lHE COMPARATIVE TEST.


for the road. Marrow tires not only
cut the roadbed, but Increase the bur-
den of the horses.
Practical tests were made nsar At
lanta some months ago, and the illus
tration shows the result of same.
The bill prepared by Mr.. Heiskell IL
as follows:
"A bhl to regulate the width of tires
on traffic vehicles.
Section 1. Be It enacted by the
general assembly of the state OF Ten
nessee, that all trafic vehicles, without
rubber tires, shall be required to have
wheels of one-ineh average width for
each 2s0-pound load capacity per wheel.
That is to say, . four-wheelsd vehicle
Of 1000 pounds capacity shall have IN
inch tires; Of 1900 pounds capacity
shall have tires Of az inches wide; Of
4,OOO-pound load capacity, AZ inches
wide; OF 5.00O-pound load capacity,
6A inches wide; 6.O00-p0u load ca
pacity, six inches wide; Of 7,000-pound
load capacity, 6h inches widc; 5000
pound load capacity, seven inches
wide. All two-wheeled vehicles Of one
half the carrying capacity Of the above
four-wheeled vehicles are to have
wheels with widths of the tires above.
respectively.
"Sec. 2. Be 1t further provided, that
anyone violating the provisions of this
act by the use of tires Of width less
than herein required shall, upon con-
viction, be fined not less than S. and
not more than SIS for each offense.
''Ses. 8. Be 1t further enacted, that
this act take effect six months after
passage OF tho same"
In an interview, Mr.. Heislsell says:
"A very important point is that the
table OF test results Of the Missouri
experiment station, relied on by |. O.

wrong In SO far as 1t seems to support
an idea that wide wheels pull harder. ;
Out Of "a eondit4sns tested only three
have any appearance Of confirming
such erroneous notion. One Of these
three shows IS per cent. disadvantage
Of coed macadam road ever bad earth
road, and 6S per cent. disadvantage
Of COED earth read over bad earth
roads.
In discussing his measure Mr.. Has.
kell said that good roads are not DOS
sible with narrow tires. He said that
his idea was that such bill should
be passed - would not become q dead
letter BY reason Of the fsct that It was
obnoxious to the people. The cost Of
roads and streets Is DIVIDED int three
parts: The cost of making them bad:
the cost OF bring them back 70 their
original e0ndiMOn-these should be cut
out--and the cost Of Improvement upon
the original condition. This cost could
be cut down about half. Wide tires
leave tho reads In better condition
than before passing over. Marrow tires
have just the opposite effect. Mr..
Hetskel' quotes many authorities on
road building In support of this posi-
ton.
"In the other two cases the Show
ing Of any disadvantage from wide,
six-inch wheels, is due sslely TO mud
made Dy the narrow lh-insh tires.
Besides, and very much % at that.

show 20 per cent. greater pun for the
lh-inch tires; and 8 show so Der

II. IL and 1S shew 80 per cent. mere
pull on bad earth roads, and II and "a
show u per cent. more pull on farms.

inch tire, all other conditions being
equal.
Atlanta test Qf not the New York
three years experience az welD, plain.
ly shows that after abatement of the
ih-inch tires, which fixed conditions
of tests, the six-inch tires would have
pull in tests to 13. about 10 pounds
per ton Of load, whereas the narrow
wheels did pull about 40 pounds per
ton."
