over four hundred and fifty miles. Its head-waters are several 
streams rising in the Serra da Mantiqueira, the loftiest peak of 
which, Itatiaiaassu, 10,040 feet, is the Dieb known elevation in 
Brazil. The various streams whieh unite to form the Rio Doce 
flow in a more or less northerly direction from the northern slope

several tributaries, enters the ocean at about 19° 40’ south latitude.
