edge, but also to good writing. Aside from his work as editor and 
reviewer, his botanical writings fall into four categories. 
1. TEXTBOOKS.—Professor BARNES played an important part in 
the development of laboratory work in this country. The spirit 
of the Lehrbuch of Sacus had been introduced into this country by 
Professor BrssEy, but many teachers at that time neéded specific 
directions for studying the material called for. To meet this need, 
the then editors of the BOTANICAL GAZETTE, Professors ARTHUR, 
Barnes, and Courter, prepared the Handbook of plant dissection, 
Which was published in 1886. The accident of the names of the 
joint authors and the sequence of their parts in the book led to its 
informal designation as “the A B C of botany.”’ Through the whole 
period of laboratory organization and development this book played 
its part as a guide, and through it the teaching power and technical 
facility of Professor BARNES reached the teachers. 
In 1898 he published his Plant lije, a textbook for secondary 
Schools. This was about the first text in this country that recognized 
physiology and ecology as subjects for study in secondary schools, 
and was considerably in advance of the preparation of the teachers. 
A briefer edition appeared in 1900, entitled Oudlines of plant life. 
His ripened experience as a teacher and an investigator had just 
€xpressed itself in a textbook on plant physiology for college use. 
© was permitted to read the final proofs, so that the work will appear 
just as he had it in mind. This will stand as a permanent record 
of his point of view, of his characteristic and telling way of putting 
things, of his critical analysis of difficult problems and doubtful 
Situations. 
2. Taxonomy.—Like almost every American botanist whose 
training began thirty years ago, his first contact with the subject 
was through the Gray texts, and his first interest was in local floras. 
Various small papers were published, but soon the mosses attracted 
his attention as a group needing investigators at that time. Perhaps 
his first general recognition among botanists came through his 
taxonomic work on this group, the most important publications 
being Analytic key to the genera of mosses (1886); Revision oj the 
North American species of Fissidens (1887); Artificial keys to the 
Senera and species of North American mosses (1890), revised in col-
