The woman went away, and Hannah lost not an instant in acting on the advice given to her.  She wrapped her old shawl round little Roy, and forgetting even to close her cellar door, went out.  The fog was less thick, and the gas made the place far brighter than it had been by day. Hannah walked briskly, for little Roy had laid his heavy head on her shoulder, and he felt cold in her arms.  But she walked with hope going before and by her side.  If the neighbour's baby, who was so much worse than Roy, might yet recover, why surely he might.  Her heart danced at the thought.  Yes, God was not going to snatch this second treasure away.  How very good she would be in future for such a loving mercy as this!  She reached the doctor's door, saw the name on the plate, and pulled the bell.  In a moment a little maid opened it.  But alas! the doctor was not at home, he was out at church, and so was the missis; he would be back in about an hour; would the woman call again in an hour? Hannah's heart sank within her; the night had turned very chilly, and little Roy, sleeping heavily in her arms, seemed to grow colder and colder; dare she keep him in the winter streets for a whole hour?
