ON THE SHELL-BEARING DEPOSITS IN KINTYRE. 393 
Stones mostly water-worn, some angular ; no striations observed. This 
shows a much higher percentage of mud, and a smaller percentage of 
gravel and sand than the above, which may be accounted for by much of 
the fine mud and sand being washed away from the overlying weathered 
surface clay, and a portion of the stones slipping down from the higher 
boulder-clay and mixing with the surface shelly clay. 
Shallow Bores sunk in 1895 to test the extension of the Shelly Clay 
Eastwards. 
(c) Shallow Bore, No. 1.—8 feet from surface ; 22 yards east of main - 
section ; the clay consisted of—mud, 59 per cent. ; sand, 12 per cent. ; 
gravel, 29 per cent. 
Stones mostly water-worn, no striations observed, 2 organisms, might 
be Deflugi. No other animal remains. 
(d) Shallow Bore, No. 2.—10 feet 9 inches from the surface ; 44 yards 
east of main section ; the clay consisted of—mud, 54,per cent. ; sand, 18 
per cent. ; gravel, 28 per cent. 
Stones angular and water-worn in about equal proportions ; no animal 
remains or striation observed. 
(e) Shallow Bore, No. 3.—9 feet 5 inches from surface ; 66 yards east 
of main section ; the clay consisted of—mud, 76 per cent. ; sand, 6 per 
cent. ; gravel, 18 per cent. 
Stones mostly angular and water-worn ; no striation or animal re- 
mains observed ; one Deflugi sp.? The ‘floats’ were full of vegetable 
fragments that had much of the appearance of being waterlogged. 
(f) From the extreme eastern exposure of shelly clay 88 yards east 
of main section ; 12 feet 10 inches above level of stream ; 3 lbs. of clay 
consisted of—fine mud, 96 per cent. ; coarse sand, 3 per cent. ; gravel, 
1 per cent. 
Stones mostly angular, the others water-worn, no striation detected, 
a few small fragments of shells. Ostracoda and Foraminifera were 
present in small numbers. 
(9) Gravel at bottom of Shelly Clay.—From bottom of trench cut into 
main section 11 feet from surface and 2 inches below level of stream, 14 
feet back from stream. This bed of coarse sand and gravel was 3 feet 
10 inches thick, very hard ; esaee not reached. The clay consisted of— 
mud, 28 per cent. ; ; gravel, 7 72 per cent.
