Mr. Gordon did not see Mary when she came in. He was standing at his desk, with an open letter in his hand, and his face was disturbed as he spoke to the senior clerk.

"Myers, it is as I feared about that bag of rags from Blankton. You have kept it carefully tied up, and close by the chlorides, as I told you?"

Myers, a clear-eyed, honest-browed man, looked troubled.

"I did, sir!" he said. "I have looked at the bag every time I passed that way, and have cautioned every one in the mill not to go near it, besides keeping the shed-gate locked; but this morning I found that it had been tampered with, and evidently something taken out. I hope there is nothing wrong, sir!"

George Gordon struck his hand heavily on the desk. "Wrong!" he repeated. "There have been two fatal cases of smallpox in Blankton, and that bag has been traced to the house where they were."

There was a moment of deathly silence. He went on:

"I suspected something wrong, the moment you told me of things that looked new and good; but I did not want to raise a panic in the mill, when there might be some other explanation. I thought I had taken every precaution—what is that?"

He turned quickly, hearing a low cry behind him. Mary Denison was standing with clasped hands, her face white with terror.

"Mary!" said Mr. Gordon, in amazement. "You—surely you have had nothing to do with this?"

"No, sir!" cried Mary. "Oh, no, Mr. Gordon, indeed I have not. But I fear—I fear I know who has. Oh, poor thing! poor Lena!"
