From mound-building I turn again to North American flint implements. Mr. Stevens refers in his work to the absence of flint scrapers in the series from the United States exhibited in the Blackmore Museum. Scrapers of the European spoon-shaped type, however, are not as scarce in the United States as Mr. Stevens seems to suppose. The collection of the Smithsonian Institution contains a number of them; and I found myself two characteristic specimens in the Kjoekkenmoedding at Keyport, New Jersey, described by me in the Smithsonian report for 1864. They lay upon the shell-covered ground, a short distance from each other, and were perhaps made by the same hand. In Fig. 4 I give a full-size drawing of one of my specimens, both of which consist of a brown kind of flint, such as probably would be called jasper by mineralogists. The figured specimen, it will be seen, possesses all the characteristics of a European scraper. Its lower surface is formed by a single curved fracture. The rounded head is somewhat turned toward the right, a feature likewise exhibited in the other specimen, which is a little larger, but not quite as typical as the original of Fig. 4. As the peculiar curve of the broad part is observable in both specimens, it must be considered as having been produced intentionally. Indeed, I have among my flint scrapers from the pilework at Robenhausen one which is curved in the same direction. In fashioning their implements in this particular manner, the Indian and the ancient lake-man possibly had the same object in view. [Illustration: Fig. 6.]
