pratt.] CORUNDUM LOCALITIES. 89 
here occurs in the normal syenite. A corundum mill has been erected 
that will have a capacity of 5 tons of cleaned corundum a day. 
This companj^ also owns corundum deposits on the York River 
in Carlow and Dungannon townships, Hastings County. At these 
localities the corundum occurs in a nepheline-syenite, and while it is 
apparent^ of superior quality to that found in Raglan Township, the 
percentage of corundum is not as high. No mining is being done by 
the company at these York River localities. 
The manager of the company is Mr. Ii. A. C. Craig, of Toronto, 
Canada. 
Miller 1 has described specimens of corundum from Methuen Town- 
ship, Peterborough County, that are entirely inclosed by mica. He 
says: "The corundum is often not observed in the mica until the 
latter is broken open, when it is round forming the center or core of 
the mass. The rounded surfaces of the corundum and oilier charac- 
terises leads to the belief* thai the masses of light-colored mica are 
secondary products after corundum." This very closely resembles 
specimens of corundum surrounded bymuscovite mica thai have been 
found at the Presley mine in Haywood County, X. C. (see p. S5), 
in which the muscovite is undoubtedly a secondary product after the 
corundum. 
In the township of South Sherbrooke, Lanark County, 2 corundum 
has been found in a rock 1 hal is made up ol* a basic plagioclase feldspar 
and green hornblende, ami has been called anorthosite by Miller. It 
is more basic in character than the typical varieties of this rock that 
have been described from other parts of Canada. The width of the 
bell of rock is nearly three-quarters of a mile and the corundum is 
found throughout the whole distance. It occurs in crystals of an 
almost uniform Light-gray to white color thai are usually about half 
an inch in diameter, the largesl ones being one and a quarter inches 
long. 
INDIA. 
The corundum deposits of India have been described by T. II. Hol- 
land. 3 He gives the Pararapatti area in the Salem district of the 
province of Upper Burma as one of the most promising for the mining 
of corundum for abrasive purposes. He describes the corundum as 
occuring in a matrix of deep flesh-colored feldspar which is in bands 
or lenticular masses, and has associated with it often a considerable 
proportion of sillimanite, rutile, opaque black and green spinel, and 
biotite. These masses, where they have been actually seen in the 
rock, are sometimes as much as 15 feet long and 8 feet in diameter. 
The feldspar rock is composed essentially of anorthite and hornblende,
