lcrl soil samples for analysis llr
has the 0lkali instrument used Go
show how much alkali Is in the su,l
| other pictures IN the same frame
SHOW the different steps of making
the analysis,
Another frame shows how soil slr-
/ Nrls are made. The work of BORING
ont soil samples, Of collecting them
Tor laboratory analyses, ana of MAX
ins the plane table may of the re-
gion Is shown IN four pictures.
Another set OF pictures shows the
/ collection of 10000 soil samples
| which has been collected by IA, bu-
| Iouu of soils from all parts of the
/ United states These samples are
| used for analysis and kept 80 that
| soils sent 10 the bureau from any
| part of the country may be CONE
] pared with the samples already
/ studied, I'm this way any sample scnt
to the bureau can bee matched up with
soils which have already been studied
and everything which has been found
| out concerning the soil sample can
be placed at the disposal of the far
mer who inquiries about his own soil
A large case IN the bureau OF soils
exhibit shows 10 different soils and
| subsoils which have been collected
| from the dry-laud farming regions
| from the Canadian line to the Rio
/ Graude, Soil surveys have been made
| covering all OF the western portions
Of North Dakota, South Dakota, KAN
| sas and Nebraska, and all of the Pan
handle country of Texas. Copies of
these soil surveys are displayed on the
back of the SOIL sample cases.
Another case Of samples displays
all Of the minerals which are COM
monty found in the soils. over thirty
/ different minerals are shown and
from these the potash, phosphoric
acid and lime which constitutes the
/ plant food found in the soil are de
/ rived In this same case there are
| also shown the common materials
| from which commercial fertilizers are
manufactured. These include the
phosphate rock of Florida, Tennessee
aud Wyoming The tankage and dried
blood supplied by the slaughter
houses, the cotton seed meal from the
oil mills and the potash salts from the
German mines.
The different steps in making a
soil map are fully shown in a series
| Of illustrations in the large frame at
| the front Of the booth The work
Of making base map begins with the
| pencil outline and is followed by the
! different steps of mapping the roads,
| houses, streams and towns. Upon
| this base map the soil surveyors show
IN different COlors the location and
| the extent of all of the soils I'm any
county where the work in being car
/ ried ON. other portions Of the same
display show how the field map is
sent to the office Of the bureau of
soils to be adjusted and drawn in
| ink and water colors before it is sent
! TO the engrayer. Then the different
steps Of engraving the map are also
shown and the completed map Sc
| cured by all these processes is shown
at the bottom Of the frame
Soil surveys have now been made
| In portions Of every state in the
/ United States. In fact, nearly one
| fifth Of the entire agricultural area
of the country has been mapped Ia
detail, while reconnaissance soil sur
| veys have shown the different kinds
Of soil and the crops TO which each
! is adapted I'm nearly One-haf the
! dry land farming district.
A list Of these soil surveys is be
| ing distributed at the exhibit so that
those who are interested may write
to the bureau Of soils at Washington,
y. c., to secure copies of the maps
and reports on areas which would be
of interest TO different individuals.
Other publications on soil fertility
alkali lands and methods of soil man
agoment for the dry-laud region are
also given to the farmers who may
wish them.
The exhibit is in charge Of Dr. j.
A. Bunstcel and Mr. r. +. Cummings
II the bureau Of soils, who give dem
onstratons Of the soil analysis work
and explain the different features of
the exhibit to all who are inter
