People had acquired the habit of speaking of her in this way, in order to distinguish her from another Mary who lived with Mrs.Bell for several years.

This other Mary was Mary Erskine.

Mary Erskine did not live now at Mrs.Bell's, but at another house which was situated nearly two miles from Mrs.Henry's, and the way to it was by a very wild and unfrequented road.

The children were frequently accustomed to go and make Mary Erskine a visit; but it was so long a walk that Mrs.Henry never allowed them to go unless on a very cool day.
At breakfast that morning Phonny asked his mother if that would not be a good day for them to go and see Mary Erskine.

Mrs.Henry said that it would be an excellent day, and that she should be very glad to have them go, for there were some things there to be brought home.
