perial Institute, London, and was pronounced by experts to be of ex- 
ceptionally high value for electrical purposes. Molybdenite from Que 
bee and Ontario was tested in the laboratory of McGill university 
and samples of auriferous black sands from the Atlin district were 
also examined. These samples varied from 0.5 oz. gold per ton to 
5.985 oz. gold per ton. Mention is made of the discovery of anthracite 
coal in the region about the headwaters of the Sheena and Slikinc 
rivers. It is estimated there are 22,000,000,000 tons of possibly work- 
able coal in the Crow's Nest Pass coal fields. Coal has also been 
found in the Klondike region but so far possesses only a medium eco- 
nomic value. 
Reference is made to the collection sent to the Paris exposition. 
This collection weighed about 70 tons, and comprised over 1,200 sepa- 
rate exhibits and was much larger than any shown by Canada at any 
previous international exposition. The awards actually awarded to the 
Canadian mineral exhibits comprise six grand prizes, ten gold medals, 
eighteen silver medals, nine bronze medals and four honorable men- 
tions. 
The most important facts of economic value are contained in the 
descriptions of the following: The placer mines (estimated, to pro- 
duce over $16,000,000 this year), the lignite area and the White Horse 
copper deposits in the Yukon district, the Atlin and West Kootepay 
gold fields and the extensive coal area of the Crow's Nest pass, in 
British Columbia, the iron bearing rocks of the Michipicoten district 
including the Helen mine, which from definite measurements con- 
tains 26,000,000 tons of ore and possibly a much larger quantity : the 
alluvial gold deposits of New Brunswick, and the extensive and im- 
portant coal deposits of Springhill and Cape Breton in Nova Scotia. 
A large amount of work was done by all the field parties in mapping 
out the geological formations, and in making surveys and collecting 
facts about the regions traversed so that the report contains valuable 
information about the physiography and natural history of large areas 
in the older provinces as well as in outlying districts including Great 
Bear lake. 
The work done in chemistry and mineralogy, mineral statistics, petro- 
graphy, palaeontology and zoology, botany and mapping is fully set 
forth by the gentlemen in charge of these branches. w. j. w. 
Analysis of Emery from Virginia. By W. W. Miller. Jr. Am. Client. 
Jour., 22, 212-213. 
The emery occurs in a heavy ledge near Whittle's on the line of 
the Southern railroad in Pittsylvania county. It is described as a black, 
crystalline mass ; magnetic ; polar ; with specific gravity 4.205 ; and 
hardness, 8. The analysis shows: — alumina, 56.74; ferric oxide, i5-5o; 
ferrous oxide, 20.77; silica, 0.68; titanic oxide, 1.86; soda, 3.95. The 
ferrous oxide in excess of that required to form magnetite, is supposed 
to be present as hercynite, FeAl-04; and the soda is considered to take 
the place of the ferrous oxide in forming additional hercynite, thus 
greatly reducing the amount of alumina which can exist as corundum.
