"Say, Frank," he began hesitatingly, "I don't suppose you could—"

Frank turned and saw the wistful look in the young reporter's eyes.

"Take you up?" he said, with a laugh at Billy's downcast appearance.

Billy nodded.

"Well, there's not much room for passengers the way she is fixed at present," laughed Harry catching Frank's mirth, "but if you want to squeeze in by me here, you can. Here, Le Blanc, bring out that spare seat."

A few seconds later the delighted reporter was sitting on a small aluminum seat fitted with clamps to screw to the framework, and handles to grasp hold of tightly when the craft was in mid-air.

"Let her go," cried Frank, as soon as the delighted Billy had taken his place.

Sanford and Le Blanc, one at each of the propellers, gave them a few twists, and after about the third silent revolution there came the startling roar of the exhaust that told the boys that all the cylinders were getting down to work. Blue flames and smoke belched out of the vents and the mechanics sprang back, as the propellers whirled round at a pace that made them seem blurred shadows.

"Hang on till I get up speed," shouted Frank to the two mechanics, who, with several volunteer helpers, seized hold of the rear framework and held the struggling aeroplane back with all their might. Her frame shook as if it was being swept by some mighty convulsion. The racket was terrific, ear-splitting. The wind from the propellers blew hats in every direction and streamed out the hair of the men holding the aeroplane back, as if they had been poking their faces into an electric fan.

Faster and faster the propellers revolved, as Frank increased the power of his mixture and advanced the spark. At last, when the men holding the craft were shouting that they couldn't hang on much longer, Frank dropped his hand, the signal that the craft was to be released.
