In 65 C.J.S., p. 848, sec. 174, it is said, “While it has been held that the doctrine of assumption of risk, in its primary or usual meaning, is limited to controversies between master and servant and is not applicable in the absence of any contractual relation between the parties, there is ample authority for the view that in its broader sense the doctrine of assumption of risk may extend beyond contractual relations . In any event, when plaintiff has brought himself within the operation of the maxim, Volenti non fit injuria, he cannot recover. The doctrine discussed herein, by whatever name it may be designated, is said to rest on, or be in its nature, effect and import the equivalent at least of, the principle expressed by the maxim, Volenti non fit injuria, which is itself predicated on the theory of knowledge and appreciation of the danger and voluntary assent thereto. The mere encountering of a risk, does not, legally speaking, constitute assumption of risk; it is only when the risk exists in spite of the exercise of due care or when the risk results from negligence which is obvious that it is assumed by the person injured.” (Italics ours.) And see Gila Valley G. & N. R. Co. v. Hall, 232 U.S. 94, 34 Sup. Ct. 229, 58 L. Ed. 521; Landrum v. Roddy, 143 Neb. 934, 12 N.W. 2d 82, 149 A.L.R. 1041.
In Gover v. Central Vermont Ry. Co., 96 Vt. 208, 118 Atl. 874, the Supreme Court of Vermont says that since the maxim extends beyond contractual relations, the limitations of the doctrine of assumption of risk based thereon must be looked for in the terms of the maxim itself; that any other course would be illogical and the limitations could not escape being purely artificial; that, therefore, the doctrine of assumed risk, in an action between persons not having relations by contract, must be confined to cases where the plaintiff knew and appreciated the danger and put himself in the way of it of his own free will and as the result of an “intelligent choice”. • In support of this conclusion the court then observes: “In effect the English cases hold that mere knowledge of the risk does not necessarily involve consent to the risk, and that the maxim does not apply on the mere showing of knowledge of the danger, but only where the circumstances are such as warrant the inference that the plaintiff encountered the risk freely and voluntarily with full knowledge of the nature and extent thereof.

Lord Chancellor Halsburg expresses the opinion in Smith v. Baker that, in order to defeat a plaintiff’s right by the application of the maxim, when he would other
