 mind in the course of an investigation,, and his methods of

 student taking up research in the biological sciences, who wants 

 training in the use of the experimental method and interpretation 

 as practiced by a scientific mind of the highest type, as well 

 as the technique to which' most research teachers are solely 

 addicted. It has not the usual dryness of a textbook — the play 

 of logic, suspense and triumphant experiment reads like a Dumas. 

 Duclaux has written a most inspiring and charming book, and

 rendered available to English readers. — Harry Braun.

A meeting of the Club was held at the New York Botanical 

 Garden at 3.30 p.m. Professor R. A. Harper presided. There 

 were 19 persons present. 



The minutes of the meetings held February 25 and March 10

Mr. Ludlow Griscom and Mr. Elba E. Watson were proposed 

 and elected to membership.

 ' Field Committee, instead of Dr. F. W. Pennell, was announced. 



The scientific program consisted of a discussion by Mr. 

 Norman Taylor of the flora of Mount Marcy, New York, above 

 timber-line. Twice during the season of 1919 did Mr. Taylor, 

 in cooperation with others stuying the vegetation of the state, 

 visit the summit of Mount Marcy. Timber-line was noted 

 at 4,300 feet altitude, and the factors controlling this were 

 considered. Various floras occur on bog land, dry slopes, rock 

 outcrops, etc., and a list of all species seen were made. This 

 was compared with the list made about 1880 by the late Dr. 

 C. F. Peck. 



Only 67 species were found above timber-line, and of these
