YO IN THE ACADIAN LAND. 



a ton, over all the Province of Nova Scotia. Here 

 on these Molega ores it is about twenty dollars, 

 and since it is too fine to save in a stamp-mill 

 it is lost, and can only be saved by a chemical 

 process. This fine gold was entrapped in these 

 base-metal crystals when they were formed from 

 solutions that contained the dissolved silica and 

 all its associates in the vein. 



It will now be in order to say something about 

 the origin of these quartz veins, that prove so 

 useful to mankind that without them we would 

 not be able to have gold and silver, and copper 

 and tin, and antimony and zinc, and many other 

 metals. Iron ore also occurs very largely in 

 veins. The metals might have existed in the 

 same quantities, and yet be either dissolved in 

 water or scattered in minute quantities through 

 vast strata of rocks. In just those conditions they 

 once existed, and the ocean is the great storehouse 

 of precious metals held in solution, and all the 

 veins in the world contain but a very small per- 

 centage of what is distributed through the rocky 

 crust. I know of no other natural feature that 

 seems so clearly to indicate a preparation for 

 the human race as these storehouses of metals 

 these hoards of needed material brought to- 

 gether by the subtle action of chemical laws 

 working with physical conditions of the crust
