So turning on the power again he sent the motor flying down the road. Three-quarters of a mile further he came to the first house. There was a sign on it:

Dr. John Rand.

“Is the doctor in?” gasped Jerry, barely able to stand as he leaped from his machine and rang the bell which was answered by a woman.

“Yes, right in his office,” was the answer.

“Tell him he’s wanted at once! Mrs. Johnson is dying!”

“But I can’t get across the bridge; it is broken,” said Dr. Rand, who had come from his office in time to hear Jerry’s message.

“I got across,” exclaimed the boy. “Quick, doctor! You must hurry! Take a long plank along and you can get over the gap!”

“But if I did get across, how am I to get my horse over? He can’t walk a plank,” objected the medicine man. “It will take a long time for me to walk to Mrs. Johnson’s.”

Once more it looked as if Jerry had failed.
