I'm only tired." She saw him into his room, and, according to her usual custom, put a handbell on the small table which was at the side of his bed.

Charlie, trotting at her heels, suddenly began to whimper.

She stooped and picked the little creature up in her arms.
"Mind you ring if you want me," she said to Helmsley then,--"I'm just above you, and I can hear the least sound." He looked at her earnestly.

His eyes were almost young in their brightness.
"God bless you, Mary!" he said--"You've been a good angel to me! I never quite believed in Heaven, but looking at you I know there is such a place--the place where you were born!" She smiled--but her eyes were soft with unshed tears.
"You think too well of me, David," she said.

"I'm not an angel--I wish I were! I'm only a very poor, ordinary sort of woman." "Are you ?" he said, and smiled--"Well, think so, if it pleases you.
Good-night--and again God bless you!" He patted the tiny head of the small Charlie, whom she held nestling against her breast.
"Good-night, Charlie!" The little dog licked his hand and looked at him wistfully.
"Don't part with him, Mary!" he said, suddenly--"Let him always have a home with you!" "Now, David! You really are tired out and over-melancholy! As if I should ever part with him!" And she kissed Charlie's silky head--"We'll all keep together! Good-night, David!" "Good-night!" he answered.
