One of flint, 5 inches long, from the neighbourbood of Beauvais (Oise), is in the Blackmore Museum. The same form has also been found in Portugal[1] and Algeria.[2]
A stone implement,[3] "a square chisel at one end and a gouge at the other," was found in one of the Gibraltar caves.
In North America,[4] including Canada and Newfoundland, gouges formed of other varieties of stone than flint are by no means uncommon, and among the Caribs of Barbados, where stone was not to be procured, we find gouge-like instruments formed from the columella of the large Strombus gigas. On the western coast of North America, mussel-shell adzes are still preferred by the Ahts[5] to the best English chisels, for canoe-making purposes.
Some narrow bastard gouges, almost semicircular on one face and flat transversely on the other, but not hollowed, have been found in the Swiss Lake-settlements. I have one of diorite, 534 inches long and 1 inch broad, from Sipplingen. The butt is roughened as if for insertion in a socket. A similar form is found in Germany. I have a specimen 912 inches long found in the neighbourhood of Mainz.
A bastard form of gouge, mounted as an adze, is in use in the Solomon Islands. One tied to its haft with rattan is in the Christy Collection.
