"I stay here teel Senor Glendon and Juan come home. El Doctor say 'stay.'" "But, Chappo," she protested, "they may be away a week or more. You must go home and look out for the doctor." "El Padrone say 'stay.' I must stay. He say, 'you come home too queek, I fire you;'" the Mexican smiled expansively, "Eet is all right, Senora. I stay!" She realized that her objections were of no consequence to either the Mexican or the doctor, and a sudden wave of gratitude overwhelmed her. It was so new to have others think of her comfort or safety, to have the heavy burden lifted even for a few hours. What a difference it would have made in her life and Donnie's if Glendon were only a man like the doctor. Then there would have been no loneliness in the canyon, for the high walls could not have held her happiness. Her heart would have sent its message to every tree, bush, rock, bird and cloud, so that the very universe might share her joy. Early the next morning Donnie was on the watch for his new friend, and his delight made him speechless when Powell told the boy that the pony tied to the back of the buggy was for him. "He is too small to carry a man's weight," explained Powell, "but he is perfectly gentle, so you need have no fear." "I can't let you do so much," faltered Katherine, "the dog was more than enough. You are heaping a debt of obligations that I cannot pay. Last night I tried to make Chappo go home, but he refused. He said you had ordered him to remain, and that you would discharge him if he disobeyed you. I know how many things need attention on a ranch and it worries me to cause you any further inconvenience. Donnie and I are used to being alone, you see, so there was no need of Chappo staying here all night." "You must think I am a regular tenderfoot," retorted Powell, smiling. "I have roughed it under the most primitive conditions in South America, and am glad to do a bit of hustling to wear off the rust. Civilization makes many men helpless, you know." "Then, let us compromise," she persisted. "Suppose you come down for your dinner each night while Chappo is here? I cannot consent to his remaining otherwise." "Do you know," confessed Powell gaily, "that was what I was hoping you would say!" So, each afternoon following, when the shadows lengthened in the canyon, Donnie, watching down the road would shout welcome, and Katherine coming on the porch, watched Doctor Powell pause at the bend of the road, waiting for the child, just as old Doctor King had formerly done, then Donnie, perched on the saddle before the doctor, rode in state to the front porch and his smiling mother. On one of these rides, Donnie looked with serious eyes at the man, and said, "When I grow up, I'm going to be a doctor like you, and then, maybe, you'll let me come and help you. Marmee says that helping others is just the same as fighting in tour'ments or hunting the Sangreal!"
