Map 3. DENSITY OF POPULATION IN 1903 
The population in 1916 was estimated to be one fourth greater than was as-

the designation of certain areas in the interior of northern Luzon one or two 
shades darker. The United States as a whole would barely fall into the class 
here shown by the middle of the five shades used.
