Miss Louise B. Dunn, late assistant in botany in Barnard 

 College, made an investigation of the influence of various 

 external factors upon the growth of the capsules of mosses. 



Miss Ada Watterson, assistant in botany, Teachers Col- 

 lege, has carried out some work in the determination of the 

 influence of various chemical irritants upon respiration of 

 fungi. 



Dr. Tracy E. Hazen, assistant in botany, Columbia Uni- 

 versity, has continued his work upon the Confervae of North 

 America. 



Dr. Alex. P. Anderson, assistant in botany, Columbia 

 University, brought his investigations upon the physical prop- 

 erties of starch to an advanced stage early in the year, and is 

 now devoting his entire attention to the economic application 

 of methods of treatment of starchy plant-products for use as 

 foods. 



Dr. E. S. Burgess, professor of biology in the Normal Col- 

 lege, has completed his bibliographical work on the asters, 

 and his results have appeared as volume 10 of the Memoirs 

 of the Torrey Botanical Club. The critical discussion of the 

 species is nearly completed and will appear in volume 12 of 

 the same series. 



Preservation of Native Plants. 



The income of the fund of $3,000, established by the 

 Misses Stokes in 1901, was used, as reported in the October 

 Journal, as prizes for essays on this subject, written by Dr. 

 F. H. Knowlton, Miss Cora H. Clark, and Dr. A. J. Grout. 

 These essays were published in the April, May and June 

 issues of the Journal, reprinted in other journals and widely 

 distributed. The movement attracted much public attention 

 and has doubtless been of value in restricting the indiscrimi- 

 nate picking of wild plants ; it has led up to the formation 

 of a National Society for the Preservation of Wild Flowers, 

 through which much good will be accomplished.
