Professor Campbell explained his sys-

more persons who gathered there to
form the Colorado Association for Sci
entific Farming, with view to adopt.

development Of the arid lands.

good many years." said Professor
Campbell. Some have asked me how
l happened to commence it. You have
the old adage that Necessity IL the
mother of invention haven't you?
Well. that's where l was. started
in the Dakotas in '79. The first three
years were simply ideal; harvested
my third crop in 'S2 and obtained over
10000 bushels Of wheat from 300 acres

thought l had struck the garden spot
of this great country; but the very
next year right on top of this enor

and it was here I began.

acres each on a quarter section when

a little snow. In the spring, the
moisture percolated into the soil and
We had one quite early rain. The first
thing did in the spring was to finish
plowing these lands, following with a
harrow. The result was that the two
lands that we plowed in the spring

few others there had the same re-
suits. What was our conclusions?
That spring plowing was the thing.
Now you see how easily we can be de-
ceived. Fall blowing would not do;
it was demonstrated to us; so the next
year we placed quite portion of 1t
under plow in the spring, only to find
that fall plowing gave us crop and
spring plowing nothing. This was my
experience for seven or eight years
before discovered a single fundamen-
tai principle by which l could do the
same thing and get the same result.
Nov we frequently see in print
the Campbell System We frequently
hear people say they know what it is.

thought I had solved the whole thing,
only to find on top of that that surface
cultivator YOU hear SO much about is
a great thing. Then l conceived the
idea of drilling with the rows twenty
inches apart and cultivating. l built a
machine which was success. Sixty
two were built next year and put on
the market. In '96 in North Dakota
We raised twenty-five and one-half
bushels of wheat, tifty-six bushels of
barley, and ninety-two bushels of oats;
but we soon discovered a difficulty.
We had to be so extremely careful in
so that we would not in
jure the crop.
I'VE finally dropped into the idea of
summer tilling. Begin in the spring
early by double disking. Let me illus
trate as to what the loosening up of
the soil may mean. Down in Texas in
the Panhandle district, where we are
working this year, we had four weeks
of dry weather. The fields adjoining
ours had no moisture whatever, while
our field was very moist clear down to
four feet and two inches. When the
surface is loosened up, the water can
go In and as soon as it comes in con
tact with the moist soil below, goes i'm
down. This is Illustrated in
a plant. When you turn the
water on it, at first it does not seem TO
percolate at all, but it soon works its
way down in, and all disappears;
comes into contact with moist soil and
goes to the bottom.
Another feature which seems to me
extremely wonderful is the fact that
we lose no water by percolation. Ma
ture seems to have provided that this
great stretch Of country here where We
get normal rainfall should not let the
water go on down in, but after it
reaches the bottom. it begins to work
its way up again. When we have had
moisture down say three to four feet,
and had four to six weeks without rain.
there is no variation in the depth of
the moist soil to exceed two inches in
all that time.
eve have attempted to show you We
can store the water in the soil. We
have made the statement that it will
come back. Now comes the question
of handling that top seven or eight
inches of soil in such way as to hold
the moisture in the ground so that it
can be used during a long dry spell
when We can get no rain. This is the
thing that has played the mischief. We
