18 JADE stantial houses, ornamental carvings, to- tem-poles, and canoes dug out of giant cedars—wonders of marine architecture. Before the introduction of iron, all of this work was executed with stone tools, of which the jade celt was the most impor- tant. Among the Tlingit, the value of a jade adze-blade two or three inches in length was from one to three slaves. When its owner used it, his wife should refrain from all frivolity, as any unbecoming con- duct on her part might cause the blade to break. That some of these coast people worked jade is proved by the finding of cut bowlders and sandstone tools about the mouth of the Fraser and along the eastern shore of Vancouver island; but farther north, while celts have been found everywhere, few natural or worked bowlders have been discovered, and, so far as known, no cutting tools. Dr Newcombe, of Victoria, in- forms the writer that he possesses a cut bowlder of jade that was found at Fort Rupert while digging at an old house-site.
