You may be interested in a letter whioli Pro- 

 fessor Smith has, at my suggestion, wi-itten for 

 Science. I greatly admire your courage in eom- 

 ti Tilling Isis under the lam.entable conditions now 

 existing. The journal is of such high standards 

 that its diseontinuanee would be a serious loss to 

 science. The publication department of The Popu- 

 lar Science Monthly has handed me the enclosed 

 letter and the writer has been informed that it will 

 be forwarded to you. 



The printing of the letter may serve to call at- 

 tention to the fact that the publication of Isis 

 has now been resumied under the editorship of 

 M.. Sarton. 



The N'ational Forest Eeservation Com- 

 mission has approved for purchase 54,744 acres 

 of land for national forests in the "White 

 Mountains, Southern Appalachians and Ar- 

 kansas. The largest tracts purchased are in 

 Georgia, where the resumption of purchase 

 work has been authorized by the commission. 

 An aggregate area of 38,108 acres in Eabun, 

 Union and Townes counties, scattered through 

 thirty-nine tracts, was approved for purchase 

 at an average price of $7,23 per acre. In 

 Alabama, in Lawrence and Winston counties, 

 5,159 acres were approved at an average price 

 of $4.30; in E"orth Carolina, in Macon and 

 Buncombe counties, 1,940 acres were approved 

 at an average price of $4.30 an acre; in Vir- 

 ginia, in Augusta and Shenandoah counties, 

 1,381 acres were approved at an average price 

 of $4.36 an acre in West Virginia, in Hardy

 Garland counties, were approved for purchase 

 at an average price of $3.61 per acre. To 

 date the ZSTational Forest Eeservation Com- 

 mission has approved for purchase 1,702,534

 teen areas of eastern national forests. 



Nature states that with the view of meet- 

 ing the growing demand for technical litera- 



ture, the coimcil of the Chemical Society 

 decided early in 1917 to increase the scope of 

 the library of the society by a more liberal 

 provision of suitable technical works and 

 journals It was also thought that by placing 

 the existing library of 23,000 volumes and the 

 proposed extension at the disposal of members 

 of other societies and associations they might 

 relieve themselves of the necessity of collect- 

 ing and maintaining the literature relating 

 to their special subjects, and assist in the for- 

 mation of a representative library of chemical 

 literature, such as would be difficult to obtain 

 by individual effort. A conference of repre- 

 sentatives of societies and associations con- 

 nected with chemical science and industry 

 was held to consider the means by which other 

 societies, etc., might cooperate in this ex- 

 tension, and financial assistance was after- 

 wards offered by the following societies, etc. : 

 Association of British Chemical Manufac- 

 turers, Biochemical Society, Faraday Society, 

 Institute of Chemistry, Society of Dyers and 

 Colorists, and Society of Public Analysts. 

 Members of these contributing societies, etc., 

 will be permitted to consult the library and 

 borrow books.
