at least to a noticeable extent. But a still more peculiar form is that 

 seen at the Megantic mine in Colerain •, where the serpentine wall for 

 the distance of several feet is laced with minute veins of not more than 

 a twentieth of an inch in thickness, and presents the appearance, on 

 fresh surfaces, of a rock regularly and evenly striped with greyish white 

 I faint. The same mode of occurrence of small veins is seen at Kins 

 Bros.' mine in Ireland, and at Bellmina, and occasionally some of 

 these smaller veins there come together and form one of workable size. 

 This peculiarity is also conspicuous in the serpentine asbestus deposits 

 of Templeton and the Gatineau district, although the character and age 

 of the containing rocks are entirely distinct from those of the eastern 

 area. In this latter place the small veins of asbestus have a thickness 

 generally of an eighth to a fourth of an inch, with partings of lio-ht 

 greyish serpentine of about the same thickness. These occur through- 

 out a space sometimes of a foot or even possibly more, and enclose 

 roughly lenticular masses of limestone, which are often of large size. 

 Sometimes several of these detached veins coalesce and produce a lar^e 

 vein having a thickness of two inches of wonderfully clear fibre, which 

 continues for a short distance and then splits up again. The same 

 peculiarity is seen in the lower part of the large vein at the Broi ghton 

 mine in eastern (Quebec, where the hanging wall is soapstone. 



While, therefore, indications of asbestus or chrysotile may be 

 found at most places where serpentine rocks occur, it is, I think, very 

 clearly established by the work of prospectors, as well as by that of the 

 staH'of the Geological Survey, that very many areas do not contain nor 

 are likely ever to produce, asbestus in workable quantities ; and while 

 the greatly enhanced price of the mineral renders operative, areas 

 which a few years ago could only be worked at a loss, it must be borne 

 in mind that the great profit is made in the output of first-class mate- 

 rial, rather than in third-rate asbestus. To any persons, therefore 

 contemplating investment in such mining areas, it is plain that the 

 hist thing to be attended to is a careful examination of the property 

 by one not personally interested in the matter, and one, further, 

 who has a good knowledge of the different kinds of serpentine, 

 as well as of the conditions which should govern the occurrence of 

 asbestus in sufficient quantity to repay the money invested. Unfortu-. "f» (1 i~ >s >v
