“But if you found some of the golden images you could buy another mule—­two of ’em if you wanted that many,” said Ned, and a moment later he remembered that Tom did not want the colored man to know anything about the trip after gold.  He had been led to believe that it was merely a trip to locate an ancient city.

“Did yo’ done say golden images?” asked Eradicate, his eyes big with wonder.

Ned glanced apologetically at Tom, and said, with a shrug of his shoulders: 

“Well, I—­”

“Oh, we might as well tell him,” interrupted the young inventor.  “Yes, Rad, we expect to bring back some images of solid gold from the underground city.  If you go along you might get some for your self.  Of course there’s nothing certain about it, but—­”

“How—­how big am dem gold images, Massa Tom?” asked Eradicate eagerly.

“You’ve got him going now, Tom,” whispered Ned.

“How big?” repeated Tom musingly.  “Hum, well, there’s one that is said to be bigger than three men, and there must be any number of smaller ones—­say boy’s size, and from that on down to the real little ones, according to Mr. Illingway.”

“Real gold—­yellow, gold images as big as a man,” said Eradicate in a dreamy voice.  “An’—­an’ some big as boys.  By golly, Massa Tom, am yo’ suah ob dat?”

“Pretty sure.  Why, Rad?”

“Cause I’s gwine wid yo’, dat’s why!  I didn’t know yo’ all was goin’ after gold.  My golly I’s gwine along!  Look out ob mah way, ef yo’ please,—­Mr, Damon.  I’se gwine t’ pack up an’ go.  Am it too late to git me a ticket, Massa Tom?”

“No, I guess there’s room on the ship.  But say, Rad, I don’t want you to talk about this gold image part of it.  You can say we’re going to look for an underground city, but no more, mind you!”

“Trust me, Massa Tom; trust me.  I—­I’ll jest say brass images, dat’s what I’ll say—­brass!  We’s gwine after brass, an’ not gold.  By golly, I’ll fool ’em!”

“No, don’t say anything about the images—­brass or gold,” cautioned Tom.  “But, Rad, there’s another thing.  We may run across the head-hunters down thre in Mexico.”

“Head-hunters?  What’s dem?”

“They crush you, and chop off your head for an ornament.”

“Ha!  Ha!  Den I ain’t in no danger, Massa Tom.  Nobody would want de head ob an old colored man fo’ an ornament.  By golly!  I’s safe from dem head-hunters!  Yo’ can’t scare me dat way.  I’s gwine after some of dem gold images, I is, an’ ef I gits some I’ll build de finest stable Boomerang ever saw, an’ he kin hab oats fo’ times a day.  Dat’s what I’s gwine t’ do.  Now look out ob mah way, Mr. Damon, ef yo’ pleases.  I’s gwine t’ pack up,” and Eradicate shuffled off, chuckling to himself and muttering over and over again:  “Gold images!  Gold images!  Images ob solid gold!  Think ob dat!  By golly!”

“Think he’ll give the secret away, Tom?” asked Ned.
