IX RELATION TO MINING POLICY. WOODMAN. 167 



attempt to frame an exploration policy upon a supposed period- 

 icity of situation of the domes is likely to end in failure. 



In rebuttal, it must be said that we may not be acquainted 

 with all the domes existing upon the various folds. This is 

 undoubtedly true ; yet it but emphasizes the inability of dis- 

 tribution to contribute prophetically to our knowledge. On 

 the other hand, it enforces one aspect of the case which should 

 appeal to moneyed men interested in the problem of developing 

 our mineral industries. All the main anticlinal axes have been 

 (juite accurately mapped for the eastern half of the province by 

 Mr. Faribault, and the sheets for the most part published. 

 While small local folds may become known in the future, as the 

 second one at Salmon River was discovered after operations at 

 tlie Duff'erin mine had proceeded far enough ; and while some 

 of these may prove economically important, yet it is improbable 

 that there are many arches unnoted by Mr. Faribault's careful 

 traverses. But one or two cases of gold-bearing bedded veins 

 are so far known to exist in the troug'i of a syncbne ; and from 

 the mechanics of the mountain building and attendant vein 

 phenomena, it is not to be expected that such deposits will 

 occur along the synclinal axes to any extent. So that, while 

 our evidence upon this important point is either circumstantial 

 or negative, it is probably safe to neglect these folds entirely 

 in exploring for new deposits. Moreover, many of the synclinal 

 axes outcrop in the overlying black slates, and therefore in 

 rocks in which abundant gold-bearing leads would not be sought. 



Again, while a few instances of isolated bedded veins are 

 known in the transverse interval between an anticline and a 

 syncline, and at a considerable distance from the axis of the 

 former, they are rare ; and they are not to be looked for to any 

 considerable extent. It is along and close to the anticlinal axes 

 that w^e know the deposits now worked, and that we should 

 expect to find new ones ; and further, it has been heretofore 

 upon the bulged or domed parts that search has been made.
