Hal looked extremely crestfallen and remorseful.

"I'm always getting jars."

It took a whole day for him to recover his usual spirits.

Ken had promptly sent the specimens and his notes to his uncle, and as the days passed the boys began to look anxiously for some news. In ten days Hal was as well as ever, and then the boys had such sport with the tarpon and big sharks and alligator-gars that they almost forgot about the rewards they had striven so hard for and hoped to win. But finally, when the mail arrived from home, they were at once happy and fearful. George was with them that evening, and shared their excitement and suspense. Hal's letters were from his mother and his sister, and they were read first. Judge Ward's letter to Ken was fatherly and solicitous, but brief. He gave the boys six more weeks, cautioned them to be sensible and to profit by their opportunity, and he inclosed a bank-draft. Not a word about rewards!

Ken's fingers trembled a little as he tore open the uncle's letter. He read it aloud:

DEAR KEN,--Congratulations! You've done well. You win the trip to Africa. Hal's work also was good--several specimens accepted by the Smithsonian. I'll back you for the Yucatan trip. Will send letters to the American consul at Progreso, and arrange for you to meet the Austrian archæologist Maler, who I hope will take you in hand.

I want you to make a study of some of the ruins of Yucatan, which I believe are as wonderful as any in Egypt. I advise you to make this trip short and to the point, for there are indications of coming revolution throughout Mexico.

With best wishes,

UNCLE G.

The old varsity cheer rang out from Ken, and Hal began a war-dance. Then both boys pounced upon George, and for a few moments made life miserable for him.
