112 NEW YORK ZOOLOGICAL SOCIETY 
In the course of our residence at Kartabo we have learned 
that it is possible for persons wholly unused to the tropics and 
who have never even camped out before, to live in comfort and 
health in double-roofed tents, sleeping with the entrance flaps 
open, without mosquito nets, at the very edge of the jungle and 
a few feet distant from the river. And this, not for a few weeks 
merely, but for a year at a time, throughout all four seasons— 
the two rainy and the two dry, which are so remarkably distinct 
in this district. The success of these regulation United States 
army tents has been greater than I could have expected. To go 
through the heaviest of long rainy seasons without leaking a 
drop, or to have one’s clothing without mold during that period 
is a record better than many Georgetown houses can boast. A 
single lantern keeps vampires at a distance, and mosquitoes and 
flies are unknown, while it is a radical refutation of the general 
idea of the tropics to have to sleep under a blanket every night. 
In spite of the presence of perai, electric eels and poisonous 
sting rays, all of which are found near by, the entire staff bathes 
daily, often swimming far out into the river, and we believe that 
this exercise does much toward keeping us fit. We have learned 
that the most delicious meat of the Colony is bushmeat, and two 
Indians provide the accourie, labba, maam, monkeys, marudis, 
warracabras, bushpigs and deer which make up most of our 
bill of fare. 
As far as actual exploration goes, we have added consider- 
ably to the general knowledge of the district. The area in which 
we work we have carefully mapped, and divided into numbered, 
one hundred foot squares. But the life of the jungle is so omni- 
present and abundant at our very door we seldom have gone be- 
yond a radius of three miles, while nine-tenths of our investiga- 
tions are carried on within a half mile of our laboratory 
bungalow. 
During the seven months from June to December, 1920, we 
have welcomed about seventy visitors to the Station, while actual 
workers on the staff have numbered seventeen. 
Some of these investigators with their special problems are 
as follows: 
I. W. Bailey, Harvard University—Relation of Ants to Cer- 
tain Plants. 
William Beebe, Columbia University and Zoological Society 
—General Evolutionary Problems in Ornithology and Ecology.
