Attending Annual Conventions Of
County Officers.

Of the county officials Of the state will
make Council Bluffs their camping
ground this week. The annual conven-
tons Of four organizations-the super
visors. tho auditors. the treasurers, and
the stewards Of county homes-com-
menced here today, and continue for
three days.
From the fact that a number Of new
laws affecting county officials were
passed by the last legislature. the at
tendance this year will probably be
unusually large. A large part Of the
discussion mapped out for the convsn-
tons will consist of consideration Of
these new measures.
Discuss New Road Laws.
This will be especially true with the
supervisors. The new road law estab-
fishing system ID. permanent high
ways has kept most Of the county
fathers guessing, and from the fact
that the state highway commissioners
and engineers will be here to talk
things oyer q large number Of super
visors Will be here.
Because Of the great interest in the
new highway. law the supervisory con-
vention will probably be the most in
teresting Of the quartet. It is estimated
that 200 supervisors. representing prac-
tically all of the ninety mine counties
of the state, will attend this meeting.
Each Of the other conventions will draw
between twenty-five and fifty delegates.
Building Manawa Road.
Another interesting feature Of the
convention will be the road building
demonstration on the Manawa road
near the city. A half mile or more Of
highway will be built with the aid Of
the most improved road machinery. The
supervisors and others who are inter-
ested may visit the scene Of the demon
stration without difficulty, as It is
closely adjacent to the street car line.
Government Road Exhibit.
Thirteen exhibits Of model roads, H.
Illustrating the method Of using many
different road materials, were placed
on exhibition in the Merriam building
at 203 Pearl street Tuesday by repre-
sentatives of the federal Office Of pub
lie roads. The exhibit will remain here
thruout the supervisors convention.
Every form Of road material. includ-
ing asphalt. brick, concrete and the
various mixtures containing these sub
stances. is included in the exhibit. Not
only Is the surface material shown. but
each model also shows the most ap-
proved foundations and substructures
for the different materials.

htbit. Mr.. Eldridge has made q thor

more. value to city officials as it is to

road material used on the city streets.
together with the proper methods of
construction. are shown. Visiting city
and town officials. as well as the SUI
pervisors. are urged. by Mr.. Eldridge,
to visit the exhibit.
Three Kinds Of Concrete Pavina,
Three types Of concrete paving are
shown among the exhibits. In view Of
the fact that concrete paving is COM
ing more and more into vogue, and Of
the agitation for concrete paving in
this city. the exhibit will be especially
interesting to officials.
One form OF concrete paving employs
only concrete, another uses cement and
oil mixture, and the third has a con-
crete base with asphalt coating. The
paving substructure is also shown.
The great difficulty with using con-
crete as q paving material lies in its
elasticity" Mr.. Eldridge stated Tues
day forenoon. Concrete is easily at
fected by heat and cold, expanding and
contracting with every change in the
weather. Because Of this fact it is
necessary to provide extension rods at
frequent intervals to allow for the fire.
quent changes.
Must BE Laid Properly.
Even in laying the extension rods in
concrete. many serious mistakes have
been made. Sometimes, when a felt
mixture is used, the concrete settles.
and Is easily broken by traffic. AS
whole, concrete paving IN not entirely
satisfactory. due to the fact that it is
Yet In an experimental STAGE.
AS to that. tho" Mr. Eldridge con-
tinued. "all forms Of road work might
be considered in an experimental stage.
It has only been within recent years
that there has been concerted move
mont to secure durable. permanent
highways. and II was not until this
agitation was well under way that
systematic study was made Of road
building"
The exhibit on display here is usual
ly housed at Washington. and 10 only
taken out for expeditions. good roads
meetings, dsmonstzatien trains and the
like. When an exposition is national
in character. the government usually
make an appropriation to cover the ex-
penses Of moving the exhibits.
