She told him. "You came to warn me!" he said. "It was very brave and unselfish of you. I am chagrined that I should have been thus surprised. The creature was up wind from me and yet I did not sense its near presence until it charged. I cannot understand it." "It is not strange," said Pan-at-lee. "That is one of the peculiarities of the GRYF--it is said that man never knows of its presence until it is upon him--so silently does it move despite its great size." "But I should have smelled it," cried Tarzan, disgustedly. "Smelled it!" ejaculated Pan-at-lee. "Smelled it?" "Certainly. How do you suppose I found this deer so quickly? And I sensed the GRYF, too, but faintly as at a great distance." Tarzan suddenly ceased speaking and looked down at the bellowing creature below them--his nostrils quivered as though searching for a scent. "Ah!" he exclaimed. "I have it!" "What?" asked Pan-at-lee. "I was deceived because the creature gives off practically no odor," explained the ape-man. "What I smelled was the faint aroma that doubtless permeates the entire jungle because of the long presence of many of the creatures--it is the sort of odor that would remain for a long time, faint as it is. "Pan-at-lee, did you ever hear of a triceratops? No? Well this thing that you call a GRYF is a triceratops and it has been extinct for hundreds of thousands of years. I have seen its skeleton in the museum in London and a figure of one restored. I always thought that the scientists who did such work depended principally upon an overwrought imagination, but I see that I was wrong. This living thing is not an exact counterpart of the restoration that I saw; but it is so similar as to be easily recognizable, and then, too, we must remember that during the ages that have elapsed since the paleontologist's specimen lived many changes might have been wrought by evolution in the living line that has quite evidently persisted in Pal-ul-don." "Triceratops, London, paleo--I don't know what you are talking about," cried Pan-at-lee.
