    MASTIN, Respondent, v. BEAVER CO., Appellant.

    October 20, 1915.)
    Action by Andrew Mastín, an infant, etc., against the Beaver Company.
   PER CURIAM.

Judgment and order affirmed, with costs. Held that, while it was error to allow the expert witness Dallor to give his opinion as to what caused the bolt to break, the evidence elicited was not prejudicial.
