“Ah!” exclaimed Mr. Kearns maliciously, “shall I throw the taunt in your teeth, which the little Doctor threw into mine: that you are afraid?”
“I will answer you this way,” replied the Professor calmly. “To-morrow you and I are going out together in company of the Doctor. Should you decide at any time to-morrow while we are together to enter upon an adventure of this character, you will not find me loth to join you. When people start out together in any enterprise, it is a maxim with me that they should stand shoulder to shoulder.”
“Spoken like a brick!” declared Mr. Kearns with enthusiasm.
“No,” answered the Professor dryly; “it is a conceded fact that bricks do not talk. You are really becoming more wonderful than the Doctor in your assertions!”
CHAPTER II
“SLEEP ON, MY FRIENDS, SLEEP ON”
At the time appointed on the following day—it was the tenth of June, 1900—Dr. Jaquet called for them and they started on one of their customary walks. The Doctor acted as guide. His course lay inland, in a northwesterly direction, and the trio marched jauntily on, chatting gaily together, until some four miles had been covered. Then the Doctor changed his course and they struck across country through land which was somewhat rocky and broken and thickly covered with scrub bushes and trees of a stunted growth.
“Halloa!” exclaimed Mr. Kearns, “this is pretty rough walking. Remember, too, we have the return journey. What is the use of wearing ourselves out going over ground like this?”
“Follow me,” urged Dr. Jaquet, who was leading and picking the way with care.
“Well, tell us at least where you are leading us,” said Mr. Kearns. “It’s wild enough here never to have been trodden upon by the foot of man.”
Thus questioned, the Doctor explained that he was leading the way to a little tract of land which he owned in the midst of this wilderness of scrub growth, apparently abandoned entirely to the squirrels and the jack-rabbits. He told how he had one day explored this land and had, by the sheerest accident, discovered a natural cave possessing some wonderful peculiarities. He decided to buy the land upon which it was located, and had acquired it for a mere song as it was practically valueless for any purpose whatsoever. He had kept the cave a secret for fear of its being visited by intruders. They, too, must promise him to keep the matter secret. Patience! The ground was rough, but they would soon be there.
