No one point, probably, has yielded more than the farm and immediate neighborhood of Dr. C. C. Abbott (heretofore referred to), at Trenton, New Jersey. This farm occupies a bluff and wide meadows facing the Delaware River. It was a location unexcelled in advantages for the mild-mannered, sunshine-loving Leni-Lenape. On the dry high ground they could build their lodges underneath great trees and find themselves upon the highway of travel, while the rich bottom-lands gave them never-exhausted planting-ground for their fields of maize. Better than all, they could overlook not only these fields, but far away down the river, and scan the approach of strangers, or watch the approach of the returning parties of hunters and fishermen, whose canoes came up the creeks to moorings at the very foot of the bluff. That this spot was long tenanted by an Indian village there seems ample proof. Almost every species of Indian handiwork, in stone, bone, and clay, known to the Atlantic coast has been found in and about this farm during the past ten years, and the total yield of a square mile in that locality has been nearly twenty-five thousand specimens. The great majority of these are now in the Peabody Museum, and they have furnished Dr. Abbott with the material for our most valuable book on the stone age in North America, entitled "Primitive Industry" (George A. Bates, Salem, 1881). They consist of varied series of axes, celts, hammers, bolas, knives, drills, scrapers, mortars and pestles, food-vessels and agricultural tools, fishing- and hunting-implements, spear- and arrow-points, club-heads, daggers, and other weapons, pipes and gaming-stones, ceremonial and ornamental objects,--all of stone,--besides a deal of pottery (chiefly in fragments), bone-work, and implements of copper, probably procured from other tribes.
