculars . But either the reputed distance or the boys ' calculations were wrong , for it was not until a quarter of twelve o'clock that they caught sight of a few cabins scattered along the riverbank within a fringe of poplar trees . It was necessary to find a suitable landing place and both aviators busied themselves in this respect with no great result . What clearing there was seemed to be full of tree stumps and large brush .
