[N. S. Vol. XXXI. No. 796 



for the coming year, and these officers were unan- 

 imously elected: 



President — C. R. Mann, University of Chicago. 



Secretary-Treasurer — Eugene R. Smith, Brook- 

 lyn Polytechnic Institute. 



Members of the Executive Committee — J. T. 

 Rorer, William Penn High School, Philadelphia; 

 W. Segerblom, Phillips Exeter Academy; I. N. 

 Mitchell, State Normal School, Milwaukee, Wis. 



Professor C. H. Judd, of the University of 

 Chicago, addressed the federation on the topic, 

 " Scientific Experimental Investigation of Educa- 

 tion." The speaker indicated that opinions con- 

 cerning education were usually based upon rather 

 vague and uncertain data. He urged that prob- 

 lems in education were capable of solution by 

 scientific experiment and that they should be 

 solved in that way. Several experiments were 

 presented as types which might be followed. 



Mr. H. R. Linville, of Jamaica, N. Y., presented 

 an address on " Old and New Ideals in Biology." 



The meeting adjourned subject to the call of the 

 executive committee. C. R. Mann,

THE AMERICAN ASSOCIATION OF 

 ECONOMIC ENTOMOLOGISTS 

 The twenty-second annual meeting of the 

 American Association of Economic Entomologists 

 was held at the Harvard Medical School (Brook- 

 line), Boston, Mass., December 28 and 29, 1909. 

 The first session was called to order by President 

 W. E. Britton, of New Haven, Conn., who pre- 

 sided throughout the meeting, and who delivered 

 the annual address on " The Official Entomologist 

 and the Farmer." The program was crowded with 

 papers which were of great economic importance 

 to the entomologist and the agriculturist, al- 

 though a few were more technical in character 

 and dealt with some of the fundamental prin- 

 ciples of scientific investigation of entomological 

 matters. A discussion of different methods used 

 in research work was of particular interest, as 

 were also the reports of the progress that is being 

 made in the field and parasite work in New 

 England for the purpose of controlling the gypsy 

 and brown-tail moths. A report by Dr. W. P. 

 Headden, of Colorado, concerning the injury to 

 fruit trees caused by arsenical spraying and the 

 discussions that followed brought out many new 

 ideas on this important subject. An exhibit made 

 by the local entomologists and members which 

 was held in an adjoining room contained samples 

 of apparatus and breeding devices, as well as 



insect collections, which added much interest to 

 the meeting. On Tuesday evening the association 

 and the Entomological Society of America were 

 the guests of the Cambridge Entomological Club 

 and on Thursday morning the members had the 

 opportunity of witnessing a spraying demonstra- 

 tion at Arlington with high power sprayers, as 

 the guests of Mr. H. L. Frost. 



The attendance at each session numbered over 

 100 members and visitors, nearly every section of 

 the United States and Canada being represented. 



The association commended the work which is 

 being done to control the gypsy and brown-tail 

 moths in New England, endorsed the bill before 

 Congress to provide for the establishment of 

 standards of purity of insecticides and fungicides 

 and advocated the passage by Congress of a 

 national law to prevent the importation of dan- 

 gerously injurious insects and fungus diseases 

 from foreign countries. 



The report of the secretary showed that the 

 association was increasing in membership and was 

 in good financial condition. The Journal of Eco- 

 nomic Entomology, which is the official organ of 

 the association, was also reported by the business 

 manager to be in a thriving condition. 



The following officers were elected for the en- 

 suing year: 



President — Professor E. D. Sanderson, Durham, 

 N. H. 



First Vice-president — Dr. H. T. Fernald, Am- 

 herst, Mass. 



Second Vice-president — Professor P. J. Parrott, 

 Geneva, N. Y. 



Secretary — A. F. Burgess, Washington, D. C. 



SOCIETIES AND ACADEMIES 



THE GEOLOCICAL SOCIETT OF WASHINGTON 



At the 226th meeting of the society, held at 

 the George Washington University on Wednesday, 

 January 26, 1910, Mr. Edson S. Bastin informally 

 exhibited specimens of pegmatites whose quartzes 

 had been tested by Messrs. Wright and Larsen. 



Regular Program 

 Some Pegmatites from Southern California: W. 



T. SCHALLEB. 



The pegmatites of Southern California which 

 have been exploited for their valuable gem min- 

 erals (tourmaline, spodumene, etc.) are granitic 

 rock bodies filling fissures in gabbro. Many of 

 these bodies consist of two parts of approximately 

 equal thickness — namely, an upper coarse granite 

 and a lower fine-grained banded garnet aplite.
