Building Stone Distribution: "Distribution of the various kinds of building stone and the localities where the different varieties of stone are now being quarried or may be quarried in the future for Delaware are Marble and gneiss."

Granite: "In 1907 there were six States with an output valued at over $1,000,000. In 1908 Maryland dropped below $1,000,000, and Maine exchanged places with Massachusetts, although the production was almost identical for the two States."

"Of the other States, Colorado, Delaware, Hawaii, Missouri, New Jersey, New York, Oregon, South Carolina, and Texas increased in value of output, and Arizona, Arkansas, Idaho, Montana, New Mexico, Oklahoma, Pennsylvania, Utah, and Virginia decreased. Arizona, Colorado, Hawaii, Oregon, Utah, and Washington include some basalt and volcanic rock, and trappean rocks in their production; other States, notably Delaware, Georgia, Maryland, Pennsylvania, and Virginia, include some gneiss, trap rock, syenite, mica schist, diabase, etc."
