he had already added thirty-five specimens to all that had been 

 hitherto reported. Since that date he has continued actively to 

 prosecute this work and has secured .many more. Too great 

 praise cannot be bestowed, either upon him for his successful 

 method of work and his untiring zeal and industry, nor upon 

 the Woman's College and its able president, Dr. John F. Goucher, 

 for the liberal spirit shown, the keen scientific interest mani 

 fested, and the substantial aid rendered in advancing this work. 

 I also stated in the paper last referred to that through the 

 generosity of President Goucher and all connected with that in 

 stitution this entire collection had been loaned to the United 

 States National Museum, and turned over to the Department of 

 Fossil Plants for systematic elaboration, and the additional speci 

 mens, as fast as they were discovered, have also been regularly 

 sent to Washington to join the rest. I had already commenced 

 work on the important material of the same general nature from 

 the Black Hills, an account of which was given in the paper 

 presented to this Society of which I have spoken. It was de 

 cided to embody all the material in the Museum and all that 

 could be secured from any American deposits in one general 

 monograph of the Fossil Cycadean Trunks of North America, 

 Dr. F. H. Knowlton to assume charge of all that pertained to the 

 microscopic study of the internal structure and I to deal with 

 the external and macroscopic aspects. I had hoped to have 

 completed my part of the work before this, but many causes 

 conspired to retard progress. Other pressing duties, both in the 

 field and in the office, reduced the amount of time that it was 

 possible to devote to it. The necessity for seeing the European 

 specimens practically obliged me to spend a season on the other 

 side of the Atlantic, the results of which had to be worked up 

 and published.* The amount of labor involved was also very 

 great, and the progress made is as satisfactory as could be ex 

 pected under the circumstances. Much has been done on all 

 classes of the material, but latterly I have been devoting myself 

 chiefly to the Maryland specimens. It has been necessary to 

 study anew all those obtained by Tyson, now in the Geological 

 Museum of Johns Hopkins University, ample facilities for which 

 have been generously extended to me by Professor W. B. Clark. 

 Professor Uhler has also kindly allowed me to describe those in 

 the Museum of the Maryland Academy of Sciences, and he sent
