"Oh," said Roderick. "I had forgotten all about it. Yes, come in." He stepped back and the physician eyed him curiously. He looked desperately ill, sure enough. Roderick answered briefly and absently all the doctor's questions. Beside this awful thing which threatened him, his arm seemed so trivial, that he was impatient at the attention he was compelled to give it. Evidently the physician was of another opinion as to its importance. His face was imperturbable, but after a careful examination he said very gravely: "You'll have to have this attended to immediately, Mr. McRae. Immediately. It's a case, if my judgment is correct, that has been delayed much too long already. Could you come to the hospital--this morning?"' "I have to leave here on the three-fifteen this afternoon," said Roderick. "I have just received a telegram that my father is very ill--I can't have anything done to-day." "Ah, quite sad indeed. Not serious I hope?" "I don't know," said Roderick dully. "I must urge you especially to come to-day. We have Dr. Berger here, from New York. He is going to the congress at Halifax. You have heard of him, of course. He is coming to see some patients of mine this morning, and I should like him to see you too. Indeed, I feel I must urge you, Mr. McRae. You are trifling with your health, perhaps your life," he went on, puzzled by Roderick's indifference. "It is imperative that something be done at once. How about coming with me now? It leaves plenty of time for your train." Roderick considered a moment. He could not meet Mr. Graham now in any case. He must leave a message for him that he had been called back to Algonquin and telegraph home for more specific news. That was all he could do until train time, so he decided he might as well obey the doctor. When he had despatched a telegram and written a message for Mr. Graham he followed the doctor to his car. The professional man seemed eagerly delighted, as though Roderick were merely a wonderful new specimen he had found and upon which he intended to experiment. He chattered away happily on the way to the hospital. "Yes, Berger will be very much interested. Yours is really a rare case, from a medical standpoint, Mr. McRae. Quite unique. You said you believed it was injured when you were only six years old?"
