“Yes, one that I can not pull up.”

“Pull up!” exclaimed both Boone and Kenton, in a breath.

“Yes,” replied Lark, his breath coming thick and hard, like the breath of a hunted animal.

“Pull up a tree! Why, you ain’t got strength enough now to pull up a blackberry bush,” said Boone.

“That is true,” murmured Lark, hoarsely; “but in a few minutes I shall have the strength of a giant.”

Again Boone and Kenton looked at each other in wonder.

“This is a riddle!” cried Boone.

“Do not waste time in trying to guess it,” gasped Lark, hoarsely, “but, if you are friends of mine, do as I wish before it is too late.”

“Too late!”

“Yes, a few minutes more and it will be too late. I have had these attacks before, but never until this one did I guess what the result of the attack would be. But, now, Heaven has permitted me to have a knowledge of the truth.” Lark spoke with great difficulty, and white froth began to gather at the corners of his mouth.
