twinkling.
âChet,â Frank said, âyou go back. Joe and I will find out what that glittering thing is.â
Nervously the chunky boy considered the expanse of desert between him and the blue airplane. No telling how many Gila monsters he might meet!
âAlone?â he asked blankly.
âSure. Go on. Wait for us at the plane.â
Wistfully, Chet considered the distance again. âNo,â he protested in a forced hearty voice, âyour folks would never forgive me if I let you down.â
The Gila monster disappeared under a bush and the three boys started forward again. Ahead of them the unknown object flashed in the sunlight. After walking for some time, they did not appear to be much closer. All three boys were wearing moccasins, and the heat from the broiling sand made their feet uncomfortably warm.
âSay, do you think that thing is moving away from us?â Chet complained. He took out a gaudy handkerchief and began to mop his face.
âItâs tied to the tail of a Gila monster!â Joe teased, and Frank added, âOut here you can see twenty miles instead of two or three miles as we can at home.â
As the boys finally approached the mysterious glittering object, they saw that it was a twelve-inch, round, metallic rock which caught and reflected the sunâs rays.
Joe rushed forward to investigate. He found the big rock studded with lovely solid-colored stones. Some were dark red, others a rich brown, a few deep green. Nature had placed these stones in the rock like jewels.
âThatâs beautiful, Joe,â said Frank, as he came up. âWhat is it? Some kind of quartz?â
Back in Bayport, Joe Hardy had an extensive collection of rocks and stones. Now he carefully examined their find.
âJasper, Iâd say. Very fine specimens, too.â
As slow-moving Chet joined them, he said, âSay, that stuff looks valuable. Are they precious stones?â
âWell, theyâre not exactly diamonds.â Joe laughed. âBut they are valuable, and no mistake.â
After a quick search the boys concluded that there were no similar rocks nearby.
âThatâs strange. Where did this one come from? It doesnât look as if it belonged here,â Joe mused.
Meanwhile, Frank had been examining the ground nearby. âYou know,â he announced, âthis rock might have had something to do with Graftonâs disappearance.â
âHow?â Chet asked.
âThere may be other valuable stones containing jasper around here. Maybe Grafton and Wetherby spotted some from the air and landed to pick them up.â
Chet nodded. âAfter they had gathered them, some thugs stole the stones and got rid of Grafton and Wetherby.â The boy looked around him uneasily.
âThat could be,â Joe agreed. âBut somehow I donât think so. However, they may be prisoners.â
âWell, fellows, this sun isnât growing any cooler while we stand here. I vote we head back to the plane and take this rock along with us,â Frank suggested.
He hoisted the big stone to his shoulder, and the three started back. Now it was their blue plane that appeared to be much closer than it really was. Again they walked for some time without seeming to make progress.
âIâll take a turn,â Joe offered.
The heavy burden was shifted to his shoulder, and they went on. Finally, his face wet with perspiration, he called, âYour turn, Chet. Get a soft spot ready on your shoulder!â
With sighs and groans, the valuable rock was transferred to the beefy shoulder of Chet Morton.
âWhy did we bring this old thing!â he grumbled. âHow do we know itâs valuable?â he demanded two minutes later.
For answer, Joe simply winked at his brother.
âThis stone weighs twelve tons,â protested the burdened boy. âIsnât my turn up yet? Itâs driving me into the ground!â Chet declared a dozen
