THE VALUE OF PAVING.
Vast Loss Entailed Upon the Cite 9
Through Bad Streets.
Comparisons of the Cost of Transporta-

Neglected.

Many people can only be induced to
incur large expenses for street paving
by well-founded prospects of gain from

investment. Though it Is less desira-

these very practical considerations. it
may well be subjected to such tests of

therefore, draw for ten hours three
times as heavy a load on streets of the
first class as on those of the second
class, there must be an average saving
of two-thirdS in the cost of all trans
portation by means of animals and We

In other words. the city with well
paved streets will get at the same cost
three times as much service as one with
streets that are not we'll paved.
The possible gain from this in dollars
and cents is indicated by the statistics
of freight transportation. In the year

moved !Ol. .344, 43T tons of freight which
was probably hauled over roads or
streets at the points of loading and un-
loading the cars an average distance of
half a mile each way. As load weigh
ing ton cannot be transported a mile
by means of animals and vehicles for
less than 40 cents. which will be used
in this calculation as an average
charge, the street haulage of the
freight moved by the railroads of the
United States in 1890 must have
amounted To about $3.50. 537. .775. So 1t
will be assumed. however. at the risk
OF being much too liberal in tendency
to underestimate, that the average
street haul was only quarter of a
mile each way and that the cost was
