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 belt of rock is nearly three-(iiiartei's of a mile and the cornndnm is 
found throughout the whole distance. Tt occurs in crystals of an 
ahnost uniform light-gray to white color that are usually about half 
an inch in diameter, the largest ones being 1| inches long. 
AUSTRALIA. 
In the central part of Queensland " there is an area of about 50 
square miles where sapphires are found more or less abnndantl}^ in 
the old gravel and alluvial deposits. This was known as the Anakie 
sapphire fields, which are reached by the Central Railway, their sta- 
tion being Anakie, which is 20 miles from Emerald and 192 miles 
west of Rockhampton. The principal gravel deposits are along the 
banks of the Washpool, Retreat, Policeman, Serpentine, Tomahawk, 
nnd Central creeks. Sapphires have rarely been found in the streams 
themselves. Very few blue sapphires are found in these deposits, 
and the prevailing colors are various shades of green and yellow, the 
green stones being similar to those obtained from the Missouri Ri^Tr 
l)ars, described on page 109. Some of the Queensland stones are of 
bright green and yellow colors, making very handsome gems. The 
sapphires are often marked with hexagonal outlines, striations, etched 
figures similar to those described in the North Carolina rul)ies and 
Montana sapphires on pages 103 and 114. 
The source of these sapphires is very probably the l)asaltic dikes 
which have been observed cutting the granitic rocks and in which 
some sapphires have l)een found. 
INDIA. 
The cornndnm deposits of India have been described by T. H. Hol- 
land.'^ He gives the Pararapatti area in the Salem district of the 
province of Upper Burma as one of the most promising for the min- 
ing of cornndnm for abrasive purposes. He describes the corundum 
as occurring in a matrix of deep flesh-colored feldspar Avhich is in 
bands or lenticular masses, and has associated with it often a consid- 
erable 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 horn- 
blende, and in parts has a gneissoid structure, and these portions
