And sure enough they did. This great big dirigible, the first of its size to cross the Atlantic Ocean, was landing right before their eyes.

"Let us run over and get as near it as we can," Billy said.

When the monster airship landed, the Chums were not fifty feet away, and stood taking in everything as it slowly settled to earth.

Presently little windows and doors were seen to open in its sides and people came walking out. The Chums went nearer and found out by the conversation they overheard that they were forced to land as something was the matter with the machinery. The longer Billy looked, the more he wanted to see what the dirigible was like on the inside, until at last his curiosity got the better of him and he walked boldly up to the balloon and poked his head in one of the doors and gazed in. Not being driven away, or seeing any one, he stepped in and soon was exploring the balloon from one end to the other, with both Stubby and Button at his heels.

"Isn't it wonderful?" said Billy. "Just as cozy and nice as a ship that sails the sea. Staterooms, lounge, dining saloon, kitchen and storerooms galore! Let's hide and be carried off with her when she starts. It is worth being delayed on our journey to have such an experience."

"Indeed it is!" replied Button.
