UREDINALES OF GUATEMALA 
and a buoyant disposition that makes light of hardships. A few brief 
excerpts from his letters to the author will illustrate the manner in 
which he searched for rusts with such eminent success. 
A week after reaching Guatemala City on his first visit, Professor 
Holway started for Antigua "over a road with two-foot holes and two- 
foot boulders and much dust," as he says, and at a lunch station, 
"within ten rods of the hotel, collected twenty-five rusts." The 
next day he writes from San Rafael: "Arrived here about noon, and 
although the afternoon was misty and dark I found about fifteen more 
rusts." Two days later he writes from Antigua: "Grand place! 
Volcanoes 8,000 feet directly above the town. Out three hours and 
found everything rusted here that was not at San Rafael." A single 
extract may be taken from the letters of the second trip. On Feb- 
ruary 22 he writes from Mazatenango. "This is the most surprising 
place! A fine, perfectly clean hotel, good food, no mosquitoes, the 
grandest and most luxuriant vegetation, and fine views of the Volcans 
de Atitlan and Santa Maria! There is a fly in the ointment — ticks 
the botanist has always with him." On his third trip, a letter written 
the middle of January says: "I wish you could have been with me at 
San Felipe and seen the Volcan de Santa Maria, the fine tree ferns, the 
brilliant orchids blooming on the tree trunks, etc., etc. — ^There were 
some ticks." Upon reaching Huehuetenango, a much more northern 
locality than any hitherto explored, ninety miles from the railroad, 
that is "three days' mule ride," and which promised to be especially 
rich in rusts, a telephone message was received giving warning of the 
changed attitude toward foreigners due to recent developments in the 
war. It was deemed advisable to make a hasty departure for Guate- 
mala City, and as soon as arrangements could be made a steamer was 
taken from the west coast for return to the United States. 
In the last few years there have been a number of notable explora- 
tions for rusts in the different parts of the American tropics, but doubt- 
less none of them has yielded so rich a harvest of additional species 
for the North American flora as the work of Professor Holway in 
Guatemala. Part of these new species are forms previously known 
only from South America, but very many more are species new to 
science. As a presentation of the rust flora of Guatemala, however, 
the list as it now stands must be accepted as only a good beginning. 
Even the species given in many cases require the discovery of addi- 
tional stages in order to make known their full life cycle. It must also
