Few Spanish towns have developed more rapidly than Baracaldo, which nearly doubled its population between 1880 and 1900.
The low flat country round Baracaldo is covered with maize, pod fruit and vines.
Another very important industry is the manufacture of dynamite and other explosives at Baracaldo, closely connected with the mining interests.
Bilbao (pop. 83,306), the capital and principal port, and Baracaldo (15,013), an important industrial town, are described'.
