In some quarters a similar test is known as the “refraction” of the lac. NoTEs.-It will be noted that there are three depressions in the lower part of the glass extraction thimble to hold the cartridge above the bottom. This is very necessary for the reason that during the early part of the extraction a very free flow must be maintained to prevent the blocking of the syphon with the wax, which though readily soluble in hot alcohol is with difficultly soluble in cold. The object in filling the cartridge with cold alcohol before starting the extraction proper is to allow the resin and some of the wax to dissolve a t a low temperature. If the higher temperature of the boiling alcohol were immediately applied it would fuse the resin into a lump and render the extraction difficult. The first few drops of distilled alcohol which fall into the cartridge will cause the extract to syphon over, thus eliminating the bulk of the resin a t the start. If the extraction is continued much longer than the hour limit set above, substances other than shellac which are present will slowly dissolve though their complete extraction may require days. The total amount of alcohol is not important, but it should be noted that for convenience the alcohol should be of a depth in the flask u-hich will not quite reach the tip of the syphon tube The apparatu’s shown in the drawing may be obtained from Eimer & Amend, New York.

PRODUCTION O F CAMPHOR IIB JAPAN Consul General Thomas Sammons, of Yokohama, reports that Japanese statistical authorities at Tokyo place the production of camphor in Japan, including Formosa, a t 6,600,000 pounds. Assuming that the world’s production of camphor amounts to 12,000,000 pounds, Japan is credited with producing over one-half of the world’s supply. Formosa is represented by 4,600,000 pounds, and Shikoku and Kyushu by Z,OOO,OOO pounds. I t is predicted that the policy of the Japanese Government camphor monopoly may result in the stimulation of thc artificial camphor industry, the current price being $36.50 per catty of 133 pounds for class B coarse camphor. The Tokyo authorities place the Chinese camphor production at 1,300,000 pounds, and consider the industry in China t o be in its infancy. They believe that by forest protection in China the industry could be made very profitable and the output increased. They also indicate that an active rival of the Japanese camphor industry may result from the development of the camphor afforestation in Borneo and Sumatra, where foreigners are extensively interested. However, in most instances the camphor trees in Borneo and Sumatra will not be ready for use for a number of years. ~~
MINERAL PRODUCTION O F CANADA The Preliminary Report of the Canadian Department of Mines furnishes preliminary figures (subject to revision) of the total value of the mineral production in Canada during 1912 as $133,12 7,489. Compared with 1911, this production shows an increase of $29,906,495, or nearly 29 per cent. A substantial rise i n price for most metals during the year had an important

CEMENT PRODUCTION A N D CONSUMPTION
The data of production of cement are of particular interest in view of the widespread demand for this material. Statistically the important features of the industry during 1912were increases of over 26 per cent in the Canadian output, 116 per cent in imports, and 34 per cent in the total consumption. Canadian mills supplied 83. z per cent of the consumption as against 90 per cent in 1911. The total quantity of Portland cement, including slag cement and natural Portland, made in 1912, was 7,169,184 barrels. The quantity of Canadian cement sold or used was 7,120,787 barrels, valued a t the mills a t $9,083,216, or a n average of $ I . z j per barrel. The total imports of cement were 5,020,446 hundredweight, equivalent to I ,434,413 barrels of 350 pounds each, and valued at $1,969,529,or an average of $I . 3 7 per barrel.
