The illustrated series of twelve papers published in The Bryologist is 
well known to all readers of our journal. In these articles, Mrs. Harris aimed 
to give such knowledge of the common foliose and fruticose lichens as would 
enable one to know them from the descriptions and illustrations, aided by 
the hand lens. There is always some doubt in the minds of botanists 
regarding the scientific value of short diagnoses of lower plants, in which 
the microscopic characters are omitted, but there is good evidence that 
some persons became interested in lichens through these papers, which were 
well illustrated. Mrs. Harris wrote in 1901: “ I am trying in my articles to 
describe the lichens so that they can be determined with the hand lens. I 
know that I am attempting a good deal, but with many of the lichens, I 
believe this is possible.’’ In 1903 she wrote thus: “Among mycorrespond- 
ents are a number who are not only interested but ready to begin work. 
Surely we should have a club or chapter for the benefit of the beginners as 
well as the students.” The last quotation is from a letter written only a 
short time before the last of the series appeared and indicated that their 
author had succeeded in interesting a number of persons. Doubtless these 
as well as several students of lichens were sorry when the series of papers 
was finally closed after only about twenty-four genera had been covered. 
However, these papers were certainly valuable in interesting readers in 
lichens; and a number of collectors were attracted to the study of lichens 
through them. 
It seems that Mrs. Harris became especially interested in the genus 
Cetray'ia, even before this series of papers was begun. This was probably 
due to observations in the field, in the region where these plants are abund- 
ant. In one letter, she asks for specimens of species of the genus, “both 
native and foreign,” and says: “The Cetrarias have always been particu- 
larly interesting to me.” Five years later she wrote; “The Cetraria 
monograph is still a dream, but I hope it will prove something more later.” 
In 1907 occurred the death of Mr. Harris; and shortly after his death, 
Mrs. Harris suffered an attack of pneumonia. Tne sickness and death of 
Mr. Harris and her own illness interrupted her work on lichens for a time, 
but in 1908 she was again collecting and studying, and from this time on 
until her last illness, the writer occasionally received specimens from her for 
examination. She spent the winter of 1908 in Washington, where she 
enjoyed working with Miss Mary F. Miller, who has charge of the lichen 
department in The Bryologist. It was during this winter in Washington 
that the writer met Mrs. Harris and enjoyed several conversations with her 
regarding lichens and lichenists. No words could add to the high regard for 
the pleasing personality of Mrs. Harris, held by all who knew her personally. 
There was abundant evidence of refinement in her beautiful letters; but the 
poise and gentleness of character were much more apparent in personal 
acquaintance. 
Though her papers deal with macroscopic characters, Mrs. Harris knew 
her plants microscopically and took special delight in talking or writing 
about her herbarium specimens. Her herbarium, books and working outfit
