mission of yellow fever, and sacrificed his life 

 to the cause of scientific research. 



Professor N. H. Alcock, professor of phys- 

 iology in McGill University and the author 

 of important contributions to this science, has 

 died at the age of forty-two years. 



Dr. Forbes Winslow, who founded the 

 British Hospital for Mental Disorders and 

 was the author of numerous works on insan- 

 ity, has died at the age of seventy years. 



Sir Jonathan Hutchinson, a prominent 

 London surgeon, died on June 23, aged fifty- 

 four years. 



The University of Montana Biological Sta- 

 tion will be open from June 17 until Sep- 

 tember 1, under the direction of Dr. Morton 

 J. Elrod, head of the department of biology. 

 The laboratory is located on the east shore of 

 Flathead Lake, at an altitude of 2,900 feet, in 

 a tract of 8Y acres of virgin forest donated by 

 congress. Two other tracts of 40 acres each 

 are on islands but a few miles distant. The 

 Mission range of mountains come quite ab- 

 ruptly to the lake at the station, rising to an 

 elevation nearby of 8,500 feet. A few miles 

 to the south the elevation is 10,000 feet. The 

 lake is 30 miles long and at the middle, where 

 the station is located, it is 19 miles wide. It 

 covers nearly 400 square miles, has a shore 

 line of almost 150 miles and is 300 feet deep. 

 Up the lake from near the station a fringe of 

 fruit ranches borders the lake. Dovsm the 

 lake and for many miles beyond, the country 

 is an unsettled forest. Eastward the unbroken 

 forest extends across range after range until 

 the plains country is reached beyond the main 

 divide. The station was established in 1899, 

 and has continued with an interruption of 

 two years. Its former location was at Big- 

 fork, where Swan Eiver enters the lake at the 

 upper end. Last year a building was erected. 

 This is a two-story brick structure, capable of 

 accommodating about 25 workers. The staff 

 and workers live in tents, and meals are pro- 

 vided at a mess table. The facilities for work 

 are extended to elementary and advanced stu- 

 dents and to investigators. Those attending 

 the station may take such work as they please 



within certain limits, and all the assistance 

 possible will be rendered them. The field 

 method is largely employed. Courses will be 

 offered in botany, zoology, ecology, physiog- 

 raphy, ornithology, entomology, photography 

 and plankton, besides the facilities offered for 

 research. 



According to an advance statement by 

 Ernest F. Burchard, of the United States Geo- 

 logical Survey, the total quantity of Portland, 

 natural and puzzolan cements produced in the 

 United States in 1912 was 83,351,191 barrels, 

 valued at $67,461,513, compared with 79,547,- 

 958 barrels, valued at $66,705,136, in 1911. 

 This represents an increase in quantity of 

 3,803,233 barrels, or 4.78 per cent., and in 

 value of $756,377, or 1.13 per cent. The dis- 

 tribution of the total production among the 

 three main classes of cement in 1912 is as fol- 

 lows: Portland, 82,438,096 barrels, valued at 

 $67,016,928; natural, 821,231 barrels, valued 

 at $367,222; puzzolan, 91,864 barrels, valued 

 at $77,363. The total production of Portland 

 cement in the United States in 1912, as re- 

 ported to the United States Geological Survey, 

 was 82,438,096 barrels, valued at $67,016,928, 

 compared with 78,528,637 barrels, valued at 

 $66,248,817, in 1911. The output for 1912 

 represents an increase in quantity of 3,909,- 

 459 barrels, or nearly 4.98 per cent., and in 

 value of $768,111, or 1.13 per cent. The ship- 

 ments of Portland cement from the mills in 

 the United States in 1912 are, according to 

 reports received by the survey, 85,012,556 bar- 

 rels, valued at $69,109,800, compared with 75,- 

 547,829 barrels, valued at $63,762,638, shipped 

 in 1911. The shipments therefore represent 

 an increase in quantity of 9,464,727 barrels, or 

 12.52 per cent., and in value of $5,247,162, or 

 8.38 per cent. The average price per barrel 

 in 1912, according to these figures, was a trifle 

 less than 81.3 cents, compared with 84.4 cents 

 in 1911. This represents the value of cement 

 in bulk at the mills, including labor and cost 

 of packing, but not the value of the sacks or 

 barrels. The average price per barrel for the 

 country is about 13.9 cents higher than the 

 average price received for Portland cement in 

 the Lehigh district, where it was sold at the
