appointed Editor-in-chief. Dr. Grout accepted this office with reluctance, and 

 only after great pressure from friends of the enterprise had been brought to bear, 

 as absolutely no one could be found at that time willing to undertake the work. 

 Dr. Grout took it at great personal sacrifice to ensure its continuance, adding 

 thereby a heavy burden to his High School duties. The Advisory Board, con- 

 sisting of the officers of the Society, became responsible for the publication, and 

 four Associate Editors were appointed representing the four groups treated of in 

 The Bryologist, namely: Acrocarpous Mosses, Prof. John M. Holzinger; 

 Pleurocarpous Mosses, Dr. George N. Best; Hepatics, Dr. Alexander W. Evans; 

 Lichens, Prof. Lincoln W. Riddle. 



It may not be out of place at this time to emphasize what the Society has done 

 in the way of promoting interest in the mosses, and indirectly in making possible 

 such books as Dr. Grout's " Mosses with a Hand-lens"; a second edition " Mosses 

 with hand-lens and Microscope, including the Hepatics"; and the third large 

 volume "Mosses," published in 1903. Prof. Fink has repeatedly expressed to 

 me his appreciation of the way in which his series of articles was illustrated and 

 published, as they brought him to the notice of a wide circle of readers and cre- 

 ated a demand for, and fostered further studies culminating in his volumes on 

 the lichens. And we all take pride, I know, in the volume "How to Know the 

 Mosses," recently pubUshed by Mrs. Elizabeth M. Dunham, one of our members 

 since 1904. The series of special articles which appeared in the earlier volumes, 

 are worthy of note, as they formed the first popular treatment of the genera, 

 save for that pioneer series of Mrs. Britton's in The Observer. For many of us 

 those articles were the foundation on which we reared our later work — they 

 formed the bridge which connected with the Manual. 



Then in field work we might fairly claim to have promoted exploration when 

 we recall the collections of A. S. Foster in Oregon and Washington; Severin Rapp 

 in Florida; A. L, Brinkman in British Columbia and Alberta; the late C. C. 

 Kingman in Southern California; Miss Crockett in Maine, and gthers who con- 

 tributed ample material for the curators to work up. We should also mention 

 the large number of foreign correspondents, men and women of note in all coun- 

 tries of Europe and Australia, to whom we owe gratitude for material gifts, also 

 for their inspiration to nobler endeavor. 



It should be explained that, almost from the first, hepatics and lichens had 

 been sent in for determination, as beginners often confused the groups when 

 found growing together with the mosses. I began at once to form a Chapter 

 Herbarium of mosses, and it was exhibited at the second meeting of the Sullivant 

 Moss Chapter held June 27, 1900, in the Museum Building of the New York 

 Botanical Garden, consisting of 153 sheets. At this time it was proposed to add 

 hepatics and lichens, and Mr. William C. Barbour undertook the hepatics, and 

 Mrs. Carolyn W. Harris, the lichens. The first number of her long and fine 

 series was on "The Usneas," illustrated by a beautiful plate in January, 1901. 

 In the next issue, April, Mr. Barbour began his series on Hepatics with a study 

 of Marchantia and Conocephalum, and each took charge of the herbarium for 

 their special group. Thus was started the three-fold herbarium of the Society
