Cunard Steam-Ship v. Carey — Opinion of the Court
“ But, as I told you, he is obliged to exercise the care which prudence requires in providing the servant with machinery reasonably and adequately safe for use by the latter; and when the employer is a corporation, which acts through agents, it is responsible for the negligence of those agents who are intrusted with the duty of selecting the machinery, and of exercising, after it is selected, a controlling and governing supervision and rejection when the selected machinery becomes unsafe, and they know, or ought in the exercise of ordinary care to know, of its safety. ”
