THE MONTHLY BULLETIN. 545 



a result of the lamentable lack of literature on one of our most impor- 

 tant crops, California Citrus Culture, by yourself, was published in 

 1913. The edition of 3,000 copies is now almost exhausted. There 

 have been repeated requests from other states for this book, which we 

 have been unable to comply with, owing to the demand in this State. 

 This bulletin gives briefly, yet in sufficient detail to make the orchardist 

 familiar with each essential, the early history of, and the localities 

 adapted to, citrus culture in California, climatic conditions affecting 

 citrus trees, frost protection, planting the orchard, propagation, fer- 

 tilization, irrigation, pruning, cultivation, implements for the citrus 

 orchard, picking the fruit, packing, grading, insects and plant diseases 

 of the citrus tree, with methods of control, including fumigation, species 

 and varieties, by-products, and various state organizations dealing with 

 the citrus industry. 



Another bulletin which met with instant approval was the first 

 edition of Injurious and Beneficial Insects of California, by Mr. E. O. 

 Essig, formerly Secretary of the Commission. This was published as 

 the January and February numbers of the Monthly Bulletin in 1913. 

 The edition of 5,000 copies was soon exhausted, and in order to comply 

 with the thousands of requests for this book, a second edition of 5,000 

 copies was issued in 1915 as a supplement to the Monthly Bulletin. 

 The general scope of the second edition is practically the same as the 

 first, although many insects of minor importance have been included, 

 because of the demands upon the Commission's office concerning them. 

 This work is intended for the fruit growers of the State, and technical 

 terms, so far as possible, are avoided. The bulletin contains a list of 

 the principal destructive insects of California, with descriptions, life 

 histories, means of control, the principal beneficial insects found in 

 California, a chapter on sprays and poisons used in combating insect 

 pests, a chapter on fumigation, one on collecting and preserving insects, 

 a general index and a host index, under which the pests attacking each 

 species of plant are listed. 



Another valuable bulletin published by the State Commission of 

 Horticulture early in 1915, which has had a large call from the State's 

 apple orchardists, is Apple Growing in California, by Mr. Geo. P. 

 Weldon. Twenty-five hundred copies were printed, and to date we 

 have had approximately 3,000 requests for the book, not only from 

 California but from all parts of the United States. This bulletin is a 

 practical work, designed to cover some of the important phases of apple 

 culture in California. Statistics on the apple, varieties, propagation, 

 selection and care of trees for planting, care of the young trees, 

 pruning, top-working, intercropping, cultivation, fertilizing, thinning, 

 frost protection, spraying, insects and fungous diseases attacking the 

 apple, picking, grading and packing, by-products, insecticides and 

 fungicides, are all treated in a comprehensive manner. 



Other publications, most of which were printed in the Monthly Bul- 

 letin, and also as separates, for which there has been a great demand 

 are in part as follows: Alfalfa Culture, by yourself; the English 

 Walnut, by Frank E. Kellogg; articles on the Apricot, by J. C. Shiir^ 

 and R. E. Harrington ; Pear Culture, by Professor P. J. 'Gara ; The 

 Future of the Olive in California, by B. B. Meek; Olive Culture, by
