 The furnace was built in 1772, under the eye of its experienced owner, and was in good working order when the Revolutionary war broke out.We have not a letter book giving the details of its operations, but from the frequent reference to Mr. FAESCH in HOFF's letters from Hibernia, as well as from other sources, it is certain that large quantities of cannon, shot and iron utensils were manufactured there and that more men were employed than at Hibernia.The tories made many attempts to rob the house of FAESCH at Mount Hope and to destroy his property; but after the battle of Trenton and the capture of the Hessians, it is said, he made an arrangement with General WASHINGTON to keep thirty of the prisoners until the close of the war.
