A Timely Bulletin. — rrofessor II. S. Fawcett has placod us under 

 renewed obligation to liiin in ])r(>i);ii'injj^ Unlletin No. 2f)2, University 

 of California. This l)roehure eonipares eitrus troubles — fungoid. l)ac- 

 terial, pliysiological and insect ravages of citrus trees — in California 

 with those of Florida, Cuba and Isle of Pines. We are pleased to 

 note that we are free of many serious ills that our Gulf coast neigh- 

 bors are called on to fight. No doubt, our efficient (piarantinc service 

 is largely responsible for this happy riddance. Our strict quarantine 

 has doubtless s.aved us from stem-end rot, another stage of ]\Ielanose, 

 which Professor Fawcett declares to be the most common and trouble- 

 some rot of citrus fruit in Florida next to blue and green mould. In 

 speaking of eitrus canker the statement is made that it is by far the 

 worst disease that has ever yet affected the citrus industry. We are 

 interested to learn that this scourge is bacterial rather than fungous, 

 as has generally been claimed. 



The bulletin contains on the closing pages very instructive tables 

 comparing insects and diseases on citrus trees in California, Florida, 

 and Cuba, respectively. We summarize as follows: 



CITRUS INSECT PESTS OF CALIFORNIA, FLORIDA, AND CUBA. 



DISEASES OF CITRUS TREES IN CALIFORNIA, FLORIDA, AND CUBA. 



Total diseases not found in California, 22. 



These tables emphasize strikingly the need of a Avell equipped and 

 efficient ciuarantine service. — A. J. C.

 of Agriculture, (m the dispersion of gypsy moth larva? or caterpillars 

 by wind, some surprising facts are recorded. Tanglefoot traps were
