eradication of Citrus Canker from Florida and other states of the 

 United States. The writer, who has been active in spreading this prop- 

 aganda, has predicated his arguments in support of the same on the 

 perhaps selfish grounds that so long as a case of this disease existed in 

 the United States it would always remain a source of potential danger 

 to the present clean citrus orchards of California. In support of this 

 theory we call the attention to every fruit grower in the State to the 

 photograph herewith reproduced. 



As the illustration clearly portrays, this is a box of Florida gro^^Ti 

 grapefruit in the original package, and the fruit infected with Plio- 

 mopsis citri still in the original wrappers. Note the ingenious method 

 employed to evade the regulations : Wrapped in many folds of brown 

 paper; placed in a regulation trade apple box; nature of the contents 

 "Northern Spy" plainly marked on the outside (as provided), and 

 billed through AYells Fargo Express Company as "one box apples" by 

 Pearson Ryan and Company, Portland, Oregon, to T. Pearson, San 

 Francisco. 



It would have been unction to our soul, as cpiarantine officers, to have 

 proceeded to the extreme in this case, but like many others diligent in 

 the service we have found the law — when you get the Simon-pure 

 article cold-drawn by a prospective prosecutor — takes cognizance of 

 many contingencies not apparent to a layman in the original language 

 of the statute. Hence in this instance we must content ourselves and 

 the service with giving publicity to those directly concerned in this 

 deliberate attempt to violate the horticultural quarantine regulations of 

 the State, and take comfort in the fact that while the will and the way 

 were present the end as conceived was prevented. 



BLIGHT-RESISTANT ROOTS— THE FIRST STEP TOWARD 



PEAR-BLIGHT CONTROL.* 



By A. L. WiSKERj Grass Valley. California. 



California's experience with pear-blight (Bacillus atnylovorus) dur- 

 ing the past two years has again emphasized the relative inability of 

 orchardists generally to control this most serious of all diseases to 

 which the pear is subject, and once more compels attention to the 

 imperative need of adopting every measure that tends toward its 

 suppression. 



When a single grower suffers a loss of $25,000 from blight in one 

 season argument is unnecessary to show that the situation is serious — 

 particularly in view of the fact that California's pear industry, accord- 

 ing to the last, census, produced more money than that of any other state 

 in the Union, notwithstanding the fact that her nearest rival. New York, 

 had 50 per cent more bearing trees, and in total number had just twice 

 as many as California. Michigan is close behind this state in number 

 of bearing trees and in total number, but the value of her crop was less
