THE ROOSEVELT-RONDON SCIENTIFIC EXPEDITION 
A REVIEW OF ITS MOVEMENTS IN SOUTH AMERICA IN 1913-14 AND OF 
SOME OF ITS ZOOLOGICAL ACHIEVEMENTS 
By L. E. Miller 
Mammalogist of the Expedition 
HE plan of the expedition, fully de- 
cided upon after consultation with 
the Brazilian Government on arrival 
at Rio de Janeiro, took shape as 
follows: to ascend the Paraguay to the high- 
est navigable point, cross the vast breadth of 
Matto Grosso on mule-back and descend the 
unexplored Rio da Diivida. It was decided 
also that the main purpose of the expedition 
should be an exploration of the Rio da Diivida 
with zodlogical collecting as we moved along 
or as opportunity presented itself. 
The steamship ‘‘ Vandyck”’ remained at 
anchorage in the harbor of Rio de Janeiro 
two days, which gave us ample time to view 
the natural scenic wonders of the harbor, and 
the beautiful city. The greater part of one 
day was spent in the botanical gardens which 
with the avenues of stately royal palms and 
large collections of plants from all parts of 
the tropical world, doubtless surpass anything 
of a similar nature found in South America. 
Here Colonel Roosevelt left the party, accom- 
panied by his son Kermit and Doctor Zahm; 
the remainder of the expedition consisting of 
Mr. George K. Cherrie, Mr. Jacob Sigg, Mr. 
Anthony Fiala and myself, resumed the voyage 
and reached Buenos Aires six days later (Oc- 
tober 27), twenty-three days after leaving 
New York. Wehad stopped a day at Santos, 
Brazil’s great coffee center, and another at 
Montevideo, the capital of Uruguay. 
Although we had read and heard a great 
deal about the city of Buenos Aires, we were 
hardly prepared for the pleasant surprise 
that awaited us. The population of this 
metropolis of the south is in the neighborhood 
of two millions, and the city presents a clean, 
dignified appearance. There is no lack of 
modern edifices, including large hotels and 
splendid theatres; an electric subway was 
just being opened, and the zodlogical park
