“15. The survey records of 1892, 1895, 1904 and 1909 disclose that the ancestors of the plaintiffs held some of the frontier plots of Dubha Mal. The High Court was, therefore, asked to draw the inference that then ancestors held those plots during 1845 to 1863 when the Taufir land accreted. The question is whether such an inference should be drawn. Now, if a thing or a state of things is shown to exist, an inference of it continuity within a reasonably proximate time both forwards and backward may sometimes be drawn.

The presumption of continuity weakens with the
