ConditIors Under Which They Can Be
Used to lsdvanaagn.
& prominent manufacturing concern
has instituted series Of experiments
lately, to find out the conditions under
which the broad and narrow tired
wheels could be used to advantage. In
the experiment to ascertain the differ
ence In draft between wide and narrow
tire upon grass sod, the figures arrived
at were:
yYcight OF wagon and locd. ........ 1880 pounds
Lrlit to 1t TT 10 WITH f]a-in' Ii

Draft TO STAR 1o1d with 3-inch tire
on bard roads 700 pounds
hard Toa1s ................. $50 pounds
Draft ct dead lull on hard pave
mcnt neutrality-suspicious.. les pounds
Another experiment was with four
inch and one and one-haf inch tires re-
spectiVcly on block pavement, good,
hard, sandy road, good, level, gravel
road, and in each soft and deep mud.
The conclusions arrived at by the
committee were:
1. On hard roads, block pavements
and other permanent and substantial
roads there is no argument, so far as
actual draft Is concerned, in favor Of
the wide tire, the effect being rather
against the wide tire.
2. In their effect upon hard roads the
wide tires have the advantage, and that
this benefit is not sufficiently appre-
ciated by turnpike and macadam road
companies.
g. In soft mud, slush, and under sim
flar circumstances, under which even
the wide tire cuts In, the advantage is
against the wide tire and in favor of
the narrow.
4. On soft sod and soft ground, where
the wide tire does not cut in and the
marrow does, the advantage is on the
side of the wide tire.
s. tn loading a team a draft of $50
pounds steadily applied is as much as
should be expected fer days work,
and that ON soft sod this may mean,
when dead-pull has to be taken, an
Increase n..the draft of 1000 pounds.
6. The difference in the latter case
between the regular draft of CSC
pounds and the increase of 1000 pounds
is equivalent to an addition of two
tons $50 pounds to the load.
z. Or, in other words, the draft OF
the load being CSC pounds may be con
sidered ns equivalent to a lead of two
tons $50 pounds. and the difference
from the steady draft of the load in
fair motion, and that of the same load
started at a dcad-puIl. is equivalent tc
doubling the load.
The committee c'csed their report
with: We advocate wide tire fol
farms, and narrow tire Tor good roads
and pavements.
Experiments at TIE ITtah expert
ment station demonstrated that a
given load on ~ inch tire drew Ale
per cent. heavier than when on g.
inch tire. the draft being on fairly
stiff grass sod; On n moist but hard
road the * inch tire drew 1877 pei
cent. heavier than the 3-inch.
An authority upon the subject of the
effect Of wi &c tire says: in New
York state The experiment was made
Of using W c tires On o road about
niles lon; - ing to a stone quarry
The hcav,5 WAGONS used thereon were
equipped Ulth rear wheels having
