"or whether it just went this far on account of its momentum."

"What's that noise?" asked Japheth.

"Sounds like the engine of an automobile," answered Shem.

"It's coming from the Ark," cried Ham.

Capt. Noah hurriedly went below.

Presently he returned, smiling with satisfaction.

"There's a regular automobile engine in the hold, way aft," he said. "And
it's connected with a shaft, so that it will turn the wheels. We'll have
no difficulty in traveling on land."

"Hurrah for the Arkmobile!" shouted Ham.

"On land or on sea,
Wherever we be,
The Arkmobile
Is the thing for me,"

sang Marjorie, skipping about on the sand.

"Over sand, over foam,
Wherever we roam,
The Arkmobile
Will carry us home,"

sang the Weathercock, and then he said: "I guess I'll come down from the
flagpole if you're going to camp here. If you're not, I'll stay where I
am, for it's a pretty good climb, and I'm not much of a sailor as yet."

"Let's stay here and have the circus," said Ham. "We can make a splendid
ring in the sand--in fact, we can have three rings if we want to. All we
have to do, you know, is to throw up the sand in a circle."

Every one agreed that it was an ideal spot, so the boys set to work at
once.

Mrs. Noah made Marjorie a wonderful dress, covered with gold spangles.

"I'm going to ride the big white horse just like a circus rider," cried
Marjorie. "And I shall stand up on the saddle and jump through my hoop.
Ham can hold it."

"Of course I will," he cried, looking up from his work. "And I'll be jolly
glad when this ring is finished. I had no idea it would take so long."

"Hurrah! Mine's finished," cried Japheth.

"And so's mine," shouted Shem.

"Well, I think mine's the biggest of all," said Ham. "It must be, or I'd
have finished when you fellows did."

"Father ought to put on his dress suit," said Shem, "and snap the whip
when Marjorie rides around the ring. You know just the way they do in the
real circus."

"Great Scott!" exclaimed Capt. Noah, overhearing the remark as he
descended the gang-plank. "I didn't bargain for this. But I suppose I
might as well put it on," and he turned back into the Ark.

The sound of hammering at that moment reached them. "What's going on?"
asked Ham.

"Let's see," suggested Shem, but before they reached the gang-plank Mr.
Jonah appeared. On his legs were strapped a pair of stilts, which made him
at least eight feet high.

"I'm g
