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- 

 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, 1866, of his safe 

 arrival in Pard, 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 farthei, 

 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.
