end conference to be held in the State Capitol 

 at Harrisburg on November 17, 18 and 19, 1914. 

 This conference is held under the auspices of 

 the Pennsylvania Department of Labor arid 

 Industry and the Engineers' Society of Penn- 

 sylvania. The purpose of the conference is to 

 enable the employers and employees to work 

 out together the problems before them with 

 reference to increasing the welfare of the em- 

 ployees and the prosperity of the industries. 

 The conference last year was attended by ap- 

 proximately two thousand persons, many of 

 whom were leaders in the labor and industrial 

 world. The first session of the second confer- 

 ence will be called at 10 a.m. on November lY, 

 and the meetings will close at 5 p.m. on No- 

 vember 19. The various sessions of the con- 

 ference will be held in the State Capitol, Har- 

 risburg. In connection with the conference 

 proper, will be held a Safety, Welfare and 

 Efficiency Exhibition which will open on the 

 morning of November 16 and close on the 

 evening of November 20. 



We learn from the Journal of the American 

 Medical Association that the Wesley Memorial 

 Hospital of Chicago has established five fellow- 

 ships to be given yearly to those graduates in 

 medicine who have clinical scientific problems 

 that they wish to solve. The work will be 

 done under a joint board made up from the 

 staff of the Wesley Hospital and the labora- 

 tory departments of the Northwestern Uni- 

 versity Medical School; the clinical work to 

 be done in the hospital and the laboratory 

 work in the laboratory of the medical school. 

 The problems are restricted to those having 

 direct application to clinical medicine and 

 surgery or the specialties. The fellowships 

 are open to any graduate in medicine. The 

 recipient of the fellowship will be required to 

 devote his entire time during the first year, at 

 least, to the prosecution of his investigation. 



Professor I. W. Bailey, of the Harvard 

 Forest School, has returned to the Bussey 

 Institution after an absence of several weeks 

 spent in visiting a number of the middle 

 western universities. The following papers, 

 prepared in collaboration with Dr. E. W. Sin- 

 nott, were read by Professor Bailey:

 fects of Decreasing Temperatures upon the Form 

 and Structure of the Angiosperms. ' ' 



Meeting of Central Botanists, St. Louis, Oc- 

 tober 17: "The Origin and Dispersal of Her- 

 baceous Angiosperms. ' ' 



Missouri Botanical Garden, October 21 : " Some

A MEETING of the New York Section of thg 

 American Electrochemical Society was held 

 on November 10 in Eumford Hall to discuss 

 " Contributions of Chemistry to Illuminating 

 Engineering." The program was as follows: 

 Milton C. Whitaker, Columbia University : " The 

 Improved Incandescent Gas Mantle " ; William 

 C. Moore, National Carbon Co. : " Chemistry 

 in the Development and Operating of Flam- 

 ing Arc Lamps " ; Ralph E. Meyers, Westing- 

 house Lamp Co. : " The New Tungsten 

 Lamps"; E. D. Maily, Cooper Hewitt Elec- 

 tric Co. : " The Quartz Mercury Lamp " ; D.

Pennsylvania so far exceeds all the rest of 

 the states in the value of its mineral products 

 as to stand almost alone. Exclusive of the 

 value of pig iron, , coke and other derived or 

 secondary products not included in the total, 

 the value of Pennsylvania's mineral produc- 

 tion is nearly one fourth that of the entire 

 country; and in 1913, according to figures of 

 the United States Geological Survey computed 

 in cooperation with the Pennsylvania Topo- 

 graphic and Geologic Survey Commission, it 

 equaled the combined value of the production 

 of West Virginia, Illinois, Ohio and California, 

 the next four states in the value of their min- 

 eral product. Pennsylvania derives its min- 

 eral wealth almost entirely from nonmetalli- 

 ferous mining operations. Except for a small 

 amount of copper it produces none of the preci- 

 ous or semiprecious metals, and the only other 

 metal which figures in the total production of
