roughly with our commissioner of Indian affairs. Here also he is
taking the exact view that is taken in the United States by the
staunchest and wisest friends of the Indians. The Indians must be
treated with intelligent and sympathetic understanding, no less than
with justice and firmness; and until they become citizens, absorbed
into the general body politic, they must be the wards of the nation,
and not of any private association, lay or clerical, no matter how
well-meaning.

The Sepotuba River was scientifically explored and mapped for the
first time by Colonel Rondon in 1908, as head of the Brazilian
Telegraphic Commission. This was during the second year of his
exploration and opening of the unknown northwestern wilderness of
Matto Grosso. Most of this wilderness had never previously been
trodden by the foot of a civilized man. Not only were careful maps
made and much other scientific work accomplished, but posts were
established and telegraph-lines constructed. When Colonel Rondon began
the work he was a major. He was given two promotions, to lieutenant-
colonel and colonel, while absent in the wilderness. His longest and
most important exploring trip, and the one fraught with most danger
and hardship, was begun by him in 1909, on May 3rd, the anniversary of
the discovery of Brazil. He left Tapirapoan on that day, and he
reached the Madeira River on Christmas, December 25, of the same year,
having descended the Gy-Parana. The mouth of this river had long been
known, but its upper course for half its length was absolutely unknown
when Rondon descended it. Among those who took part under him in this
piece of exploration were the present Captain Amilcar and Lieutenant
Lyra; and two better or more efficient men for such wilderness work it
would be impossible to find. They acted as his two chief assistants on
our trip. In 1909 the party exhausted all their food, including even
