The following is the order as issued by the State Commissioner of 

 Horticulture : 



QUARANTINE ORDER, NO. 4. 



Pertaining to the Melon Fly (Dacus cucurbitte). 



SACRAMENTO, March 28, 1910. 



WHEREAS, From information that has been received by this Commission, and the 

 fact having been duly determined by the Commission, it appears that a certain fruit 

 and vegetable fly known as Dacus cucurbita is prevalent in the Hawaiian Islands, 

 and very destructive to watermelons, muskmelons, cucumbers, and tomatoes on these 

 islands, and that the said Dacus cucurbita is not known to exist in the State of Cali- 

 fornia ; and 



WHEREAS, The introduction of this fly into the State would entail great and irrep- 

 arable losses to the horticultural products subject to its attacks ; and 



WHEREAS, The most rigid inspection can not determine the presence of the larva 

 maggot of this fly without the destruction of the fruit or vegetable which may be 

 infected ; therefore 



It is ordered, That a horticultural quarantine be, and is hereby established against 

 watermelons, muskmelons, cucumbers, and tomatoes imported from the Hawaiian 

 Islands or other territory known by the State Commission to contain infection of the 

 Dacus cucurbitce, and all deputies of the State Commission of Horticulture, County 

 Horticultural Commissions, and horticultural quarantine officers are hereby instructed 

 to hold all such fruits or vegetables above described for exportation out of the State 

 or to be destroyed, as may be directed by the owner or consignee. 



J. W. JEFFREY, 



State Commissioner of Horticulture. 

 Approved : 



J. N. GILLETT, 



Governor of the State of California. 



WARNING. 



After reading the facts herein presented, we can not see how any 

 patriotic, thinking citizen of California, or, for that matter, of any state 

 or country, could knowingly aid any condition or circumstance that 

 would possibly result in the introduction of this fly, either to this or any 

 other state. 



It is plain that shippers of fruit, and those directly or indirectly 

 interested in this industry, will not be guilty of in any way causing its 

 establishment. The danger, therefore, lies with the unacquainted, 

 unthinking traveling public, who, in making a pleasure trip to the 

 islands, or from the Orient, will bring in fruit to their friends, or for 

 their own use. 



It is undoubtedly your duty to spread information as to the real 

 danger that now exists to California's great fruit industry from such 

 unintentional carelessness. 



We, therefore, solicit the aid of all of those interested to join with us 

 in sounding at once a note of warning that may avert the catastrophe 

 which seems imminent.
