Discoidal stones, resembling those shown in the Blackmore 
Collection, are found in abundance in Chili, some of which 
may have been used for arming clubs. ** In the plains and 
upon the mountains," says Molina, are to be seen a great 
number of flat circular stones, of five or six inches in diameter, 
with a hole through the middle. These stones, which are 
either of granite or porphyry, have doubtless received this form 
by artificial means, and I am induced to believe that they were 
the clubs or maces of the ancient Chilians, and that the holes 
were perforated to receive the handles." 
No. 29 is a disc of felstone, found in Ohio, with a central 
depression upon the two surfaces ; these depressions have been 
made by pecking;" the tool-marks are plainly to be seen. 
This specimen resembles No. 30, Case A 26, which was found 
on the bank of the river Bann, Ireland. The sides of the Ameri- 
can disc are rather more straight than those of the Irish speci- 
men. No. 30 is a drilled object of trachyte, found in Missouri ; 
it is of the form usually called a *' net-sinker." Similar speci- 
mens, from Ireland, are shown in Case A 26. No. 31 is a 
spindle-whorl " of fine-grained trachyte, Ohio. No. 32 is a 
sandstone disc, found in Ohio, ornamented on the two surfaces 
with an incised cross, inscribed within a circle ; this object is 
probably rather modern. No. 33 is a piece of whetslate, which 
appears to have formed part of a whetstone, Ohio. No. 34 is 
a piece of whetslate, which illustrates the mode adopted in 
working the material ; it was sawn partly through from each 
side, and then fractured along the weakened line. No. 35 is of 
whetslate, marked upon its upper convex edge with twenty- 
eight notches. The length of this object is five inches and a 
half ; its greatest breadth is one inch and a half ; it was found 
in Ohio. 
A 49. 
The stone tubes, Nos. i to 4, are described at page 126. 
Nos. 5 to 12^' are drilled stone axes, probably used as 
weapons of parade ; the material is too soft for any useful pur- 
pose, and the haft-holes are so small that the handles would be 
very liable to break. No. 6 is from Massachusetts ; the other 
specimens are from Ohio. 
* Nos. 5 and 10 are of clay slate ; No. 6 of felspathic greenstone ; Nos. 7, 
8, 9, II, 12, of whetslate. The material of No. 10 closely approaches whet- 
slate.
