At this very instant, just as the little girls set their feet on the opposite pavement, a woman carrying a child in her arms came out of the public-house; she walked unsteadily, and unheeding, probably not hearing, the rapidly approaching carriage-wheels, stepped into the street.  As she did so her ragged shawl was caught by the wind and flung aside, revealing to view a little child's blue frock, and showing for an instant a golden head pressed heavily on her bosom.  Faith saw nothing, but Meg did.  The woman was Hannah Searles; the child, little lost Roy-- she recognised him by his blue frock and golden head.  She uttered a joyful cry, and was about to touch Faith, when the sound on her lips was changed to a scream of horror.  The carriage and prancing horses were on the woman, who was too tipsy either to see them or to save herself.  In an instant she and little Roy must have been killed.  Quick, quicker than thought brave Meg rushed to the rescue.  She flew in the faces of the excited horses and caught their reins.  They swerved in their course, swerved sufficiently to enable woman and child to pass by unhurt, but they knocked Meg down and the carriage-wheels went over her.
