Part 3

"Uncle Hen?"

"Yes, Pete," from the dock, where Uncle Henry was star-gazing in the opposite direction.

"Why do they call 'the big dipper' the 'great bear'--and is there any 'little dipper'? Betty says there isn't, 'cause she never saw it."

Uncle Henry stepped off the dock upon the smooth sand, kneeled down, and without answering began collecting little smooth pebbles.

Peter sat up and asked in surprise,

"Don't you know, Uncle Hen?"

Surely this genius, who could make new kinds of kites, and willow-whistles that "worked fine," was not going to fail now. The other children turned to him, expectant too. Betty herself was willing to be proved wrong about the existence of the "little dipper," rather than admit a limit to Uncle Henry's wisdom.

"Let's make a nice, smooth place on the sand," said Uncle Henry, his hands now full of those mysterious pebbles. These he put into his pocket and began, on all fours, to smooth sand industriously.

"Come on, youngsters," he invited, "and I'll let you settle the questions yourselves. We'll make a game of it," he added.

The trio breathed easier. Uncle Henry did know, and was going to tell--in a new, interesting way. Three pairs of hands started smoothing sand, with some waste of energy, but with rapid results.

"Now," said Uncle Henry, squatting down before the leveled place, and pouring out the pebbles in a little pile, "how many stones do you need to make the dipper, Pete? We'll draw it on the sand, with pebbles for stars."

Three necks craned upward in unison, and the two boys' voices answered, almost together,

"Seven."

Betty gazed a moment longer, and said,

"Eight."

Uncle Henry looked interested.

"Where do you see the eighth, Betty?" he asked.

"Right close where the handle bends," announced Betty.

"Correct," said Uncle Henry, "that shows you have good eyes. The Arabs used to call that little star 'the proof,' because it is a test of good eyesight to see it. The star at the bend of the handle is also called 'the horse,' and that faint little star over it 'the rider.' You can make the dipper itself with seven pebbles, though. Go ahead and do it, Peter," Uncle Henry finished, "and take good-sized stones, to show that they're bright stars."

When Peter had finished, the smooth patch of sand looked like this in the light from Uncle Henry's pocket electric torch.

Betty insisted upon adding a tiny stone above "the horse," to represent her discovery, "the rider."

"Now," said Uncle Henry, looking upward, "I'll help you this much in finding all of 'the great bear.' The handle of the dipper is his tail. Everybody try to find the rest of him. Put down a pebble in the right spot for every star; big ones for bright ones, and little stones for faint ones."

"Ooh," interrupted Betty, "I got his nose!"

Here is where Betty put it.

"--and his shoulders!" she added in a moment, putting them in with small pebbles.

"I got his front leg!" announced Paul excitedly, adding three pebbles rapidly.

Then the bear looked like this.

It was Peter who contributed his hind legs and his "skeleton," made of finger-drawn lines in the sand. Like this.
