In a quote from The Slate Roof Bible, (Jenkins, 1997) a Professor Agassiz in the late 1800's remarked to a quarryman, Mr. Humphrey, "The Almighty might have made more perfect fish than the trout, but He never did." In reply, the quarryman said, "I say the same for Peach Bottom slates."
Anyone who has transversed the slate walkways on Main Street through Cardiff, Maryland and Delta, Pennsylvania, and seen the slate roofs on so many buildings throughout the area including the Harkins Funeral Home would have to agree with Mr. Humphrey. In many references, Peach Bottom slate is considered to be of the highest quality, lasting hundreds of years. The foundations, roofs and walkways are proof of its durability.
