MOUNTING MAPS. 77 



water with large blotters. Lay the map face down 

 upon the muslin, and with a wide flat brush (rubber 

 bound) apply paste quickly but evenly over the back of 

 the map. Turn over the map and press it smoothly 

 upon the muslin, using a blotter and roller. Leave it 

 to dry overnight. The hands should be wet when 

 handling a wet map and the surface of the map should 

 be rubbed as little as possible. It is better for two 

 persons to work together, holding all four corners of the 

 map and allowing it to fall upon the muslin from the 

 center toward the corners, thus avoiding air bubbles. 

 If any paste gets upon the face of the map it should be 

 immediately removed with a wet sponge. 



Three or four layers of maps may be mounted on the 

 same board, provided a dry piece of muslin (same size 

 as map) be placed between the layers. 



In some instances, for convenience in folding to 

 pocket or other small size, the map should be cut into 

 sections, all of the same size and shape, and mounted 

 with a slight break between each section, where the fold 

 will come. In this case, each small sheet must be 

 placed separately upon the big sheet of muslin, which 

 has been previously dampened slightly. 



One gallon of paste may be made as follows : Dissolve 

 1^ pounds of lump starch in 1 gallon of water. Then 

 stir constantly while pouring boiling water over it until 

 the mixture becomes thick. Set aside, and when almost 

 cold squeeze through a piece of cheesecloth in order to 

 remove the lumps.
