During the circus season in Hillsboro last week, a young blood from Portland whose name we are unable to learn, took occasion to grossly insult a respectable young lady of that town by the name of Miss Southworth. Not receiving any answer to his insulting inquiries, he persisted in dogging the steps of the young lady continually, casting reflections on her good name. The young lady's brother appeared on the ground shortly after, and upon her relating the circumstances to him, he at once proceeded to give the young man a good drubbing. It was fully half an hour before the brother finished his good work, and when he was satisfied, the Portland sport looked like he had fallen through the lower floor of a slaughter house.
