The two retired early. Ralph, worn out by his day's travels, soon fell asleep.
It was nearly two o'clock in the morning when Mrs. Nelson called him.
"It is too bad, Ralph," she said. "But I cannot stand it any longer."
"What is it, mother, the pain in your side?" he asked, springing up.
"Yes. It is growing worse, and I must have something for it."
"Shall I go for Dr. Foley?"
"You may go to his house. Tell him what is the trouble, and ask him to give you a plaster or some liniment for it."
"I will. You are not afraid to stay alone while I am gone?"
"Oh, no, only hurry as fast as you can."
"I will," replied Ralph, quickly.
