But I spoke up, and sez, " Truly rags will be always here with us, and most likely butnut and copperas; but the World's Fair comes but once in a lifetime, and I believe in embracin' it now, and makin' the most of it."- "Samantha at the World's Fair", Marietta Holley.
For instance: if drain pipes run through the cellar, have them examined often for leaks; if there is an open drain, wash it out frequently with copperas and water, and give it an occasional flushing with chloride of lime or lye in strong solution to destroy any possible odor arising from it; and see that the roof drains do not empty too near the house, thus dampening the cellar walls.- "The Complete Home", Various.
