John Lemma is also mentioned in the book “A History of the Town of Poultney, Vermont” (1875) which you can find on Google Books:
“The variety of slate found on Mr. Rogers farm is known as the sea green, and the vein extends southward. John Davis and Lewis Roberts, in 1874, opened a quarry on a lot belonging to John Lemma, and next south of the Rogers farm. Davis has brought out from this quarry both the sea green and purple varieties. S. E. Hooker purchased a lot next south of Lemma's, in 1868, with a view of opening quarries there.”
