Irrigation 
F. W. Stanley, Irrigation Engineer. 
Although there seems to be no official 
place on this society’s program this year 
for the consideration of irrigation prob¬ 
lems, I am very glad to have the 
privilege of addressing this body on the 
subject. I admit that I have talked before 
many of you for several successive years, 
and have usually discussed the subject in 
somewhat the same manner. Yet a 
recent trip along the lower East Coast 
has led me to believe that irrigation is 
still a very pressing problem and that 
there are probably a number of men here 
today who have not heard me before. On 
this account I hope that you who have 
had to listen to me so often before will be 
very patient for a few moments, for I 
promise you I will be brief. I would like 
to say in this connection, however, that 
this society has been of great help in the 
work which the irrigation office of the 
Department of Agriculture has done in 
this state, both in gathering new data 
and in becoming acquainted with men 
who do things. For instance, about 400 
acres of grove irrigation has been instal¬ 
led the last three years, or is under con¬ 
struction, which has been put in from 
plans submitted by our office. These 
men have done most excellent work and I 
can say the plants have been successful 
in all cases. All these irrigation plants 
use vitrified clay pipe for distributing 
water through the grove. Many of the 
members of this society have received a 
recent bulletin from our office entitled 
“Irrigation in Florida” which goes into 
considerable detail on this style of con¬ 
struction. 
But I am here to speak of particular 
problems that are present on the East 
Coast. These problems have not been 
treated in detail in the bulletin mentioned 
above, nor discussed before this society. 
The problems are: 
1st. Irrigation of the rocky limestone 
grove lands that lie between the ocean and 
the glades. 
2nd. Irrigation of the muck lands that 
lie at the edge of or within the glades. 
3rd. The irrigation of the sandy lands 
in most cases adjacent to the glades. 
The irrigation of groves (either avo¬ 
cado or citrus, and the irrigation of avo¬ 
cado groves is assuming importance) 
that lie on the rocky lands cannot be ir¬ 
rigated by the ordinary furrow or flood¬ 
ing methods. Yet this type of soil pre¬ 
sents no particular difficulty to the 
ordinary low-pressure irrigation system 
that is used in central Florida, if porta¬ 
ble or conductor pipe is used to carry 
water to the individual tree. Probably 
the best way to illustrate this point is to 
give a brief description of a grove re¬ 
cently surveyed for irrigation near
