They advanced slowly for several rods. Then they became aware of an unpleasant odor.

“I think I know everything now,” said Mr. Lewis, and Bob’s father nodded. “That’s a dead animal—probably an antelope. It has been killed by some other animal—a lion, maybe.”

As they advanced they kept their eyes open for any dangerous creature that might return to the carcass, but saw nothing.

Mr. Lewis had surmised correctly. The kill was a wildebeest, a member of the antelope family. It had apparently been dead only a short time, and only a little of the flesh was torn from the body.

“What do you suppose killed that?” asked Bob.

Simba [lion],” spoke up Noko at once.

“You think so?” queried Mr. Lewis.

Noko nodded vigorously.

Simba he come back night. Eat all simba want of nyumbu.”
