Specimens of the third or disk-shaped type are shown in Figs. 107, 108 and 109. The first, made of sandstone, is from the Snake River Indians, was a part of Mr. D. W. Owen's collection, and was presented by him to our expedition. It is nearly of the form of a disk but has slightly bulging sides, 52 mm. long, 49 mm. wide, and 19 mm. thick. The mouth of the bowl is 13 mm. in diameter; while the opening for the stem, at right angles to it, is 9 mm. in diameter. The convex appearance of the sides or ends of the disk is due to the beveling of these surfaces near their edges. On each of these sides is an incised design. These are again mentioned under the section of art on p. 125. The second specimen, shown in Fig. 108, is oval in outline with slightly convex sides. The object is made of blue stone and was found in the Yakima Valley. It is about 52 mm. long, 41 mm. wide, and 19 mm. thick. Parallel scratches on the surface suggest that it was brought into shape by grinding with a piece of sandstone, although these marks may be interpreted as those made with a file. The opening in the bowl tapers evenly towards its base, from one of the longer edges of the discoid; while the somewhat longer drilling for the stem from one of the shorter edges of the disk, at right angles to the bore of the bowl, is of nearly the same diameter throughout. The specimen is in the collection of Mr. Louis O. Janeck of North Yakima.[335] The third specimen of this type which is shown in Fig. 109 is No. 155 in the collection of Mr. Janeck, and was also found in the Yakima Valley. It is made of stone resembling quartzite in appearance and is of a waxy, yellowish brown color. It is nearly circular in outline, almost flat on the rim, and the sides are somewhat convex. It is 45 mm. long by 40 mm. wide and 19 mm. thick. The bore of the bowl is 16 mm. in diameter at the mouth, and is somewhat larger than that of the stem, which is 10 mm. in diameter at its end, and at right angles to the bowl. Each bore tapers from its outer opening to the point of juncture. In the Nez Perce region to the east near Asotin city, this disk-shaped type of pipe is found.[336] Mr. Fay Cooper Cole of the Field Museum of Natural History believes the Tlingit have a variation of this type of pipe and that it is also found in California. Its occurrence in Oregon is mentioned by Moorehead.[337] [335] Museum negative no. 41503, 6-4. [336] Spinden, p. 189, Fig. 6, Plate IX. [337] Moorehead, Fig. 27, p. 316. The fourth or rectangular bowl type is shown in Figs. 110, 111 and 112. The first shows the axis of the bowl and that of the stein, at nearly, if not exactly, a right angle. The specimen is in the collection of Mr. York, and is made of soft grit or sandstone. The outer opening of the bowl is somewhat larger than that of the stem. There was a band around the bowl, made up of a single thickness of thread which is not shown in the figure.
