94 THE MONTHLY BULLETIN. 



The reduction of the percentage of material denied admittance into 

 the State while apparently trivial is highly important from an economic 

 standpoint, as it concerns a class of goods that are very generally dis- 

 tributed throughout the State — fruit trees and ornamental trees and 

 plants from Japan. A thorough systematic attempt to eliminate the 

 causes for rejection of this class of material at the source of origin vi^as 

 undertaken by the writer, working in conjunction with the Japanese 

 Consulate, at the end of last year's shipping season, and the far-reach- 

 ing value of this policy is already apparent in the improved condition 

 of the material that has arrived so far this season. 



The matter of horticultural products in the possession of passengers 

 and crews from fruit fly regions is the phase of the quarantine work 

 upon which every energy is bent. It is paramount to, and takes prece- 

 dence of all other inspection, and while but few of the parcels inter- 

 cepted and examined are found to contain hosts of the fruit flies, the 

 increase in receipts from this source is an index of the thoroughness 

 with which the same is pursued.
