GEOLOGY OF THE CONNECTICUT VALLEY DISTRICT. 303 



fore, that there is a range of Lyman rock from Partridge pond to the 

 Connecticut near the Upper Waterford bridge. 



There is an eastern range of the Lyman group similar, as respects 

 mineral composition, to that just described, requiring notice. It adjoins 

 the green schists extending into Lyman from Bath, thought to be subordi- 

 nate to the white schists. They are 2500 feet wide on the Lyman line, 

 including three narrow conglomerate belts. The following are such posi- 

 tions of the strata as have been determined in this area : 



283, dip 80° N. 82° W. 400 feet east of B— 3, and near road, dip 



280, dip 64° S. 57° E. 67 S. 57° E. 



At B — 5, dip N. 57° W. Close by conglomerate, 300 feet east of 



Half way to C — 5 the dip changes to 65° C — 4, dip 70° S. 57° E. 



S. 57° E., thus indicating the presence Dip beneath the conglomerate, on the 



of an anticlinal. other side, in a similar manner. 

 Near C — 3, vertical, strike north-easterly. 



Near the south end of the conglomerate, between E — 5 and F — 4, are disturbances. 

 The schists, six feet distant from the conglomerate dipping N. 42° W. 80°, and sepa- 

 rated probably by a fault, are inclined 70*^ south. 



At F— 3, dip N. 22° W. Between L and M— o, dip 75° N. 23° W. 



Same, 100 feet west of F — 2. Town line east of O — o, dip 55° N. 17° W. 



Between G — 2 and 3, dip irregularly N. Anticlinal about M — i, dipping 55° N. 2° 



32° W. W. and 65° S. 47° E. 



At H — 3, dip 65° N. 22° W. 100 feet north of N — o, dip 75° northerly. 



East of J— 2. dip 60° N. 12° W. 



There is dolomite near H — 2 dipping 75° northerly ; between E — 5 and 6, dipping 

 70° S. 57° E., extending east of the conglomerate from Bath line 1000 feet between 

 lines 3 and 4, dipping 85° N. 62° W., and probably on the west side of the same range. 

 This range also contains argillaceous schists and beds or veins of quartz similar to 

 those described as connected with the larger area. 



The clay slate covers up most of this range in Lisbon, as has been 

 explained upon page 283. There is also a fault north of Jason Titus's 

 house, which aids in accounting for the disappearance of the Lyman 

 group. Beyond the sandy plain it may be followed, accompanying the 

 conglomerate as far as the saw-mill upon Mill brook, but it is quite nar- 

 row. 



Auriferous Conglomerate. The last of the Huronian members to be 

 described is usually a quartz conglomerate, with pebbles half an inch in
