as the Miltou Parks. Across it a dyke was built (see dotted 

 line, PI. 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 ofl" 

 by cattle, there is exposed to ^-iew a surface of some fifteen 

 square feet, very distinctly carved, as shown in PI. II., 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 wliich 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 

 deptli of tlie 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 (PI. II., Fig. 1), and to tlie larger group on the rock at 

 Clachandolly (PI. 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 lea.st 15 cups and 20 rings on this stone, 

 besides oblongs, the largest ring being almost 12 inches in 

 diameter and the smallest about 3^ inches. The oblongs on 

 these Dunrod rocks are all small— not more than 2i in. by 1 i°in. or 

 thereabouts. In this East Milton field there are a great many cups 

 and rings of the same types as those just described. I shall, 

 therefore, note only sucli as have marked peculiarities. One such 

 is shown in PI. 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 

 niches distant, and another single cup and ring are carved about 

 four inches to its northerly side.
