ABSTRACT:
A table, having a removable transparent top with a box-shaped container directly below the top supported on legs which are removable and adjustable, is provided with a granular medium within the container and various measuring instruments associated there-with for creating or forming miniature simulated landscapes. The granular medium comprises a substance such as sawdust or a mixture of sawdust and soil or artificial soils lightly wetted by a substance such as oil so that the medium may be formed into shapes that retain their configuration until disturbed by outside forces. The measuring instruments associated with the table include both metric and English scales formed along the edge of the table, a miniature transit mountable on the table, compass, stadia and other surveying instruments.
