"He is sleeping upstairs. Shall I call him?"
"No. Take me to his room."
The President"s naval physician opened the door in response to Bolton"s knock.
"Is he worse?" he demanded anxiously.
"I don"t think so, Admiral," replied Bolton. "I want to introduce you to Dr. Bird of the Bureau of Standards. He wants to talk with you about the case."
"I am honored, Doctor," said the physician as he grasped the scientist"s outstretched hand. "Come in. Pardon my appearance, but I was startled out of a doze when you knocked. Have a chair and tell me how I can serve you."
Dr. Bird drew a notebook from his pocket.
"I have received certain dates in connection with the President"s malady from Operative Carnes," he said, "and I wish you to verify them."
"Pardon me a moment, Doctor," interrupted the Admiral, "but may I ask what is your connection with the matter? I was not aware that you were a physician or surgeon."
"Dr. Bird is here by the authority of the secret service," replied Bolton. "He has no connection with the medical treatment of the President, but permit me to remind you that the secret service is responsible for the safety of the President and so have a right to demand such details about him as are necessary for his proper protection."
"I have no intention in obstructing you in the proper performance of your duties, Mr. Bolton," began the Admiral stiffly.
"Pardon me, Admiral," broke in Dr. Bird, "it seems to me that we are getting started wrong. I suspect that certain exterior forces are more or less concerned in this case and I have communicated my suspicions to Mr. Bolton. He in turn brought me here in order to request from you your cooperation in the matter. We have no idea of demanding anything and are really seeking help which we believe that you can give us."
"Pardon me, Admiral," said Bolton. "I had no intention of angering you."
"I am at your service, gentlemen," replied Admiral Clay. "What information did you wish, Doctor?"
"At first merely a verification of the history of the case as I have it."
Dr. Bird read the notes he had taken down from Carnes and the Admiral nodded agreement.
"Those dates are correct," he said.
"Now, Admiral, there are two further points on which I wish enlightenment. The first is the opthalmia which is troubling the patient."
"It is nothing to be alarmed about as far as symptoms go, Doctor,"
replied the Admiral. "It is a rather mild case of irritation, somewhat a.n.a.logous to granuloma, but rather stubborn. He had an attack several weeks ago and while it did not yield to treatment as readily as I could have wished, it did clear up nicely in a couple of weeks and I was quite surprised at this recurrent attack. His sight is in no danger."
"Have you tried to connect this opthalmia with his mental aberrations?"
"Why no, Doctor, there is no connection."
"Are you sure?"
"I am certain. The slight pain which his eyes give him could never have such an effect upon the mind of so able and energetic a man as he is."
"Well, we"ll let that pa.s.s for the moment. The other question is this: has he any form of skin trouble?"
The Admiral looked up in surprise.
"Yes, he has," he admitted. "I had mentioned it to no one, for it really amounts to nothing, but he has a slight attack of some obscure form of dermat.i.tis which I am treating. It is affecting only his face and hands."
"Please describe it."
"It has taken the form of a brown pigmentation on the hands. On the face it causes a slight itching and subsequent peeling of the affected areas."
"In other words, it is acting like sunburn?"
"Why, yes, somewhat. It is not that, however, for he has been exposed to the sun very little lately, on account of his eyes."
"I notice that he is sleeping in the new solarium which was added last winter to the executive mansion. Can you tell me with what type of gla.s.s it is equipped?"
"Yes. It is not equipped with gla.s.s at all, but with fused quartz."
"When did he start to sleep there?"
"As soon as it was completed."
"And all the time the windows have been of fused quartz?"
"No. They were glazed at first, but the gla.s.s was removed and the fused quartz subst.i.tuted at my suggestion about two months ago, just before this trouble started."
"Thank you, Admiral. You have given me several things to think about. My ideas are a little too nebulous to share as yet but I think that I can give you one piece of very sound advice. The President is spending a very restless night. If you would remove him from the solarium and get him to lie down in a room which is glazed with ordinary gla.s.s, and pull down the shades so that he will be in the dark, I think that he will pa.s.s a better night."
Admiral Clay looked keenly into the piercing black eyes of the Doctor.
"I know something of you by reputation, Bird," he said slowly, "and I will follow your advice. Will you tell me why you make this particular suggestion?"
"So that I can work in that solarium to-night without interruption,"
replied Dr. Bird. "I have some tests which I wish to carry out while it is still dark. If my results are negative, forget what I have told you.
If they yield any information, I will be glad to share it with you at the proper time. Now get the President out of that solarium and tell me when the coast is clear."
The Admiral donned a dressing gown and stepped out of the room. He returned in fifteen minutes.
"The solarium is at your disposal, Doctor," he announced. "Shall I accompany you?"
"If you wish," a.s.sented Dr. Bird as he picked up his apparatus and strode out of the room.
In the solarium he glanced quickly around, noting the position of each of the articles of furniture.
"I presume that the President always sleeps with his head in this direction?" he remarked, pointing to the pillow on the disturbed bed.
