$2,500.00. Of course, the nozzles and 
sprays are included. They are quite ex¬ 
pensive. You will note Mr. Campbell 
says in his paper that he has a new nozzle 
that he thinks is going to work pretty 
well. 
Mr. -: I understand you to say 
you have 3-4 inch pipe over the trees? 
Mr. Gillette: Yes, sir. That seems to 
give service. Just as soon as we start 
the pump and turn those valves on, it 
looks like a fog. It is a solid mass of 
spray, and in ten minutes’ time the ground 
seems to be thoroughly wet, but, of course, 
it takes longer than that to put on water 
enough to do any good. I don’t really 
believe that it will take longer than from 
6 :oo o’clock until midnight to water the 
grove sufficiently, however. 
Mr. -: What is the estimated ca¬ 
pacity of the pump? 
Mr. Gillette: I have forgotten, exact¬ 
ly. I think it was guaranteed 7,500 gal¬ 
lons a minute and actual measurements 
showed I was getting over 10,000. 
Mr. Campbell: Hold on Mr. Gillette, 
Make that 750 gallons instead of 7,500. 
Mr. Gillette: All right, I guess it is 
750. That shows that some people here 
know what they are talking about, so far 
as the engineering proposition is concern¬ 
ed and I don’t pretend to but when it 
comes to knowing the results I want to 
obtain and whether or not I am obtaining 
them, I know pretty well what I am talk¬ 
ing about. 
With my system, it will be possible to 
water the whole forty acres in two nights, 
and I believe I had rather have a forty- 
acre grove irrigated this way, than 100 
acres without irrigation. 
J. P. Campbell. 
Mr. President , Ladies and Gentlemen : 
In the past I have had occasion to talk 
irrigation to several of you personally, 
and believe that I have done better by the 
subject that way than I will addressing 
you as a body, especially as I have had 
my time so fully taken up that it was 
only yesterday at the solicitation of 
Mir. Gillette, chairman of the Committee 
on Irrigation, that I decided to prepare 
this article. 
It is not my intention to attempt in this 
short space to discuss the subject of irri¬ 
gation from a technical standpoint, but 
will attempt briefly to cover some of the 
points most essential to the uninitiated 
who contemplate irrigation. 
Several years ago when I first became 
interested in the subject of irrigation it 
took hard work to find a farmer or fruit 
grower who would even take the time to 
talk about irrigation. The few plants that 
had been put in up to that time were most¬ 
ly improperly designed and constructed, 
and had not been successful, so the aver¬ 
age grower dismissed the subject as be¬ 
ing impossible or impractical. Now, a 
very different state of affairs exists and 
there are very few practical growers who 
do not realize the desirability, and most of 
them the actual necessity for irrigation
