A specimen from Jackson county, Illinois, has had a portion of the edge broken squarely. The polish over this fractured surface shows that it was long used after breaking without being rechipped to a sharp edge. This indicates usage only in loose ground, as it evidently would be quite difficult to force the square, broken part into a hard soil or tough sod.
The specimens from Polk county, Tennessee, are pecked or chipped, or both, and are quite roughly made. They are neither scratched nor polished, and may be unfinished implements of some other class, though agreeing closely with the flint spades in shape and size.
C. A modification of the last form has the upper portion chipped away along the sides until it is ovoid, with a blunt point, leaving the lower part a regular curve. An example, shown in [figure 171], is of grayish brown flint, from Scott county, Missouri. There are also one each from Mississippi county, Missouri, and Hopkins county, Kentucky, of the same material.
D. Like the above, but much shorter in ratio to the width, and with a flatter curve. The type, [figure 172], is of yellow flint, from a mound in Obion county, Tennessee. There are also three from Union county, Illinois, one of them with almost the same dimensions.
E. Semicircular outline, with sides notched for securing the handle, as in arrowpoints and spearheads. Represented by [figure 173], showing a specimen of gray flint from a mound in Mississippi county, Arkansas. There are four additional specimens, all from Union county, Illinois.
F. A related form, also notched for attachment of handle. [Figure 174] represents an example of yellow flint, from Poinsett county, Arkansas, the only one of this shape in the collection.
From Jackson county, Illinois, there is a series beginning with a small scraper and a small scraper-like celt, and passing gradually into the large spades or digging-tools, there being a number of intermediate forms and sizes. Two specimens, only 6 inches long, have the glazed surface so characteristic of these implements, which could have been produced only by long-continued use in digging.
