44 TORRS WARREN. 
which it is difficult to conceive a use. (See Zrans. Geol. Soc., 
Glasgow, Vol. VI., p. 185.) 
Hammer stones are frequently got, the favourite material having 
been well-shaped oval pebbles of quartzite, as combining in itself 
the useful properties of great hardness and toughness ; but quartz, 
granite, Ailsa rock, greywacke in its varieties, greenstone, etc., 
have been used. Some of these hammers have been trimmed till 
a sharp ridge, generally at the end or ends of a pebble, has been 
formed, and as this ridge (which sometimes passes obliquely over 
the end or even right across) seldom has a chip broken from it, it 
shows that the ridge must have been of prime importance for 
certain kinds of work, and also how carefully the hammers had 
been used. Other hammers had been sorely battered at the ends, 
and some on all the sides.. The finger and thumb hammers have 
a neatly-made hole on each side, generally of a flat, sometimes 
roundish, pebble. In fact, pebbles of any shape, from the oval- 
flat-compressed to the nearly globular, have been made use of as 
hammers. It is quite common to see stones very suitable for 
using as hammers, and yet they show no marks of usage: they 
were probably kept in stock, and are frequently got where flint 
chips and iron slag abound. 
Sling stones are scarce, but suitable pebbles would, of course, 
be oftenest used as sling stones; but I refer to stones—often flint 
—which had been trimmed. 
A few perforated hammer axes have been found. 
All kinds of stones have been used as anvils, which are easily 
recognised by their battered surfaces, and were probably always 
used when flakes of flint were being struck off. 
Urns of different shapes, and ornamented in a variety of 
patterns, have been obtained from the Torrs, and probably belong 
for the most part to the ‘Bronze Age,” bronze articles having 
been found in some of them. I was informed by one of the 
trappers that he had seen an urn with the bones in it reduced to 
particles about the size of barley, and he suggested that they were 
the remains of the cremated bones of a child. Those who are in 
the habit of searching for “antiques” soon learn to know the 
spots where urns may be lying. When the wind blows an old 
surface bare this surface is always of a dark colour, but if there is 
a gray patch on it an urn will probably be found in such a spot.
