22 Recent Excavations at Stonehenge. 
had been filled in against the side of the stone, doubtless to afford 
a more substantial support for it than mere earth or rubble. 
That this filling was not of modern date is proved by the in- 
crustation on many of the pieces, by which, in fact, some were 
cemented together. 
The Stone Implements.——More than a hundred stone implements 
were found, and the greater number occurred in the stratum of 
chalk rubble which either directly overlaid or was on a level with 
the bed rock. 
They may all be arranged in four principal classes, between 
which, however, there is not in all cases a very distinct line of 
demarkation. Even in the same class, especially in Classes I. and 
IIL, some examples present wide differences from others, but on 
careful examination many intermediate links will be found by 
which they are connected. 
These positions, as we have already seen, are projected on the 
plan (Fig. 2) and into a section of each excavation. 
Crass I.—Axes roughly chipped and of rude forms, but having 
well-defined, more or less sharp cutting edges. 
This class may be conveniently divided into two sub-classes, A 
and B, the implements in the former being characterised by a much 
greater length in proportion to their breadth than those in the 
latter. 
Crass II.—Hammerstones, with more or less well-chipped sharp 
curved edges. Most may be correctly termed hammer-axes. They 
are chipped to an edge at one end, but at the other are broad and 
thick, and in many examples terminated there by a more or less 
flat surface. In some the natural coating of the flint is left un- 
touched at the thick end. 
Crass I1]—Hammerstones, more or less rounded. Flint. Some 
specimens appear to have once had distinct working edges, but 
they are now much blunted and battered by use. 
All the implements in the above classes (with the exception
