within the last few years, however,
the asphalt trade has been dominated
20 steadily increasing extent by a.
diRcrcnt variety Of asphalt obtained
by boiling down heavy petroleum
found in California sud In the region
OF the Gulf OF Mexico % semisolid
material which has found wide use for
roofing purposes and as a binder IN
modern road construction. A total Of
3as.aia short tons OF this oil asphalt
was made IT, 1912 and had value az

OF. This Is gain Of g3.1 per cent
over 1911, ana is nearly three times
as much as the output Of All other

shown IN the annual report by David

lcai survey. published as an advance
chapter from Mineral Resources for
1919.
Asphaliic oils differ very widely In
the proportion Of asphalt contained,
ranging from oils having no asphalt
90 very viscous oils which are suitable
for road material with practically no
refining. such natural liquid asphalt

near Lander. Wyo. II has not set
