not had opportunity to carry them out. 
Those made a few years ago showed 
that the water went down six feet before 
meeting. It usually meets within a cou¬ 
ple of feet of the surface, but it does 
not make a great deal of difference wheth¬ 
er it meets or not. You can make it 
meet if you run a whole lot of water 
to thoroughly saturate the ground. 
Professor Rolfs: Then, it does not 
saturate the soil, as ordinarily used? 
Mr. Stanley: You can saturate the soil 
if you wish. You can put your furrows 
a foot apart. 
Mr. Felt: I have seen a furrow made 
and packed with a heavy roller, so that 
the water would run a long distance; 600 
to 800 feet. Of course, I do not think 
there was as much water running out at 
the end as what went into it. Of course, 
in that case it ran through the furrow 
and saturated the soil. 
Mr. D. C. Gillette: Has Mr. Stanley 
had opportunity to observe the new 
Campbell Automatic Sprinkler put on 
the market, and can he tell us whether 
it will reduce the cost of irrigation?' 
Mr. Stanley: I think you should ask 
Mr. Campbell about that. He can tell 
you about that. I have seen it several 
times. 
Mr. Hume: How many of them are 
supposed to be put on an acre? 
Mr. D. C. Gillette: They are, or 
should be, fifty feet apart. They cover, 
or have a spread, of twenty-six feet, I 
think, though I am not familiar with 
them. 
Mr. Peterkin: I was employed until 
a month ago with the Scott Lake grove, 
and I suppose I know as much about the 
sprinkler as anyone here; I was the one 
who had him put in one hundred acres 
under his irrigation system. The stand¬ 
pipes are fifty feet apart, and they throw 
a spray thirty feet from the standpipe; 
that is, they will cover sixty feet from 
edge to edge. 
Professor Rolfs: How much pres¬ 
sure? J 
Mr. Peterkin: Twenty pounds at the 
nozzle. They have an elevation of forty 
feet. The contract called for a hundred- 
horse-power engine to irrigate ten acres 
at a time. We had a final test and we 
had it running over twenty acres, having 
a perfect spread of water and giving a 
supply equal to a half-inch rainfall on 
twenty acres. This system, I think, is 
one that is not as costly as the overhead 
systems. It is cheaper than any other 
standpipe system, because it takes only 
seventeen sprinklers to the acre. I think 
it is going to revolutionize the overhead 
system, as it has been developed up to 
the present time. 
Mr. Thompson: I would like to say 
that I had a little experience with the 
flowing system of irrigation, and while 
we never attempted to run the water any 
great distance, only about 125 feet being 
as far as we have tried to run it at one 
time, we had quite good success,. I ex¬ 
plained our manner of irrigation in last 
year’s report. 
If we can make these furrows down 
which we expect to run the water some 
time in advance of the time we want to 
use them, so that they have a chance to 
dry out, the water will run over them very
