Pilcomayo

Pilcomayo, a South American river, rises in Bolivia, and has a course of over 1,500 miles, first S.E. past Chuquisaca, then, after receiving the Pilaya, S.W. between Argentina and Paraguay, falling into the Paraguay a few miles S. of Asuncion. About 100 miles from the mouth it divides into two branches, one of these again dividing into two. The rapid current in parts, and shallowness in the dry season, render navigation well-nigh impossible.
