"How not? Torn off, do you mean?"

"Yes, or rather, neatly cut away; and as none of the envelopes were kept, the only means by which we can locate the writer is through this girl Doris."

Sweetwater took up the sheet Mr. Gryce pushed towards him and re-read these lines:

"It is a snowy night, but it is all bright inside and I feel no chill in mind or body. I hope it is so in the little cottage in Derby; that my little friend is as happy with harsh winds blowing from the mountains as she was on the summer day she came to see me at this hotel. I like to think of her as cheerful and beaming, rejoicing in tasks which make her so womanly and sweet. She is often, often in my mind.

"Affectionately your friend, "EDITH A. CHALLONER."

"D-o-r-i-s spells something besides Doris."
