The paving question is one that con-
Germs the entire people OF this city Of
course as certain sections are favored
with the Improvement and the proper

city Council is necessarily engaged in
planning particularly for the work and
the contracts But we are considering
Just now, the subject Of street paving
in general and as It affects the general
public
We have already drawn attention TO
the ACCESSIBILITY OF a thorough invcsti-
CATION into the alleged opportunities
offered, by economic plans and home
material. TO reduce largely the expense
attending the paving Of our broad
streets and OF thus extending It's bene.

in this direction we understand, have
been taken by the city authorities and
we urge that these be followed up until

To this we here append the statement
OF Henry Rivers Ellis. Of this city, am

gist. as to the sample from those mines

paving material and adds
ut might be well to state briefly
what the constituents Of asphalt are.
Asphalt Is essentially a mixture OF two
substances, petroleno and asphaltcue
The petrolene h the soft sticky mater

ing property 20 asphalt and the as-
phaltlne is the solid hard portion
which gives It body,
An asphalt pavement containing too
much petrolene becomes ON warm days
soft and sticky, and on the other hand
II the pavement contain too much as
phaltene, Il viii he too hard, and win
crack and disntegrate
Judging from the physical properties
OF your material I win say that ! be-

"A good fault, as the material may be-
