The receiver slammed up on the hook. Garry grinned at Rooster. "Cal Yates is on his way. A speed boy, or I miss my guess," he hazarded. "He can't be too speedy, either for his father's sake or ours," returned Rooster. Cal Yates justified Garry's opinion of his speediness by appearing at the scene of the accident in an incredibly short time after receiving the telephone message. He arrived in a low-slung racing car, painted a light blue and adorned with a gold stripe. The seat and steering wheel were so low that the driver had fairly to lie on his back as he guided the car along. Despite the gaudiness of the car and the boy's own air of sophistication, Cal seemed to be a likable young fellow and the boys took to him at once. He brought his car to a sudden standstill as the boys hailed him from the side of the road. He wriggled clear of the imprisoning steering wheel and approached them eagerly. "I say, dad isn't badly hurt, is he?" he asked with great anxiety. "You weren't trying just to let me down easy?" "Not a bit of it," Garry assured him. "Come along and see for yourself." Cal Yates followed, and they led him to the spot where his father lay. The latter was much stronger now and greeted his son jovially. "Ahoy there, shipmate!" he called. "The old ship ran afoul of a rock, but the captain's far from being a dead one yet. Don't look so stirred up, son," as he saw tears mist the lad's eyes. "Except for something the matter with my left leg, I'm as good as ever." "Say, Pater, but you gave me a scare!" The young fellow knelt beside his father, feeling him over to see that no bones were broken. "What ever made you do a nose dive, anyway? Didn't know you went in for such things. "Dad was an ace in the World War, you know," Cal went on, turning to the boys, "and what he did to the enemy was a sin and a shame! Shot down about thirty planes--didn't you, Pater?--to say nothing of those that fell in the enemy's lines. As a matter of fact," he added with a quizzical smile, "dad won the war, though he's so modest he doesn't want to tell people about it." Mr. Yates laughed, inadvertently moved his leg and groaned. Instantly his son was all penitent concern. "Here I go, blabbing my fool head off when I ought to have you in the car by this time. Where do we go from here, Dad? To the doctor's? There's a good one near where I'm staying." "There's a fine hospital in Lenox, if you want to take him there," suggested Garry. "Thanks. But I guess I'd better go right to the house where Cal's staying," replied the aviator. "They're relatives of mine, and I can have the doctor see me there. I imagine it wouldn't do any harm for you boys to have the doctor look you over, too." "Oh, we're all right," Bill Sherwood hastened to assure him. "A good night's rest, and we'll be as fine as silk to-morrow morning," added Nick. Up to this time Cal Yates had appeared to have eyes only for his father. Now he regarded the boys with interest.
