Work on the airship was hastened to such good advantage the next two days that it was in shape for a trial flight, and, one afternoon, the RED CLOUD was wheeled from the shed out into big field, the gas was generated, and the motor started.

There was a little hitch, due to the fact that some of the machine adjustments were wrong, but Tom soon had that remedied and then, with the big propellers whirling around, the airship was sent scudding across the field.

Another moment and it rose like a great eagle, and sailed through the air, while a small crowd that had daily gathered in the hope of seeing a flight, sent up a cheer.

"Does it work all right?" asked Ned anxiously, as he stood in the pilothouse beside his chum.

"As good as it did in Shopton," answered the young inventor, proudly.

"Bless my pocketbook! but that's lucky," exclaimed Mr. Damon. "Then we can soon start, eh?"

"As soon as we are stocked up," replied the lad.

Tom put the airship through a number of "stunts" to test her stability and the rudder control, much to the delight of the gathering throng. Everything was found to work well, and after ascending to a considerable height, to the no small alarm of the old miner, Tom made a quick descent, with the motor shut off. The RED CLOUD conducted herself perfectly, and there was nothing else to be desired.

She was sent down to earth and wheeled back into the shed, and not without some difficulty, for the crowd, which was now very large, wanted to get near enough to touch the wonderful craft.

"To-morrow I'll arrange about the supplies and provisions, and we'll stock her up," said Tom to his companions. "Now you folks had better go back to the hotel."
