The vats were five feet deep, and on top of the water floated a three-and-one-half-foot-deep layer of oil. Oklahoma Territory's first vats were installed outside Pawnee, and in Indian Territory the first appeared near Wewoka, in the Seminole Nation. Another was built at Noble in 1898, near the southern border of Oklahoma Territory. Crude oil was only partly effective, and in 1910 it was replaced by a more lethal solution containing arsenic.
