THE TEST.

cut the roadbed, but increase the bur
den of the horses.
Practical tests were made near At
lanta some months ago, and the illus

The bill prepared by Mr.. Heiskell is
as follows:
"A bill TO regulate the width of tires
on traffic vehicles.
Section l. Be it enacted by the
general assembly of the state OF Ten
nessee, that all traffic vehicles, without
rubber tires, shall be required to have
wheels of one-inch average width for
each 2%50-pound load capacity per wheel.
That is to say, a four-Wheeled vehicle
of 1000 pounds capacity shall have 11a-
inch tires; of 1000 pounds capacity
shall have tires of pa inches wide; OF
4,00O-pound load capacity, Az inches
wide; of 5,000-pound load capacity,
5A inches wide; 6,000-pound load ca
pacity, six inches wide; of 7,000-pound
load capacity, 612 inches wide; 5000
pound load capacity, seven inches
wide. All two-wheeled venlcles Of one
half the carrying capacity of the above
four-wheeled vehicles are to have
wheels with widths of the tires above,
respectively.
sec. >. Be it 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 $25 for each offense.
Sec. .. BE it further enacted, that
this act take effect six months aftei

"A very important point is that the
table OF test results of the Missouri
experiment station, relied IN by l. O.
Baker professor of civil engineering
University OF l%llinois) and others is
wrong in so far as it seems to support
!, an idea that wide wheels pull harder
Out Of "a conditions tested only three
have any appearance OF confirming
such erroneous notion. One of these
| three shows 35 per cent. disadvantage
Of good macadam road over bad earth
f road, and Go per cent. disadvantage
OF good earth road over bad earth
roads.
In discussing his measure MIR. Heis-
; Eell said that good roads are not pos
, sible with narrow tires. He said that
, his idea was that such a bill should
/ be passed as would not become a dead
letter by reason OF the fact that it was
Z, obnoxious to the people. The cost oil
roads and streets is divided into three
parts: The cost of making them lad;
Il the cost of bring them back to Their
o original condition-these should be cut
g out-and the cost of improvement upon
;, the original condition. This cost coulu
+ be cut down about hall. Wide tires
leave the roads in better condition
than before passing over, Narrow tires
0 have just the opposite effect. Mr.
e Heiskeli quotes many authorities Oh
it road building in support of this posi-
r. ton.
t, In the other two cases the show
d ing of any disadvantage from wide
6 siX-inch wheels, is due solely to nut
-
" made by the narrow 11a-inch tires.
