which need not bers b. discussed. The

Sered as yet. An attempt has been made
~ the writer during the present season to
determine approximately the eastern bor-
Ter Of the basin, rith ths following re-
suits:

A. to the Multiplication Of wells.
To the second query also, only partial
answer can be safely given. The multi
plying Of wells thus FAR has caused no

graphical survey, what the effect OF 1000

Of the water bearing strata. the character
Of the underlying beds, the location and
sxtent Of the collecting area, are all vital
facto,s in the problem and must be posi-
lively determined before q positive an.
swer can be given to the question, Is the
supply sufficient"
In answer to the third question it may
be said in general that there is compare
lively little of tho area included in the
Nartesian basin which cannot be reached
by the flow from the wells. Just what
the exceptions are will be known when a
careful survey Is made. 1t is quite evil
dent that the wells cannot be made TO
water the regions outside Of the area in
which they are found.
The Number Of Wells Needed.
In regard to the number OF wells that
would be needed the following figures are
One inch OF rainfall gives eco barrels to the
lcre.
One inch Of rainfall gives $50 lco barrels TO the
One inch Of rainfall gives 1854, 400 barrels to

The average annual rainfall Of the Mis-
souri, valley Is about 20 inches, probably q
little more in the region under discussion.

would require seven such wells in each
township, provided that ell the water ID

latter would be true. Nor is it believed
that il would be necessary to double the
present rainfall. One half that amount,
under control. would be ample.
