ey. The latter came forth holding a slip of paper
in his hand, and, to the chauffeur, he said:

"Do you know where Dr. Baird lives?"

"Oh, yes, sir."

"Take me there, please. He was one of the physicians called in when Mr.
Carwell was poisoned, was he not?"

"Yes," and the chauffeur nodded and smiled. "You are not ill, I hope,
monsieur. If you are, there is a physician nearer--"

"Oh, no. I'm all right. I just want to have a talk with the doctor. Did
you ever consult him?"

"Me? Oh, no, monsieur, I have no need of a doctor. I am never sick. I
feel most excellent!" and certainly he looked it. There was a sparkle
in his eyes--perhaps too brilliant a sparkle, but he did not look like a
"dope fiend."

"If you are in a hurry," went on the chauffeur, "I can--"

"No, no hurry," responded the colonel. "Why, do you feel like driving
fast?"

"Very fast, monsieur. I always like to drive fast, only there is seldom
call for it. Mr. Carwell, he at times would like speed, and again he was
like the tortoise. But as for me--poof! What would you?" and he shrugged
his shoulders and reverted to his own tongue.

"Hum," mused the colonel. "Rather a different story from the garage
man's. However, we shall see."

Dr. Baird was in. In fact, being a very young doctor indeed, he was
rather more in than out--too much in to suit his own inclination and
pocketbook, for, as yet, the number of his patients was small.

"I did not come to see you for myself, professionally," said Colonel
Ashley, as he took a seat in the office, and introduced himself. "I
am trying to establish, for the satisfaction of Miss Carwell, that her
father was not a suicide, and--"

"What else could it be?" asked Dr. Baird.

"I do not know. But I read with great interest the interview, you gave
the Globe on the effects and detection of various poisons."

"Yes?" and young Dr. Baird rubbed his hands in delight, and stroked his
still younger moustache.

"Yes. And I called to ask what poison or chemical symbol that might be."

The colonel extended a paper on which was inscribed: 58 C. H.--I6I*

"That! Hum, why that is not a chemical symbol at all!" promptly declared
Dr. Baird.

"Are you sure?"

"Positive."

"Could it be some formula for poison?"

"It could not. Of course that is not to say it could not be some
person's private memorandum for some combination of elements. C might
stand for carbon and H for hydrogen. But that would not make a poison in
