should be held in the absence of evidence on the subject; ” citing Nagle v. Allegheny Valley Railroad Company, 88 Pa. 35; Kehler v. Schwenk, 144 Pa. 348. The incapacity of a child under seven years of age to appreciate and avoid danger is conclusively presumed. Between seven and fourteen years there is a prima facie presumption of incapacity, but capacity, may be shown by evidence, positive or circumstantial.
