Less than two hundred yards separated the two when Professor Morgan veered to the right, curving so far that his course shifted to a right angle of the other machine, toward which he turned broadside.
There sat the strange man in plain view, his feet on the cross-piece below, his hands resting on the upright levers, between which he sat bolt upright, with his linen duster buttoned from chin to ankles, his cap drawn low, while those blazing black eyes above his grizzled beard suggested an owl peering through a thicket and were turned full upon the two youths in the biplane.
Harvey waved his hand in salutation, but the Professor did not seem to see him or Bunk. He glided past, and when he had shot beyond a point opposite, turned his head so as to look directly in front. Harvey gave him no further notice, for he was now so near the ridge that all his skill was needed to direct his aeroplane.
Bohunkus was not yet free from his shivering fear, and kept his eye upon the dreaded Professor.
“I know what de willain am up to,” he reflected; “he’s only makin’ b’lieve dat he’s gwine to lebe us. He’ll snoke round behind and de fust thing we know will be when dat rudder out in front jams into us, slides under me, lifts me out ob dis seat and pitches me head fust down among dem treetops.”
But the form of the Dragon of the Skies grew smaller and fainter until the aching eyes of the negro could see it no longer. By that time the watcher concluded that nothing for the present was to be feared from the eccentric individual.
“But we hain’t done wid him yit,” said Bunk; “he’s got his eye on us, for if he hadn’t why am he hangin’ round de country, bobbin’ up when we ain’t lookin’ fur him? He’ll find out where we’re gwine to stay to-night and den he’ll get a new axe as big as de side ob a house and smash dis machine wuss dan de oder. De Perfesser am mighty sly and I doan’ like him; I wish he’d take a shine to some oder part ob de world.”
Having surmounted the ridge, Harvey sailed ten or more miles to the northward and descended at a town containing probably ten thousand population. There he renewed his supply of gasoline and oil, and halted for an hour or so, when he was prepared to return to Chesterton. While he and Bohunkus were seated apart from the others at the hotel, the colored youth gave voice to his dissatisfaction.
“What’s de use ob hangin’ round dis part ob de country, Harv? How many times do yo’ expect to go to Chesterton?”
“I have some business there to attend to. When that is finished, we can travel as far as you wish in any direction.”
