perhaps 2,000 feet of the apex. Toward the base it has been 
denuded of the original vegetation and converted into farms. 
Clouds and mists keep the upper portion bathed in moisture and 
the vegetation is very luxuriant except near the top. The entire 
area of its flanks furnishes excellent opportunity for the bo¬ 
tanical collector. The volcano Atitlan is in the Department of 
Solala immediately south of Lake Atitlan, and in general ap¬ 
pearance is much like Agua. It is not however clothed with 
vegetation to the extreme apex — the volcanic ash preventing 
plants from getting a foothold there. The forest covering which 
is very dense, beginning immediately below the line of loose 
material, has not been disturbed except very near the base. The 
volcano Santa Maria in the Department of Quezaltenango is 
likewise clothed with forest vegetation, which reaches the sum¬ 
mit. The eruption that took place in 1902 completely destroyed 
the vegetation on the south and southwest side where a new 
crater of immense size was formed. Many parasitic fungi were 
obtained on these volcanoes, especially on the first named in the 
list, yet the collections must be materially augmented bp future 
trips before a just estimate can be made as to abundance, distri¬ 
bution and character. 
ACKNOWLEDGEMENTS. 
By no means so much could have been accomplished with¬ 
out the cordial assistance and encouragement of many residents 
and citizens of that Republic. First of all thanks are due the 
officers of the Northern Railroad (Ferro-carril del Norte), and 
of the Central Railroad (Ferro-carril Central de Guatemala), 
for courtesies, previously mentioned in this article. The Ameri¬ 
can Minister Plenipotentiary Mr. Combs, the Consul General 
Mr. Winslow, the Vice Consul Mr. Owen, and Rev. W. B. 
Allison a resident missionary, also assisted by kindly advice; 
the pleasures of the trip were greatly enhanced by the courteous 
and cordial reception by their families. It is a pleasure also to 
acknowledge the uniform courtesy of the officers of the Republic, 
and their interest in our explorations, which is at the same time 
a reflection of the liberal and advanced policy, and deep interest 
in scientific and industrial advancement, on the part of the Presi¬ 
dent of Guatemala, Manuel Estrada Cabrera.
