The Second Jungle Book by Rudyard Kipling Chapter 9 Page 10

“I hunted in Cold Lairs, which place thou hast not forgotten.

And the thing I hunted fled shrieking past the tanks and to that house whose side I once broke for thy sake, and ran into the ground.”

“But the people of Cold Lairs do not live in burrows.” Mowgli knew that Kaa was telling of the Monkey People.

“This thing was not living, but seeking to live,” Kaa replied, with a quiver of his tongue. “He ran into a burrow that led very far. I followed, and having killed, I slept. When I waked I went forward.”

“Under the earth?”

“Even so, coming at last upon a White Hood [a white cobra], who spoke of things beyond my knowledge, and showed me many things I had never before seen.”
