losses which the western livestock industry 

 faced, the National Forest ranges were opened 

 early. At the same time, the number of stock 

 permitted for the present season was raised to 

 the maximum consistent witli safeguarding 

 future productiveness. It is fully recognized 

 that the increases which have been made in the 

 allowances of stock on the national forests in- 

 volve danger that the range will be depleted 

 through overgrazing, but it is believed by the 

 grazing experts of the government that the 

 emergency increases made can be taken care of, 

 at least this year, without material sacrifice of 

 productive capacity. The condition of the 

 ranges is, however, being carefully watched. 

 Eeliance is placed also on the special efforts 

 being made to secure the most intensive utili- 

 zation consistent with sustained productive- 

 ness, by improved methods of handling the 

 stock. Better salting methods and the de- 

 velopment of new watering places are among 

 the means employed for this purpose. At the 

 close of the grazing season a careful examina- 

 tion will be made of the range on each forest 

 to determine its condition and to find out how 

 many cattle or sheep it will support next sea- 

 son. On areas which are found to be over- 

 grazed, an attempt will be made to shift the 

 surplus stock to range which can stand the 

 strain better. While the grazing oificials do 

 not think that the increase could be carried 

 indefinitely without serious damage to the for- 

 age, regulated grazing has brought about a 

 steady improvement of the range and some 

 areas will probably be able to support the 

 larger numbers permanently. 



During the last week of September nine in- 

 dustrial fellows of the Mellon Institute of In- 

 dustrial Research entered the service of the 

 government. The names of these men, all of 

 whom are chemists, are as follows: Dr. Frank 

 O. Amon, Dr. Harold S. Bennett, Mr. A. S. 

 Crossfield, Mr. W. J. Harper, Mr. C. E. How- 

 son, Dr. E. W. Miller, Mr. Eay V. Murphy, Mr. 

 W. E. Vawter and Mr. C. L. Weirich. Messrs. 

 Amon, Bennett, Howson, Miller, Murphy, Vaw- 

 ter and Weirich have received commissions as 

 first lieutenants. In addition, three other In- 

 dustrial Fellows, Messrs. C. 0. Brown, G. F. 



Gray and R. P. Eose had previously been com- 

 missioned as captains; A. H. Stewart has en- 

 tered the aviation service and C. N. Ivy has 

 been appointed a second lieutenant in the Engi- 

 neering Corps. 



The dean of Sibley College, Cornell Univer- 

 sity, Professor Albert W. Smith, has received 

 leave of absence for the year 1917-18 in order 

 that he may serve as consulting engineer to 

 the Mathieson AUtali Works at Saltville, Vir- 

 ginia. Professor Dexter S. Kimball, head of 

 the department of machine design and indus- 

 trial engineering, has been appointed acting 

 dean of Sibley College. 



Professor J. C. Br.vdley, of Cornell TJnivev- 

 sity, and Professor Edwin C. Van Dyke, of the 

 University of California, have exchanged work 

 for the current year. Although both are gen- 

 eral entomologists. Professor Van Dyke is an 

 authority on the coleoptera, while Professor 

 Bradley is a specialist on the hymenoptera. 



Professor John C. McLennan, Ph.D., head 

 of the department of physics of the University 

 of Toronto, and member of the Canadian Com- 

 mission on Chemical Eesearch, is among the 

 first group to receive the honor of the new 

 Order of the British Empire. 



The Medical Club of Philadelphia will give 

 a reception in honor of Dr. Morton Prince, of 

 Boston, on October 19, at the Belle^iie-Strat- 

 ford Hotel. 



Dr. Santos Fernandez, president of the 

 Cuban Academy of Science, and one of the 

 most distinguished eye surgeons of Cuba, was 

 the guest of honor at a luncheon given October 

 2, by Dr. William Campbell Posey, of the Wills 

 Eye Hospital, Philadelphia. 



According to Nature, the seventieth birth- 

 day of Professor S. Hoogewerii, formerly 

 rector of the Technical High School of Delft, 

 was recently celebrated by his friends and 

 pupils. Professor HoUeman briefly reviewed 

 Hoogewerff's work, carried out conjointly with 

 the late Dr. Van Dorp, on the cinchona alka- 

 loids, on isoquinoline, and on the production 

 of anthraeilic acid from phthalimide. The 

 latter reaction became a step in the manu- 

 facture of synthetic indigo. On behalf of a
