park of its kind in the tropics. Rio being the railway center of Brazil, 
excursions to the interior are made with comparative ease. 
To any botanist who wishes to study tropical vegetation, and who 
has at the same time an eye for the beautiful, Petropolis and the 
other suburbs of Rio will prove beyond question the most attractive 
place in the world. As compared with the mountains of Java 0 
Sumatra they are civilized, have a much more salubrious climate, ant 
all the conveniences of modern civilized life. The south islanddl 
Hawaii or the south Pacific islands have no such stretches of virgit 
forest, nor such a flora or fauna to explore. Ceylon is hot and uncol 
fortable in comparison, and the mountains of Jamaica and Trinidad 
are uninhabited except by scattered planters. 
It is the writer’s belief that there is no other place in the world 
where such a combination of tropical vegetation, wonderful scenetf; 
civilization, and cool equable climate can be found.—D. G. FatrcHilt, 
Port Said, Egypt, September 21, 1899.

flowers of Verbena urticifolia, the females collecting the pollen.
