Des Moines, Aug. 6.-Bulletin "a, of
the state geological survey extended
mention of which was made some time
ago, will soon be ready for distribu-
ton, and Assistant State Geologist
Lees is today sending out information
as to it's contents for the benefit Of all
who may be interested in what is be-
lieved to be the most valuable of the
many bulletins issued from time to
time. The volume contains the dis
cussion of mineral production in Iowa
for 1911 and 1912, and also the re-
port on road and concrete materials
Of Iowa by S. w. Boyer and H. F..
Wright, and the analyses of Iowa Goals
by A. w. Hixson.
States Road Materials.
For several years S. w. Boyer, H. F.
Wright and assistants have been max
ing detailed investigation in the
field and in the laboratory of the road
and concrete materials of the state.
The laboratory tests were made at the
experiment station of Iowa State Col
lege. The report just issued is the re-
formation will be (of inestimable value
to the people of the state. There never
was a time when the people were more
interested than they now are in the
subject OF good roads. Only recently.
for the first time, has a highway COM
mission been created in this state.
There is reason to believe that under
the wise direction and supervision OF
efficient engineers the roads of Iowa
will soon compare favorably with the
best roads of; the other states of the
country Road Improvement and road
building depend largely upon the avail
ability of sand and gravel, clay, lime
stone, sandstone, glacial powders, and
the manufactured products of clay and
limestone. 1t is gratifying to know
that the investigations of DR.. Boyer
and his assistants have shown that the
majority of the counties Of Iowa are
amply supplied with materials suitable
for one or more types of road that are
believed to be practical under existing
conditions.
Coal Analyses.
The report on the analyses Of Iowa
Goals by A. w. Hixson will be of great
value to all persons who are interested
in the coal industry of Iowa. Among
the many features discussed there are
included the following:
/. Methods used in sampling coal
mines.
2. Descriptions of the mines sampled.
3. Details of methods used in maxi
ing proximate and ultimate analyses.
4. Proximate analyses Of sixteen
Iowa Goals.
5. Ultimate analyses Of sixteen Iowa
Goals.
6. Complete analyses Of the ash Of
sixteen Iowa Goals.
Z. Discussion of the physical and
chemical properties of each coal an
alyzed with suggestions for increasing
the value of the coal.
S. The Industrial value Of Iowa Goals
with special reference to their adapta-
bility for coal-gas and water-gas man.
ufacture and their utilization in pro-
ducer-gas plants. Methods are given
for improving their steaming values.
also suggestions concerning power
plant practice.
9. Comparison of Iowa Goals with
those of northern Illinois and Mis-
souri,.
10. Purchase of Iowa Goals under
specification.
