“The Man's Knife among the North American Indians — a study 
in the collections of the U. S. National Museum " — is a paper of eight- 
een pages by Professor O. T. Mason, and supplements that pub- 
lished in 1890 upon * The Ulu, or Woman's Knife.” The knives 
used by the men of the American race may be classified in three 
groups : the curved knife, straight blade, and a metal blade per- 
forming the function of a burin. With the introduction of iron the 
arts of the peoples using the curved knife were greatly improved. 
This is especially noticeable in the Northwest, where the carving 
of the older period with beaver-tooth or shark-tooth knives was of 
an inferior kind. 
* Arrow Points, Spearheads, and Knives of Prehistoric Times," a 
profusely illustrated paper of 188 pages, by Dr. Thomas Wilson, 
. concludes the volume. After dealing with the spears and harpoons 
of the paleolithic period, the origin, invention, and evolution of the 
bow and arrow, and superstitions concerning arrow points and other 
prehistoric stones in the opening chapters, Dr. Wilson describes the 
flint mines and quarries in western Europe and in the United States. 
From the quarry at Spiennes, Belgium, flint implements have been 
distributed over southern Belgium and northeastern France. Fifteen 
neolithic stations, extending over forty-five communes, have been 
found, all in direct relation with Spiennes, creating a network of 
roads which have remained in use until modern times. 
At Grand Pressigny the débris of the flint quarries still en- 
cumbers the ground for miles around. It is of a peculiar yellow or 
waxen color, and hence can be easily traced through northern, 
western, and central France, and even into some of the lake dwell- 
ings of Switzerland. At Mur-de-Barrez, France, shafts and galleries 
were dug in the search for the best flint. Perhaps the best known 
quarry is that at Brandon, England, which covers twenty acres and 
consists of shafts or pits partly filled, dispersed over the surface, 
sometimes so close together as to break into one another. 
The best known flint quarry in the United States is at Flint 
Ridge, Licking County, Ohio. The ridge is about eight miles in 
length east and west, and two and one-half north and, south. The 
flint is not in nodules, but in a continuous stratum from three or 
four to seven feet thick. The worked area is about two miles square 
and is covered with soil to a depth of four to ten feet. 
The composition and structure of the materials employed in the 
manufacture of arrow points and spearheads are illustrated in repro-
