The perforation is much enlarged at the ends, giving cup-like cavities. The walls are thin near the ends and quite thick near the middle, the passage being hardly more than one-quarter of an inch in diameter. The markings on the inside indicate that the excavation has been made by a gouging process, rather than by the use of a rotary perforator.

62776. A boat-shaped ceremonial stone of banded slate, 3 inches long, 1 inch wide, and 1 inch deep. From the side the outline is triangular, the two lines of the keel forming almost a right angle. From the top the outline is a long, pointed oval, as seen in the illustration, [Fig. 131].

The trough-shaped excavation is more rounded in outline, and is three-fourths of an inch in depth. Perforations have been made near the ends of this trough; these seem to be somewhat abraded on the outside by a cord of suspension or attachment which has passed between them along a groove in the apex or angle of the keel.
