What does Mr Nathan say about the intruders in his garden?

From the text:

“Mr. Radley shot at a Negro in his collard patch.”

“Oh. Did he hit him?”

“No,” said Miss Stephanie. “Shot in the air. Scared him pale, though. Says if anybody sees a white nigger around, that’s the one. Says he’s got the other barrel waitin‘ for the next sound he hears in that patch, an’ next time he won’t aim high, be it dog, nigger, or—Jem Finch!”
