Evans constructed several geological models or relief maps, his method being to paste layer upon layer of cartridge paper so as to secure the necessary elevations, and then to colour the whole according to the outcrop of the rocks. His models of the valley of the Thames near London, of a part of the same on a larger scale, and one of the whole of England, were passed to H. J. Lister of Eldon Road, Hampstead after Evans' death; a map or model of the country round Hastings is in the possession of the corporation of that town; he also constructed a model of the neighbourhood of Sidmouth. Evans's extensive collections of fossils were purchased by Mr. Ernest Westlake of Fordingbridge.
