Small axe, with a groove round the body quite near the blunt end; basalt. 17. (40565). Axe, three and a half inches long. 18. (40566). Quite small, probably a hatchet, of firm basalt, grooved near the hammer end. 19. (40567).

Pick-shaped axe, grooved entirely around, with imperfect depressions which were in the water-worn boulder from which it was made; about six inches in length. 22. (40570). Boulder of sandstone with groove near the middle. 23. (40571). Flat basaltic boulder, grooved near the center, straight on the back, and tapering above and below the groove. 24. (40572). Small basaltic hammer and axe with groove near the large end. 25. (40573). Small grooved axe composed of hard sandstone; hammer end large, edge quite perfect. 26. (40574). Small boulder of basalt, ground to an edge at one end and rounded off at the other; doubly grooved. 27. (40575). Large basaltic stone considerably chipped off from pounding hard substances, grooved near the center, both ends quite blunt; probably used as a pounding stone. 28. (40576). Flat basaltic boulder, used as a pounder. 29. (40577). Basaltic hatchet grooved in the middle; quite rough. 30. (40578). Grooved axe of a very heavy, solid character, apparently designed more for mauling than cutting. 31. (40579). Large, heavy basaltic hammer and axe with groove around the body near the hammer end; about seven inches long. 32. (40580). Axe, grooved in the middle, upper or hammer end unusually long in proportion to the size. 33. (40581). Flat axe made from a water-worn boulder, oval in outline, both edges designed for cutting or splitting. Deep groove encircling the body, with protrusions above and below it to prevent the handle from slipping out; greenstone. 34. (40582). Hard, fine-grained sandstone axe wedge-shaped, without a groove. 35. (40583). Grooved axe with round body.
