"How are you going to do it?"

"I'm going to get Professor Henderson and Professor Roumann to
translate this article for you, and then you can ask them what Reonaris
is. Guess that'll convince you; won't it?"

"Maybe; but why don't you ask Andy Sudds or Washington White to give
their opinion?"

"Don't get funny," advised the other lad sharply, and then, seeing that
his chum was smiling, Jack laughed, cooled down a bit, looked at the
paper which he had crumpled in his hand, and said:

"I guess I _was_ getting a little too excited. But I'm sure I'm right.
Here's the paper I brought from Mars to prove it, and the only thing
there's any doubt about is whether or not Reonaris means diamonds. I'll
ask----"

At that moment the door of the library, in which Jack and Mark were
seated, was cautiously opened, and a black, woolly head was thrust in.
Then two widely-opened eyes gazed at the boys.

"What's the matter, Washington?" asked Jack, with a laugh.

"'Scuse me, Massa Jack," answered the colored man, "but did I done heah
you' to promulgate some conversationess regarding de transmigatorability
ob diamonds?"

"Do you mean, were we talking about diamonds?" inquired Mark.
