PREFACE. 
Since assuming the duties of State Commissioner of Horticulture, 
October 20, 1911, there have come to this office many requests for litera- 
ture on citrus culture. We could not meet this desire, as the admirable 
work of the late Mr. B. M. Lelong, for years connected with this office, 
has long been out of print. This led to the writing of this little treatise. 
It seemed wise and well to prepare at once something to take the place 
of Lelong’s ‘‘ Culture of the Citrus in California’’ to send out in response 
to these requests, and hence this unpretentious booklet. 
I have purposely made this a manual; simple, brief, and severely 
practical. We might have gone thoroughly into the history of citrus 
culture, especially in our State, but the beginner or novice, for whom 
this is principally intended, usually cares little for that; we might have 
discussed varieties at length, but this would be confusing and not in 
accord with our purpose, and so we have considered this subject only so 
far as it is immediately practical. 
I am greatly indebted to Messrs. C. C. Teague, R. M. Teague, A. F. 
Call, C. C. Chapman, Dr. G. Harold Powell, Fred Reed, J. H. Reed, 
J. D. Culbertson, E. K. Koethen, R. P. Cundiff, aud especially the 
secretary of the commission, Mr. KE. O. Essig, and many others who have 
given valuable aid.
