3. Altitudinal Distribution. 
The papers that deal with the altitudinal distribution of plants in North 
America are comparatively few in number. 
For the White Mountains, we have the List of Plants found in New 
Hampshire only on Alpine Summits by C. H. HITcCHcock and published in 
his report on the geology of New Hampshire in 1874. . J. W. CHICKERING 
contributed to Field and Forest (1876) a Catalogue of the Alpine and Sub- 
alpine Flora of the White Mountains and C. G. PRINGLE the same year, an 
article to the American Naturalist on the alpine and subalpine plants of Ver- 
mont. “Among the Clouds” for 1900 gives a list of alpine plants of Mt. 
Washington made by the Appalachian Club. The alpine flora of Mt. Katahdin 
has been investigated by the New England Botanical Club, L. H. HARVEY, the 
results of whose labors appear in the fifth and third volumes of Rhodora, and 
by an ecologic party under the leadership of H. C. CowLEs of the University 
of Chicago, while the ascent of the same mountain by J. W. HARSHBERGER 
is described in the fifth volume of the Plant World. The Bulletin of the 
Torrey Botanical Club for 1890 gives an account of the flora of Mt. Monad- 
nock by WALTER DEANE. Plants of the Summit of Mt. Marcy, one of the 
few alpine peaks in Adirondack mountains, is the title of an article by CHARLES 
H. PECK in the Bulletin of the New York State Museum for October 1899. For 
the mountains of the southern states, the list is even smaller, a ss ag 
by J.W. HARSHBERGER on the ecology of mountainous North Carolina published 
in the Botanical Gazette for 1903, one by PINCHOT and ASHE on the forests 
and.one on the altitudinal distributions of ferns with several shorter papers by 
JOHN K. Smaıı practically completes the enumeration. The mountains of the 
western United States and of Mexico have been investigated to some extent. 
THOMAS MEEHAN, T. S. BRANDEGEE and HENRY GANNETT have contributed 
to the Botanical Gazette articles on the timber line of. high mountains. ‚As 
bulletins of the North American Fauna we have contributions of this subject 
in the results of a biological survey of Mount Shasta, California ( 1899) and of 
the San Francisco mountains (1890) by C. HART MERRIAM. ei; 
The Rocky Mountain alpine region has been investigated by u 6
