INTRODUCTION. 
THE writer has recently completed a relief map of California 
on. a scale of I inch to,12 miles, and a vertical scale of I inch 
to 12,000 feet. This makes it about 4 by 5 feet square, and the 
highest peaks nearly 1% inches high. 
The accompanying plate was taken from a photograph of 
this map, and illustrates the main topographic features of the 
state. To give some idea of the accuracy of the topography as 
shown, the method of making the map is given. 
Method of making the relief map.—As no topographic map of 
the state was available, all the maps, levels, and other topographic 
data were collected and a contour map of the state compiled.
