PROGRESS OF INLAND DISCOVERY.
Ignorance of the Buenos Ayreans respecting the lands
south of the Salado previously to their Independence.
Colonel Garcia's expedition to the Salt Lakes in 1810.
The Government of Buenos Ayres endeavours to bring about
an arrangement with the Indians for a new boundary. Their
warlike demonstrations render futile this attempt. March of
an army to the Tandil, and erection of a Fort there. Some
account of that part of the country. The coast as far as
Bahia Blanca examined, and extension of the frontier-line
as far as that point. The hostility of the Indians makes
it necessary to carry the war into the heart of their
Territories. General Rosas rescues from them 1500 Christian
captives. Detachments of his army occupy the Choleechel,
and follow the courses of the River Negro and of the
Colorado till in sight of the Cordillera Page 117
