[Illustration: Fig. 19. Mortar made of Stone. From the Yakima Reservation near Union Gap. 1/2 nat. size. (Drawn from photograph 44455, 2-4. Original in the collection of Mr. Janeck.)] A somewhat disk-shaped pebble of gray lava 295 mm. in diameter with a saucer-shaped depression in the top and a large pecked pit in the bottom (20.0-3344) was collected at Fort Simcoe by Dr. H. J. Spinden. A fragment of a mortar about 190 mm. in diameter with a nearly flat or slightly convex base and a depression 50 mm. deep in the top (202-8293) was found on the surface near the head of Priest Rapids and another fragment nearly twice as large, the base of which is concave over most of its surface and shows marks of pecking, apparently the result of an attempt to make it either quite flat or concave like many other mortars that have a concavity in each side, is shown in Fig. 18. It was found among the covering boulders of the grave of an adult, No. 42(4), in the sand at the western edge of the Columbia River about twelve miles above the head of Priest Rapids. The mortar shown in Fig. 19, is hollowed in the top of a symmetrical, nearly circular pebble and has a convex base. It was found on the Yakima Reservation near Union Gap and is in the collection of Mr. Janeck.[82] This reminds us of a similar mortar found in the Thompson River region,[83] but such simple mortars made from pebbles are rarely found in the Nez Perce region to the east.[84] The mortar shown in Fig. 20 also from the same place and in the same collection has a nearly flat base and three encircling grooves.[85] These grooves find their counterpart in four encircling incisions on the little mortar found in the Thompson River region.[86] [82] Museum negative no. 44455. 2-4.

From the Yakima Reservation near Union Gap. 1/2 nat. size. (Drawn from photograph 44455, 2-4. Original in the collection of Mr. Janeck.)] The specimen shown in Fig. 116, which may be considered as a dish rather than a mortar, was seen in the collection of Mrs. Hinman who obtained it from Priest Rapids. It is apparently of sandstone, 150 mm. in diameter, 50 mm. high, the upper part being 38 mm. high and of disk shape with slightly bulging sides which are decorated with incised lines,[87] the lower part being also roughly disk shaped 64 mm. by 76 mm. in diameter by about 12 mm. high with slightly convex bottom and edges curved out to the base of the upper part. There is a disk shaped dish in the top 100 mm. in diameter by 12 mm. in depth.[88] [87] See p. 125. [88] Museum negative no. 44537. 9-3.
