"O. K., Professor."

With a last warm handclasp, leaving them joined in a new bond of friendship, the two men moved on over that narrow, moonlit ridge across the top of the world.


t was a desperate trail, Professor Prescott realized after scarcely a dozen steps. The ridge grew narrower, sheerer, and in places they had to straddle it, legs dangling precariously to left and right.

Admiration for his gallant companion mounted in the professor's pounding heart, as they struggled on. Only to picture anyone eager to return such a perilous way, after once getting safely back!

Other thoughts occupied his mind, too, during the next half-hour. More than once he could have sworn he saw small, ghostly figures on the ridge ahead. But he made no mention of it, for Stoddard didn't seem to see them.

Now they gained the far end of that hazardous ridge, where a sloping shelf of jagged rock offered a somewhat more secure footing. Along this they proceeded laterally for some distance.

Suddenly Stoddard paused and called out:

"Ah—there we are!" He indicated a steep pocket to the left. "Have a look down there, Professor, and tell me what you see."
