310 STRATIGRAPHICAL GEOLOGY. 



reaching- the southern end of the basin. The junction there is not regu- 

 lar, but through a fault. The irregularities on the eastern side may be 

 due to the elevation of a considerable band of Lyman schists, starting 

 near the line and extending north-easterly towards the Dodge gold mine. 



A few isolated patches of this conglomerate occur south of Aldrich's 

 in Lyman. One has been known as the gold mine of Tute & Co., at 

 U — 7. The ledge is one hundred feet long, running north and south. 

 There is a smaller patch of it at O — 7, with the strike N. 80^ W. The 

 relations of these isolated patches to the great ranges have not been con- 

 jectured. 



The phenomena of the occurrence of auriferous conglomerate along 

 the eastern range of the Lyman group are similar to those just enumer- 

 ated upon the western belt. The most northerly fragments occur from 

 half to a quarter of a mile south-west from Mill brook in Lisbon, on the 

 road from a saw-mill to C. E. Woolson's (county map). These ledges 

 run N. 63° E., dipping 75° N. 27° W., and are fifty feet wide. Like 

 the conglomerate mass on the hill east of the New England Reduction 

 Works mine, it is flanked on the east by Helderberg limestone, though 

 in very limited quantity. The next conglomerate ledge occurs in Lyman, 

 nearly two miles to the south-west, and reaches from near J — 2 to H — 3, 

 a distance of iioo feet. The dip is 75° south-easterly. This fragment 

 is often one hundred feet wide, flanked by Lyman schist. Its continua- 

 tion is 1200 feet further in the same direction, with a slight easterly dip. 

 The fragment is straight for about five hundred feet, when it is bent 

 southerly at a right angle, and disappears. Large boulders of it may 

 show its continuance for over a hundred feet; and there are a great 

 many pieces of it for 1000 feet between B and C — 5, which are sugges- 

 tive of the occurrence of ledges there. Two fragments, near A — 5 on 

 the town line, may belong to this band, each two hundred feet long, and 

 the nearest one three hundred feet from the eastern belt. 



The eastern belt is continuous from a swamp midway between E and 

 F — 2 to a point one hundred and fifty feet into Bath, below A — 4, 2850 

 feet in length. At the north-western end it runs east and north, and at 

 the Bath terminus its course is from N. 30°-40° E. It is usually seventy 

 feet wide. At the Gordon mine, between C — 4 and D — 3, the dip is 60° 

 S. 32° E. Five hundred feet farther north the dip is in the opposite
