A. G. Tansley. 
INTERNATIONAL PHYTOGEOGRAPHIC EXCURSION 
(I.P.E.) IN AMERICA, 1913. 
NE of the most pleasing results of the International Phyto¬ 
geographic Excursion in the British Isles organised by the 
British Vegetation Committee in 1911, was the enthusiasm with 
which the visitors from abroad decided to go and do likewise. 
The first outcome of these resolves has been the magnificent 
American tour of 1913, lasting two months (August and September), 
and attended by ten Europeans—Dr. H. Brockmann-Jerosch, Frau 
Dr. Marie Brockmann-Jerosch (Zurich), Professor Engler (Berlin), 
Dr. Ove Paulsen (Copenhagen), Dr. Edward Riibel (Zurich), 
Professor C. Schroter (Zurich), Dr. T. J. Stomps (Amsterdam), 
Mr. A. G. Tansley, Mrs. Tansley (Cambridge), Professor C. von 
Tubeuf (Munich). 
The tour was arranged by Professor Henry C. Cowles 
(Chicago) and Professor F. E. Clements (Minneapolis), but owing 
to various circumstances the great bulk of the work of organi¬ 
sation rested on the shoulders of Professor Cowles, to whom the 
deepest gratitude of all the members of the party is due, not 
only for the completeness and perfection of the arrangements, but 
also for his unfailing kindness, good humour and self-sacrifice 
throughout the trip. Without these qualities in a leader, indeed, 
the best organised tour might well turn out unsatisfactory and 
even unpleasant. 
Professor Cowles had two able assistants, Mr. George D. 
Fuller (Chicago), and Dr. George E. Nichols (New Haven), one 
of whom attended to the railroad tickets, and the other to the 
baggage of the party, but they by no means confined themselves to 
these very necessary tasks. Both were of the greatest assistance 
to the European visitors in the many unfamiliar situations inci¬ 
dental to American travelling, and both most substantially helped 
Professor Cowles to make the journey a profitable and pleasant 
one. Both Mr. Fuller and Dr. Nichols also took numerous 
photographs throughout the tour ; and these will be available for 
members of the party, and will no doubt form a valuable record of 
the trip.
