4th, There is another group of stones , five or six in number, on 
Hatton Hill, about 500 yards to the east of the hill top, and about 
20 feet below its level. Each of these stones is on average about 
a cubic yard in solid content, and weighs about two tons. 
Hatton Hill is at its top about 900 feet above the sea. The farm 
of G-lenballoch, on which most of the other stones are, is about 750 
feet above the sea. 
To revert now to the stone first mentioned, the annexed wood- 
cut will give an idea of its shape. The cups or cavities on its 
sides — which, however, are not well shown on the diagram — are 
from 2 to 3 inches in diameter, and from half an inch to one inch 
deep. The grooves are about half an inch deep and about half 
an inch wide. 
The cup-shaped cavities were first noticed about fourteen or 
fifteen years ago, by the Eev. Mr Herdman, and were shown by him 
to Dr Wise, a well-known archaeologist. At that time the part of 
the stone above the surface of the ground measured about 9£ feet
