change, the effect in their case being usually confined to greatly 
increased hardness and compactness, or to the development in 
the mass of mica scales and metallic sulphurets ; but among the 
finer beds, now mica schists, the alteration is often much more 
extreme, the mica being not only far more conspicuous, but 
accompanied, often over large araas, by multitudes of staurolites 
and small garnets, as well as andalusites. The staurolites are 
often quite perfect and readily separable from the matrix, but 
the andalusites are rarely well formed or differentiated, shading 
into the associated rock, while they are themselves indefinitely 
penetrated by mica, garnet, and staurolite crystals. The best 
localities for the collection of staurolites are the vicinity of 
Jordan Falls, and the west side of Shelburne Harbor, in the 
village of Carleton, while both these and andalusites may be 
found in large numbers about Baccaro, on St. Anne’s Point, in 
Pubnico, and about Brazil Lake and Lake Annis in Yarmouth 
County. The garnets observed upon the coast, though numerous 
and usually quite clear, were all small, while those of the interior, 
along the borders of the granite, while considerably larger, were 
generally dull. A somewhat remarkable exampie of this latter 
class is to be seen in the fields half a mile east of Brazil Station 
on the Dominion Atlantic R. R. in Yarmouth, the schistose rock 
having its surface thickly covered with projecting crystals of this 
mineral from the size of a pea up to a diameter of an inch or 
more. Rocks of very similar character occur about the shores 
of Lake George, and again upon the coast at Chegoggin Point. 
Near an old quartz mill in this vicinity is an 18 foot belt of 
garnetiferous schist, having cross veins of pure garnets mingled 
with hornblende and menacoanite. Along the same belt of 
metamorphic strata (between Yarmouth Harbor and Lake 
Wentworth) the rocks frequently contain scattered sheafs of 
hornblende, and in places become a nearly pure hornblende rock, 
Quite a different type of metamorphism is to be found along 
the northern side of the great central granite tract in Digby and 
Annapolis Counties. Here the stratified rocks which adjoin the 
granite are of much more recent origin than those described
