been completed. The piece Of road
chosen for this purpose lies south Of
Townshend hall and is an extension Of
Neil avenue. It was the worst piece
of road on the campus, being built
largely Of cinders. All Of the coal for
the central heating plant Of the uni
versity has been hauled over this road
for several years; the coal used for
this purpose each year amounts to 10,-
900 tons and the hauling Is done with
three and four-horse teams, hauling
from Ave to seventeen loads.
One Of the chief objects Of the agri-
cultural department in building these
object lesson roads over the country
is to show the kind Of road which can
be built with the material to be found
In the vicinity In which the road is
built. Mr.. Jay F. Brown, special agent
of the ONCE Of public road inquiry, was
placed In charge Of the work on the
university campus. After q careful in
vestigation of the road material in the
vicinity Of Columbus, lie decided to
build the road Of crushed granite field
boulders. Most of the macadam roads
about Columbus have been built from
the Columbus limestone, which rs q
rather soft limestone and will not
stand the wear of heavy traffic. N the
summer 1t becomes dusty and In the
winter muddy, and ruts are soon cut
into such road.
The terms on which the government
cooperates in building these roads are
that the parties for whom the road II
built shall furnish the material anc
common labor, and the government,
furnishes the machinery and skilled
labor. The road on the university cam
pus was built as follows:
1t was excavated nine inches deer
and IS feet wide and the grade, which
was 7h per cent. in the steepest part
was cut to four per cent. It was ther
filled In four inches with broken briel
and stone from the remains Of thu
chemical building, which was burned
on the university campus last winter
