Abstract
Abstract A device for displaying topographical features containing a terrain of a kneadable mass, the employment of a mixture of sawdust particles and and evaporation resistant liquid for said kneadable mass, in combination with means including chain-like parts for representation further elongated topographical features on said terrain, and a substantially rectangular casing of artificial material including integrally a bottom, vertical sidewalls and a horizontal flange affixed to the upper rim of said side-walls for supporting a cover-plate, at least the latter being of transparent material, for encasing said terrain of kneadable mass and said means.
