There is a broad, shallow constriction at the neck. The walls are from one-fourth to three-eighths of an inch thick, and the margin of the rim is squared off, showing the full thickness--a strong characteristic of the northern pottery. The form is nearly symmetrical, and the surface is hand-smoothed but not polished. The paste is now dark and crumbling, and shows a rough fracture. A large percentage of sand was used in tempering. The color is a dark gray-brown. The entire surface, with the exception of a narrow band about the base, has been covered with ornamentation. This is executed with considerable care, and shows a great deal of ingenuity and some taste. There is apparently no feature copied from nature or from ideographic art. Two or three distinct implements have been used. A part of the neck ornament was made by rolling back and forth a circular tool, a _roulette_, the edge of which was notched. A row of indented nodes has been produced upon the exterior surface of the neck by impressing upon the inside the end of a reed or hollow bone about one-fourth of an inch in diameter. Patterns of bold, rather carelessly drawn lines cover the body and seem to have been made by trailing, under pretty strong pressure, the smooth point of a stylus--probably the bone or reed already suggested. Some of the larger indentations upon the lower part of the neck may have been made by the same implement held in an oblique position. The use to which this vessel was applied can hardly be guessed. It was found with the remains of its owner, and probably contained food or drink. [Illustration: FIG. 456.--Vase: Davenport, Iowa.--1/3.] Another smaller vessel from the same locality and found under similar conditions shows the same characteristics of material, form, and ornament. There are also a few other fragments of the same ware from this group of mounds. One of these shows that decoration by the indentation of twisted cords was practiced here as elsewhere. A similar vase tastefully decorated with indented lines about the neck, and a band of decoration consisting of broad, plain, sinuous bands upon the body, comes from a mound in Scott County, Iowa. Height six inches, diameter the same. The rims of all these vessels are square on the edge, showing the full thickness of the walls. [Illustration: FIG. 457.--Vase: Wisconsin.--1/2.
