The typical mound pipe is the Monitor form, as it may be termed, possessing a short, cylindrical urn, or spool-shaped bowl, rising from the center of a flat and slightly-curved base. [Footnote: For examples of this form see Rau: Smithsonian Contributions to Knowledge, No. 287, p. 47, Fig. 177.] Accepting this statement as proof that the "Monitor" pipe is generally understood to be the oldest type of the mound-builders' pipe, it is easy to trace the modifications which brought into use the simple form of the modern Indian pipe. For example, there is one of the form shown in Fig. 5, from Hamilton County, Ohio; another from a large mound in Kanawha Valley, West Virginia; [Footnote: Science. 1884, vol. 3, p. 619.] several taken from Indian graves in Essex County, Mass.; [Footnote: Abbott, Prim. Industry, 1881, Fig. 313, p. 319; Bull. Essex Inst., vol. 3, 1872, p. 123.] another found in the grave of a Seneca Indian in the valley of the Genesee; [Footnote: Morgan, League of the Iroquois, p. 356.] and others found by the representatives of the Bureau of Ethnology in the mounds of western North Carolina. [Illustration with caption: FIG. 5. Pipe from Hamilton County, Ohio.] So far, the modification consists in simply shortening the forward projection of the stem or base, the bowl remaining perpendicular. The next modification is shown in Fig. 6, which represents a type less common than the preceding, but found in several localites, as, for example, in Hamilton County, Ohio; mounds in Sullivan County, east Tennessee (by the Bureau); and in Virginia. [Footnote: Rau: Smithsonian Contributions to Knowledge, No. 287, p. 50, Fig. 190.] In these, although retaining the broad or winged stem, we see the bowl assuming the forward slope and in some instances (as some of those found in the mounds in Sullivan County, Tenn.) the projection of the stem is reduced to a simple rim or is entirely wanting.

Pipe from Sullivan County, Tennessee.] The next step brings us to what may be considered the typical form of the modern pipe, shown in Fig. 8. This pattern, according to Dr. Abbott, [Footnote: Prim. Industry, 1861, p. 329.] is seldom found in New England or the Middle States, "except of a much smaller size and made of clay." He figures one from Isle of Wight County, Va., "made of compact steatite." A large number of this form were found in the North Carolina mounds, some with stems almost or quite a foot in length.
