536 APPENDIX. 
and after passing Diamantina explored several arms of this great 
stream. The collections he made in this region are of special in- 
terest with reference to those gathered by Messrs. Hartt and Cope- 
land on the lower course of the same rivers, and in many other 
streams along the Atlantic coast between Bahia and Rio de Ja- 
O 
neiro. Having accomplished this part of his journey, Mr. Ward 
crossed the San Francisco at Januaria, making a number of excur- 
sions in that vicinity; then passing in a northwesterly direction 
over the ridges which separate the valley of the San Francisco 
from that of the Tocantins, he followed the whole course of this 
great stream to the Amazons. It was a daring and adventurous 
journey to be accomplished with no other companionship than that 
of the camarado who served him as guide, or the Indian boatmen 
who rowed his canoe, and it was a day of rejoicing for our whole 
party when we heard, in the month of January, 18G6, of his safe 
arrival in Para, whence he embarked a few weeks later for the 
United States. 
From Lagoa Sancta, where they parted from Mr. Sceva, Messrs. 
St. John and Allen kept on to Januaria together, but at this point 
Mr. Allen, whose health had been failing from the time he left Rio 
de Janeiro, found himself unable to prosecute the journey farther, 
and he resolved to strike across the country to Bahia, taking in 
charge the collections they had brought together thus far. After a 
short rest at Januaria, he made his way to Chique-Chique on the 
Rio San Francisco ; and his separate journal begins from the time 
he left this point, on his journey to Bahia. It gives a very full 
account of the physical features of the region through which he 
passed, of the geographical character of the soil, and of the distri- 
bution of plants and animals, including many original observations 
concerning the habits of birds, with a detailed itinerary of the route 
through Jacobina, Espelto, and Caxoeira. Prostrated by illness as 
he was, he has nevertheless furnished a report the character of 
which shows how completely his interest in the work overcame the 
lassitude of disease.
