“Honduras, as you of course know, is a republic of Central America, and it gets its name from something that happened on the fourth voyage of Columbus.  He and his men had had days of weary sailing and had sought in vain for shallow water in which they might come to an anchorage.  Finally they reached the point now known as Cape Gracias-a-Dios, and when they let the anchor go, and found that in a short time it came to rest on the floor of the ocean, some one of the sailors—­perhaps Columbus himself—­ is said to have remarked: 

“`Thank the Lord, we have left the deep waters (honduras)’ that being the Spanish word for unfathomable depths.  So Honduras it was called, and has been to this day.

“It is a queer land with many traces of an ancient civilization, a civilization which I believe dates back farther than some in the far East.  On the sculptured stones in the Copan valley there are characters which seem to resemble very ancient writing, but this pictographic writing is largely untranslatable.

“Honduras, I might add, is about the size of our state of Ohio.  It is rather an elevated table-land, though there are stretches of tropical forest, but it is not so tropical a country as many suppose it to be.  There is much gold scattered throughout Honduras, though of late it has not been found in large quantities.

“In the old days, however, before the Spaniards came, it was plentiful, so much, so that the natives made idols of it.  And it is one of the largest of these idols—­by name Quitzel—­that I am going to seek.”

“Do you know where it is?” asked Ned.

“Well, it isn’t locked up in a safe deposit box, of that I’m sure,” laughed the professor.  “No, I don’t know exactly where it is, except that it is somewhere in an ancient and buried city known as Kurzon.  If I knew exactly where it was there wouldn’t be much fun in going after it.  And if it was known to others it would have been taken away long ago.

“No, we’ve got to hunt for the idol of gold in this land of wonders where I hope soon to be.  Later on I’ll show you the documents that put me on the track of this idol.  Enough now to show you an old map I found, or, rather, a copy of it, and some of the papers that tell of the idol,” and he spread out his packet of papers on the table in front of him, his eyes shining with excitement and pleasure.  Mr. Damon, too, leaned eagerly forward.

“So, Tom Swift,” went on the professor, “I come to you for help in this matter.  I want you to aid me in organizing an expedition to go to Honduras after the idol of gold.  Will you?”

“I’ll help you, of course,” said Tom.  “You may use any of my inventions you choose—­my airships, my motor boats and submarines, even my giant cannon if you think you can take it with you.  And as for the money part, Ned will arrange that for you.  But as for going with you myself, it is out of the question.  I can’t.  No Honduras for me!”
