Whether an owner of a building retains such control over work to be done and the manner of doing it as to render himself responsible for injuries occasioned by the *126negligence of a contractor and his employees in the performance of the work, depends upon the construction to be given to the contract. Erie v. Caulkins, 85 Penn. St. 247. Railroad v. Hanning, 15 Wall. 649. Eaton v. European & North American Railway, 59 Maine, 520. Cincinnati v. Stone, 5 Ohio St. 38. Newton v. Ellis, 5 El. & Bl. 115. Blake v. Thirst, 2 H. & C. 20.
