"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."
