streams; but though these outcrops have been carefully prospected, 

 nothing more than small gash veins have been found. Further to the 

 north-east on the south side of the great dioritic mass called Moose 

 Mountain in GYanbourne, a small outcrop of serpentine, on the bank of 

 the Etchemin River, shows small veins of one quarter to possibly half 

 an inch of fibre, and this is the most northerly outcrop of asbestus-bear- 

 ing serpentine yet known in this belt. 



The most easterly area, viz., that of the Shickshocks, is largely 

 made up of serpentine, different in character from the rock of Thetford 

 which we may take as our typical locality ; the southwestern portion 

 being very hard and siliceous, in contact with black hornblende schists 

 on the north ; while the eastern or Mount Albert serpentine, which is 

 the principal area in this direction, is frequently banded with shades 

 of reddish brown and green. In these rocks only small veins of im- 

 perfect fibre have )et been found, and the generally hard and siliceous 

 charac.er of much of the rock is against the presence of large deposits 

 of the fibrous variety. In the most easterly exposui-e, on the Dart- 

 mouth, the serpentine is very much of the same nature as in the Shick- 

 shocks, associated with hornblende schists and containing small veins 

 of one-quarter inch fibre of but little economic value. 



It is easily seen, therefore, that the character of serpentine which 

 is leally asbestus-bearing to an extent which can be profitably worked,, 

 is confined to a comparatively limited area, and more particularly to 

 contain portions of the townships of Thetford, Ireland, Coleraine and 

 Wolfestown, in which localities successful mining operations have been 

 carried on for some years. But even in these favored districts there 

 are large portions of the serpentine belts which, in so far as yet proved, 

 have disclosed no asbestus in quantity to be economically available. 

 The rock carrying the merchantable asbestus is generally a greyish 

 weathering serpentine of some shade of green on fresh fracture, general- 

 ly a greyish green, in which are contained numerous small particles of 

 iron, both magnetic and chromic, more generally the former. Ser- 

 pentines that have a black, hard, chippy aspect do not apparently 

 promise well, nor does the rock which weathers a dirty reddish brown. 

 In the asbestus-bearing rock proper the veins of asbestus are seen with- 

 out any special arrangement, intersecting the mass of the rock
