Dr. David Griffiths, student, carried out an extensive study 

 of the Sordariaceae, a family of minute fungi growing on 

 decaying animal matter. 



Dr. Tracy Hazen, student, has been busy with an arrange- 

 ment of the Confervae, a group of light-green Algae of this 

 region. 



Mr. J. E. Kirkwood, student, has been concerned chiefly 

 with embryological questions, especially on plants of the 

 squash family, but has carried to an advanced stage a chem- 

 ical study of germinating cocoanuts. 



Miss Sarah H. Harlow, student, made a study of the mycor- 

 rhizal roots of a number of plants including those of the 

 hemlock from our forest. 



Mr. F. H. Blodgett, Museum Aid, has investigated the fun- 

 gus diseases of carnations, a study commenced at the New 

 York Agricultural Experiment Station, and also certain mor- 

 phological features of Erythronium. 



Mr. Chas. W. Gilman, student, has been engaged in 

 classifying collections of local mosses and others from the 

 State of Washington. 



Mr. R. M. Harper, student, continues his studies upon the 

 flora of Georgia, having spent a portion of the summer collect- 

 ing in that State by means of financial assistance kindly fur- 

 nished by Judge Brown. 



Miss R.J. Rennert, student, made an extended study of the 

 transpiration of twigs and buds in winter. 



My own original studies have been mainly directed towards 

 a better knowledge of the plants of Northeastern North 

 America, though I have given considerable attention to the 

 flora of Porto Rico, based on the specimens secured through 

 the Vanderbilt exploration fund, and also to the collections 

 made in the Yukon Territory by Messrs. R. S. Williams and 

 J. B. Tarleton. I have given all the time possible to the 

 assistance of other members of the staff and students in their 

 investigations. Care has been taken that the research work 

 of the members of the staff should not interfere with their ad- 

 ministrative or curatorial duties.
