The census bureau has utilized the

tects. The population. white and col

wealth and Industrial development,
are all upon the map. The distrbu-
ton of the rural population to the
square mile, from the time Of the
first census in 1890 to the last IN
1910 is clearly portrayed by g ser
lies of twelve beautifully colored maps.

crop production, in amount and value,
as well as the extent and Increased
value OF all irrigated lands in every
state and county, are all to be found
upon the map. In manufactures, the
value Of the plants for all the lead
ing products, their production, itsI
quantity, value and the number OF per-
sons employed, find their place upon
the map. So does the amount OF
horse power for all classes of indus
tries, the hours of labor both by day
and by night, and many other condi-|
lions which are shown for the sepa-
rate states to permit comparison.
Maps aid research in many branch
es of sociology. The number OF mar
riages and divorces, theireper cent
q increase and the localities in which
they are most numerous, are dndicat-
ed by different shadings upon the
map, as are also the different reltg-
ious denominations, their average Of
church attendance, value of church
property and other details. A very
unique map recently printed to illus

source of the first 5000 appeals for
aid sent in to Mrs. p. H. Hartman
OF New York. They came from every
state in the union, but were SO mum
erous in the vicinity of New York
that larger space outside the map
had to be taken to represent that city.
Commercial Uses.
Commercial organizations utilize the
map to indicate the localities In.
which their commodities are in the
greatest demand. Automobile COM
panfes have the number of their ma
chimes sold in each county In the
country in order to know In which
direction it is most desirable to exert
special effort to promote business
Patent medicine dealers know by the
map what regions have the greatest
demand for their special offerings,
and In most cases do not waste much
effort in other trrHory.
The most important class of maps
prepared for commercial purposes,
because of their accuracy and the de-
tail contained, are those prepared for
the use of fire insurance companies.
Insurance maps have now been pre-
pared for every important city and
town in the country and for many
small villages. Nearly a quarter OF
million sheets of insurance maps
~ lcd in 10 NF1T1-
gressiona1 library where they can be
consulted at any time by anyone
wishing to know the IRE risks. and
the valuation of property in any To-
cality. When a large fire breaks out
| In any city the value of the property
destroyed can be ascertained by these
maps before any reports are In.
Newspapers rely absolutely upon
them, and their value is increasing
each year.
The publishers OF insurance maps
keep force of trained men constant
lly in the field collecting additional
material to be added to new editions.
The Insurance map craftsman will
make the first map upon base or
plot of the town secured through the
assessors Office or some other relia-I
BILE source. He will go over that
town. block by block, marking upon
each lot upon the map the conditions

ing to their fire risks. Wooden roofs
are designated and note is taken IL
their fire risk is increased by the
close proximity o. railroad or fac
tory likely to send sparks from its
chimney.
Factories and Industrial establish
ments are inspected and careful note
made upon the map regarding their
fire preventative precautions A firm
