Famous quotes containing the word july:
“This, it will be remembered, was the scene of Mrs. Rowlandson’s capture, and of other events in the Indian wars, but from this July afternoon, and under that mild exterior, those times seemed as remote as the irruption of the Goths. They were the dark age of New England.”
