_Oar._--Portion of what appeared to have been a large oar was found on the crannog, but, from its fragmentary state, we could only ascertain that the blade was 9 inches broad and 1-1/4 inch thick, and that the handle measured 5 inches in circumference. DESCRIPTION OF RELICS. The relics are here grouped under several heads, in accordance with the method of classification adopted in my previous monographs, and, to save repetition, I may explain, that (when not otherwise stated) they may be considered to have been found either _in situ_ in the refuse-heap, or among its stuff after it was wheeled out and subsequently examined. I. OBJECTS MADE OF STONE. [Illustration: Fig. 192.--Stone Polisher (2/3).] _Hammer-Stones_, _Polishers_, _etc._--Only two or three typical hammer-stones have to be recorded as found on this crannog. One is an elongated flat pebble, and shows the usual markings at both ends, another only at one extremity, and a third is somewhat circular, with the markings on the flat surface alone. Under the category of polishers are included seven or eight highly polished water-worn pebbles, varying much in size and shape. Two, shaped like pebbles, are 7 inches long, and have slight pounding marks at both extremities (Fig. 192). Three are flat and oblong, and measure from 2-1/2 to 4 inches. _Sling-Stones_, _etc._--Like the hammer-stones, these objects are comparatively rare, only a few having been added to the collection. _Whetstones_, _Grindstones_, _etc._--Of these objects the following are noteworthy:-- 1. A large flat implement, made of bluish claystone, with a smooth polished surface, and having a hole roughly cut out of one end. It measures 12 inches long, 4 broad, and 1-1/2 inch thick (Fig. 193). [Illustration: Fig. 193.--(?) Whetstone (1/3).] 2. One or two ordinary whetstones a few inches long, and from 1 to 2 inches broad. 3. An oblong block of sandstone, containing two smooth cavities, probably used for polishing small objects such as jet rings. One of the cavities is a hollowed circle 2-1/2 inches in diameter, and half an inch deep; the other is a groove 3 inches long, half an inch wide, and the same in depth (Fig. 194). 4. Two fragments of a circular grindstone, made of fine red sandstone. One of the portions shows a few inches of the striated circumference as well as a small segment of the central hole. The diameter of the stone when whole would be about 15 inches. [Illustration: Fig. 194.--Block of Sandstone (1/4).] 5. Two large irregularly-shaped masses of whitish sandstone, each containing a smooth cavity shaped like a trowel or botanical spud, having the sides curled up. One of these curiously-shaped cavities measures 10 by 8 inches. Its greatest depth, which is at the base and in the line of the shortest diameter, is 3 inches. The other is precisely similar in shape, but of smaller dimensions. The latter stone has friction-marks on another of its sides.
