dership could hear Mr.
Chadwick's voice.

Then followed a long conversation between father and son. Mr. Chadwick
had almost completely recovered his health, and was again working over
new experiments. Dick insisted that he be permitted to tell the story
of their adventures on the island of the Coloradite Treasure.

"You won't tell it right," he declared to Jack, and insisted so
strenuously that the boy inventor had to let him speak to Mr.
Chadwick.

Dick set his choicest language agoing, and his vivid description of
Jack's part in every incident was embellished by the most flowery
adjectives in his vocabulary. Jack had to listen, and grin.

By the time his long story was done, Nestorville was sighted. As soon
as the people saw the Wondership, pandemonium broke loose. Not only
Nestorville, but officials and crowds from the neighboring towns had
poured in, and the reception the boys and the professor received
lingered with them for many, many years.

Later, as time went on, Mr. Chadwick's fortune was completely
rehabilitated. Professor Jenks no longer was so eager to search for
rocks, and while doing so get into all sorts of difficulties. He lived
more at home, becoming at last, as his spinster sister declared, "a
man with the proper spirit to make an ideal husband." Of course, the
professor had received a very substantial sum of money from the boys.

Jack and Tom soon found themselves wealthy, and often in fancy trace
the days back to that afternoon when they found the sturdy miner lying
on the roadside, having been knocked unconscious by Masterson's
careless driving of his automobile.

Zeb, continued to take charge of the work on Rattlesnake Island, to
which the boys never returned. For a long time the supply from the
black barren appeared to be inexhaustible. Suddenly, however, it
ceased, and no more was dug. But what had been mined had been more
than sufficient to make all prosperous.

Dick, with his share of the proceeds, which the boys insisted that he
accept, bought the _Nestorville Bugle_. From the very start, he made
it a live, progressive paper. Sometimes, when the now busy editor had
a spare hour, he invariably visited his two friends, and the
three--sometimes, too, the little professor joined them
unexpectedly--recounted old-time stories.

But the boys were not made lazy by wealth and fame. To this very day,
Jack and Tom, with Mr. Chadwick's aid, are devising many inventions
calculated to benefit m
