The Chillean Government has issued orders 

 that all possible facilities be furnished to the 

 expedition from the Lick Observatory, which 

 will shortly begin its work in that country. 



The American Institute of Mining Engi- 

 neers will hold its eighty-third meeting at 

 New Haven, Conn., beginning on Tuesday, Oc- 

 tober 14, 1902. 



The English Arboricultural Society held its 

 annual meeting in London on August 18. Mr. 

 George Marshall, member of the Royal For- 

 estry Commission, was elected president in 

 succession to Dr. Somerville, of the Board of 

 Agriculture. 



The annual conference on the improvement 

 of the condition of the insane, which met 

 recently at Antwerp, adopted the following 

 resolutions : (1) That the confinement of the 

 insane henceforth be abandoned except in the 

 cases of those recognized as dangerous. (2) 

 That the system of boarding insane persons 

 with families be carried out whenever possible. 



(3) That it is expedient to renew the wish for- 

 mulated at the Congress at Paris for the es- 

 tablishment of schools for special classes of 

 the mentally weak under medical supervision. 



(4) That the manner of placing patients be 

 entirely left to physicians. ('5) That forcible 

 restraint should be condemned. 



A LARGE table, invented by Professor E. C. 

 Pickering, has been constructed in the north 

 building at the Harvard Observatory. It is 

 made in two revolving sections, one above the 

 other, and takes the place of six separate 

 tables used before. In the upper section the 

 annals of the observatory, magnifying glasses, 

 and reference books are kept; in the lower, 

 letters and files. 



The division of mining and mineral re- 

 sources of the Geological Survey, under Dr. 

 D. T. Day, has issued a chart showing the 

 quantity and value of the mineral productions 

 of the United States for the ten years ending 

 with 1901. The value of the total output of 

 metallic ores, such as iron, copper, gold, sil- 

 ver, etc., in 1901 was $524,873,284, against 

 $307,936,189 in 1892; and the value of the 



nonmetallic products, including coal, petro- 

 leum, natural gas, building materials, etc., 

 was $566,351,096 in 1901, against $339,958,- 

 842 in 1892. Prom the arrangement of the 

 metallic and nonmetallic resources on a single 

 sheet, it is possible to follow the yearly change 

 in the production of about sixty of the im- 

 portant mineral products of the country dur- 

 ing the decade. The chart, to be had on ap- 

 plication to the director of the United States 

 Geological Survey, is issued in advance of the 

 report, ' Mineral Resources of the United 

 States, 1901,' which will be ready for distri- 

 bution in the fall. 



Foreign papers report that the vessel Ant- 

 arctic, of the Swedish South Polar expedition, 

 with five scientific members, left Port Stanley, 

 in the Falkland Islands, on April 11 for South 

 Georgia. The expedition stayed in South 

 Georgia from April 22 to June 15, and during 

 this time a detailed survey was made of Cum- 

 berland Bay, one of the largest bays in South 

 Georgia. Investigations into the natural his- 

 tory of Cumberland Bay were carried on, and 

 zoological collections brought home from 

 depths as great as 2,700 meters. Soundings 

 have given depths up to 5,997 meters north- 

 west from South Georgia. The expedition re- 

 turned to Port Stanley on July 4, and will 

 up to the end of September carry on work 

 around the Falkland Islands and in Tierra 

 del Fuego. In October the Antarctic will start 

 for Graham Land, in the Antarctic Ocean.
