bequeathed to the California Academy of Sci- 

 ences and is being prepared for exhibition at 

 the Exposition by Mrs. T. S. Oldroyd, the well- 

 known collector of California shells. 



A GIFT of $15,000 a year for a period of five 

 years has been made to the Egyptian Depart- 

 ment of the Metropolitan Art Museum, by 

 Mrs. Edward J. Tytus, as a memorial to her 

 son, Robb de Peyster Tytus, who died last 

 year. 



The British Board of Trade has arranged 

 for a commission consisting of representatives 

 of the Board of Trade, the Timber Trade 

 Federation of the United Kingdom, and the 

 Mining Association of Great Britain, to pro- 

 ceed to Canada and Newfoundland in order to 

 enquire into the possibility of opening up new 

 sources of supplies of mining timber for use 

 in the coal mines of Great Britain. 



According to a report which has just been 

 issued by the United States Bureau of Mines, 

 the number of men killed in and about 

 quarries in 1913 was 183. The number of men 

 employed in the quarry industry was 106,278, 

 and the death rate per 1,000 employed was 

 1.72, as compared with 1.88 during 1912. The 

 number of men killed in 1912 was 213, the 

 figures for 1913 showing a decrease of thirty 

 deaths or 14 per cent. The figures show that 

 the principal hazards of quarrying appear to 

 be equally divided between explosives, falls of 

 quarry material, and haulage. Accidents 

 from these causes represent nearly two thirds 

 of the fatalities. Albert H. Fay, engineer of 

 the bureau, who compiled the statistics, makes 

 the statement that in France the fatality rate 

 for quarry accidents is seldom more than one 

 in every 1,000 men employed, and in the year 

 1912 was even less than one. In Great 

 Britain, for the ten years 1895 to 1904, the 

 rate was 1.09 for every 1,000 men employed. 



Minnesota far outranks all other states in 

 the mining of iron ore, and diiring the last 

 four years has contributed both in quantity 

 and value considerably more than half the 

 iron ore produced and marketed in the United 

 States, according to the United States Geo- 

 logical Survey. In 1913 the total marketed 



production of iron ore in this country was 

 59,643,098 long tons, valued at $130,905,558, of 

 which Minnesota contributed 36,603,331 tons, 

 valued at $80,789,025. In 1912 Minnesota pro- 

 duced 34,249,813 long tons of iron ore, valued 

 at $61,805,017. Because of its great wealth in 

 iron ores and of their extended development, 

 Minnesota ranks ninth among all the states 

 in the total value of its mineral production. 

 The value of the iron ore produced in the 

 state represents considerably more than 90 

 per cent, of the total output. The value of 

 the mineral products of Minnesota in 1913, 

 exclusive of iron ore, was $5,025,508. These 

 include the products of the stone quarries and 

 the clay pits. 



The United States Bureau of Mines is 

 planning a comprehensive exhibit at the Pan- 

 ama-Pacific Exposition. In arranging the ex- 

 hibit, the bureau has had in mind, not only 

 the value of interesting those engaged in the 

 various mining and metallurgical industries, 

 but also the education of the general public 

 to a better knowledge of the magnitude of 

 these industries and to the efforts which are 

 honestly being made by the miners and mine 

 operators, with- the assistance of the Bureau 

 of Mines, looking toward a more safe conduct 

 of mining and a more efficient utilization of 

 the products of the mines after they are won 

 from the earth. The bureau's exhibit is 

 located in the Palace of Mines and Metallurgy. 

 An automatic duplex projecting machine will 

 continuously show lantern slides illustrative 

 of the activities of the bureau and simultane- 

 ously give descriptions of the lantern slides. 

 Near by will be shown the lay-out of a model 

 hospital, including a receiving room, ward 

 room and operating room, fully equipped for 

 demonstrations by the United States Marine 

 Hospital Service; also a model of a change 

 and wash house, another weKare feature which 

 is being installed at modern mining and metal- 

 lurgical operations. A plan of an ideal mining 

 town will be shown. First-aid demonstrations 

 will be given frequently. An air of reality 

 will be lent to the demonstration by the re- 

 moval of apparently injured men from the 

 exhibition mine beneath the building by hel-
