Wilbur Wade was very happy.

He had brought home complete maps and charts of the sunken isthmus, and many valuable specimens.

He was the only member of the American Society that visited the deep sea and witnessed its wonders.

He had the satisfaction of attending the next meeting of the American Society and proving his claims in regard to the Sunken Isthmus, to the utter rout and discomfiture of the fractious Professor Brown. And this was a happy triumph.

Frank Reade, Jr., Barney and Pomp are yet in Readestown. Of course, the young inventor is not idle.

But what his next invention will be we are not as yet prepared to say. Only time will tell.

But one thing is sure. None of our adventurers in this tale of the Sunken Isthmus will quite forget the incidents connected therewith.

With which statement we have reached the end of our story and with the reader’s kind permission will write adieu.

THE END.

Read “THE BLACK MOGUL; OR, THROUGH INDIA WITH FRANK READE, JR.,” which will be the next number (93) of “Frank Reade Weekly Magazine.”
