All the conventional tints employed in geographical repre-sentation may be obtained from these, and their use will addgreatly to the beauty of the maps made. Of course the onlylimit is the artistic talent of the molder. It is understood that the maps from which the molds aremade must be perfectly dry and hard, otherwise the matrices can-not readily be made. MAPS OF FINEST FINISH. A simple extension of the processes given before will g\vQ amethod for production of rehef maps of a quality not surpassedin this country. Let a plaster mold be made as in the directionsgiven, and into this pour a thin layer of fine, smooth pulp, con-. Fig. of asia in plaster of paris. Paper Casts, 137 sistlng of macerated paper. This may then be backed by a thick,coarser pulp made of manilla, brown paper, etc. Another process which gives excellent results is as follows :Soak sheets of Whatmans best draughting paper in a size ofglue and paste.

Dry these layers by placing the mold in an oven ;then back the layers with pulp, or with plaster of Paris. Whenit is desirable to finish the map in water-colors, the first layershould be soaked in pure water, and the size or paste be appliedto one side only and after the sheet has been laid in the made in this way become very strong and durable, and arecapable of taking very h
