Because the partition was only one thickness of boards she heard them commenting one night on the grim fact that no smoke had been seen at Taylor Rock, though many eyes had watched anxiously for the sign.  She listened, and she knew that they were going to give up—­knew that they should have given up long ago but for her.  With no fire in the cave none could live for long in this weather, she heard them muttering.  The cave was drifted full of snow, in the opinion of those who had the most experience with mountain snows.  The lost couple might be in the cave, but they were not alive.  One man said that they were probably under some fallen tree—­and they were many—­or buried deep in a gulch somewhere.  Certainly after ten days neither Jack nor Marion nor Mike could by any possibility be alive in the hills.

Kate was asleep and did not hear.  The professor was out there with the others—­probably they thought that Mrs. Singleton Corey was asleep also, for it was growing late.  Her chapped knuckles pressed against her trembling lips, she listened awhile, until she could bear no more.  How kind they were—­these men of Quincy!  How they had struggled to keep alive her courage!  She got up, opened the door very quietly, and went out into the strong, bluish haze of tobacco smoke that enveloped the men huddled there around the kitchen stove for a last pipe before they turned in.  She stood within the door, like “madam president” risen to address the meeting.  Like “madam president” she waited for their full attention before she spoke.

“I wish to thank you gentlemen for the heroic efforts you have put forth during the past week,” she said, and her low-pitched voice had the full resonance that was one of her charms as a leader among women.  “It would be impossible for me to express my grateful appreciation—­” She stopped, pressed her lips together for a minute, and when she felt sure of her composure she made a fresh start.  “I cannot speak of the risks you have taken in these forests, but I—­I appreciate your bravery.  I know that you have been in danger from falling trees, nearly every day that you spent searching for—­those who are lost.  I have learned from your conversations among yourselves how useless you consider the search.  I—­I am forced to agree with you.  Miss Humphrey and Professor Harrison have long ago given up all hope—­they say that—­that no one could possibly be alive....  I—­I know that a mother can be terribly selfish when her son....”  Hard as she fought for steadiness, she could not speak of it.  She stood with the back of one hand pressed hard against her shaking lips, swallowing the sobs that threatened to balk her determination to speak a little of the humble gratitude that filled her.  The men looked down in embarrassed silence, and in a minute she went on.

“Gentlemen, I know that you have gone on searching because you felt that I wanted you to do it, and you were too kind-hearted to tell me the truth.  So I beg of you now to go back to your families.  I—­I must not let my trouble keep you away from them any longer.  I—­I—­have given up.”
