Some teachers prefer to commence the work of map-moldingby spreading a thin layer of sand over the board, and then out-lining the continent in the sand by means of a pointed stick orpencil. The excess of sand beyond the shore lines is thenbrushed carefully away, and the mountains and river basins lo- Advanced Work in Sand Modeling, 73. yi offL/\7K<T) ^\.^ Fig. 36. 74 Modeling from the Flat Layer of Sand. cated and modeled. A small sieve may be used in spreading theeven layer of sand, while common paint-brushes may be used intaking away the sand around the outline. Give the ingenious
