as the Milton Parks. Across it a dyke was built (see dotted 
line, Pl. II., Fig. 3), which divides this field and the Dunrod 
Kirkyard from a like field on the east, which also contains a 
goodly number of sculptured rocks. In honour of its discoverer, 
I have named this Thompson’s Stone. The turf being worn off 
by cattle, there is exposed to view a surface of some fifteen 
square feet, very distinctly carved, asshown in Pl. IT., Fig. 3. It 
contains five plain cups, three cups surrounded each by a single 
‘ring, two cups surrounded by concentric rings, and two cups 
with rings and flexed lines ; in addition to which there are two 
oblong cavities. The diameter of the largest ring is eight inches, 
and of its central cup two inches, the others in proportion. The 
depth of the cups is barely half-an-inch, while the rings scarcely 
reach that. The rock has been much disintegrated, and no 
doubt once bore more cups and rings. Owing to its exposure, 
the weather has worn down its surface very considerably. 
To the east of this dyke, at some 60 yards away N.E,, is a 
similar rock, sloping N.E., which contains numerous sculptures, 
but all (with one exception) of the same types as those just 
described. The exception referred to is a group of five concentric 
circles with a very broad channel beginning at the third ring— 
very similar, therefore, to the largest group on the Auchenlarie 
slab (Pl. II., Fig. 1), and to the larger group on the rock at 
Clachandolly (Pl. VI.) The surface of this rock at Milton is 
very closely covered with rings, cups, and grooves, but as the 
rock has also been severely weathered, it is extremely difficult to 
say what may be artificial groovings and what natural cracks and 
narrow fissures, if indeed the one may not be the cause of the 
other. There are at least 15 cups and 20 rings on this stone, 
besides oblongs, the largest ring being almost 12 inches in 
diameter and the smallest about 34 inches. The oblongs on 
these Dunrod rocks are all small—not more than 24 in. by 114 in. or 
thereabouts. In this East Milton field there are a great many cups 
and rings of the same types as those just described. TI shall, 
therefore, note only such as have marked peculiarities. One such 
is shown in Pl. II., Fig. 2, where we find a large cup, larger than 
the central one, lying between the two outer rings of the group 
of four concentric circles—the greatest diameter being 10 inches, 
the outside cup being 2 inches wide. A groove connects the 
third of these rings with the ring of a second group about 10 
inches distant, and another single cup and ring are carved about 
four inches to its northerly side.
