Offerings met with a scant response. Mr. A. H. Brinkman of Dowling, 

 Alberta, Canada, has on foot a most excellent plan of establishing exchanges, 

 which merits quick collaboration among us. 



With the return of Dr. Conklin to his old place at the helm, things will soon 

 be bettered. Naturally the best way to welcome him will be by nearly over- 

 whelming him with Society work.

Report of the Lichen Department for 1919 



During the past year interest in the study of Lichens has continued una- 

 bated. 



The herbarium has been enriched by several quite generous contributions; 

 two of these, however, having been received too late to be mounted this year. 

 Of the specimens received during the early part of the year, 55 have been mounted, 

 making the number now in the herbarium 344c. 



Our list of contributors is headed by Dr. N. L. T. Nelson, Dr. O. E. Jennings, 

 and Miss Alice Eastwood. Dr. Nelson's contribution was collected in Texas, 

 and contains some interesting specimens from that part of the world. Dr. Jen- 

 nings contributed two different collections, one collected in Ontario, and the 

 ether in Florida. Miss Eastwood's contribution is a most interesting collection 

 from Hawaiian Islands; none of these specimens have as yet been mounted. 

 Other contributors are: Mrs. M. A. Noble, who sent specimens from Florida; 

 Mr. S. Rapp, who, too, sent specimens collected in Floiida; Rev. H. Dupret, 

 who sent specimens collected near Montreal, Canada; Mrs. Ella L. Horr, and 

 Mr. P. G. M. Rhodes. Mr. Rhodes never forgets us, and this year has sent us 

 some specimens collected in England. 



Each year the curator is asked by some student contemplating the study of 

 Lichens, what book or books, he would recommend, for the beginner, and, he 

 invariably recommends first. Dr. Schneider's "A Guide to the Study of Lichens, " 

 (the "Guide " holds a warm spot in his heart, it is the book that got him interested 

 in the study of these interesting forms of plant life); and, second, but not least, 

 that he get a copy of Prof. Fink's "The Lichens of Minnesota. " With these two 

 books, together with an earnest desire, of wanting to know, and the help of some 

 sympathizing friend, willing to help, progress is bound to be made. Don't expect 

 to master the study of Lichens in one summer, it is hard work, and only a strong 

 interest will keep you at the work. The curator is willing to do his part as sym- 

 pathizing friend, he only too well knows the value of such friends. After you 

 begin to know somthing about Lichens, you will soon learn to value other' works, 

 and will acquire them. 



Before leaving this subject, I must not forget to call the beginner's attention 

 to the many excellent articles in The Bryologist. and especially to the following:
