Pontine Marshes

Pontine Marshes, a district, 26 m. by 17, in the S. of the Campagna of Rome, one of the three malarial districts of Italy, and the most unhealthy of the three, extending about 30 m. in length and 10 or 11 in varying breadth, is grazing ground for herds of cattle, horses, and buffaloes. Many unsuccessful attempts have been made to drain these marshes.
