The above tabulation shows that
it takes less horse power to move
load over concrete than over other
types of road, which was determined
after extensive experiments carried
on by the California State Automo-
bile Association.
The experiment was carried on by
Prof. ]. B. Davidson, of the Agricul-
tural Division of the University of
California, and Austin B. Fletcher,
engineer of the California Highway
Commission, a national figure among
road builders and other prominent
road experts.
An appliance of the recording and
migrating type known as the Iowa
Dyonometer was used.
In order to insure absolute accur-
acy in these tests, the particular in
stiument employed was subjected to
careful inspection in the Engineering
Laboratory of the University of Cal
ifornia at Berkeley before being util-
lied.
The tests were held uniformly with
load of 5000 pounds gross, which
was made up Of a standard farm wa
gon loaded with California rice is
sacks. The motive powed used in the
tests at Davis was supplied by a fine
teamteam Of draft horses weighing
about 1900 pounds each, wagon and
horses being the property of the I'm
iversity of California. In the tests
made in the vicinity of Sacramento
standard two-ton truck, the proper
ty of the California Highway Com
mission, was used, through the cour-
tesy of Mr.. Austin B. Fletcher, High
way Engineer. So far as possible, all
conditions we've kept uniform except
road surface, the same wagon, the
same load, the same driver and the
same horses being employed and
practically the same speed being
maintained in the horse-drawn con-
tests, while the same man drove the
truck when it was utilized as motive
power, different speeds being record
ed as set forth by Professor Davidson
in his report.
Comparison between the lowest
pull recorded, that necessary to keep
the three-ton load moving, after it
was started, over the level, unsur-
faced concrete road, which amounted
to 83 pounds or 27.6 pounds per ton,
and the pull through stiff mud, which
was 654 pounds for the load, or 21S
pounds per ton, furnished ample food
for thought. Over the concrete road
the horses pulled together SO pounds
each horse pulling only 311a pounds,
while over the mud the team pulled
654 pounds and the pull on each horse
was 1927 pounds. The difference in
pull between the concrete road and
the mud road was 57l pounds, a diff
ference of 23t u pounds pull for each
horse, which is wasted energy, wasted
as absolutely as if it never had ex-
listed; and this energy, wasted day in
and day out, in the winter in every
part of almost every state in the
United States, is what is meant when
Bradstreet's Agency, with its fingers
on the business pulse of the Nation,
says: "Bank clearings Tin New York,
Chicago, or San Francisco) were af-
fected by the usual conditions"
