Judge Taylor thought who was browbeating whom?

Judge Taylor said the witness was browbeating Atticus.

“Now let’s consider this calmly—” began Atticus, but Mr. Gilmer interrupted with an objection: he was not irrelevant or immaterial, but Atticus was browbeating the witness.
Judge Taylor laughed outright. “Oh sit down, Horace, he’s doing nothing of the sort. If anything, the witness’s browbeating Atticus.”
