that have attained their full growth, they may leave the packages and 

 pupate in the crevices of this locker. Look at the open grating. "What 

 better opportunity for escape would an adult want than through the 

 openings between those slats. Compere is exceedingl}^ wise in the ways of 

 fruit flies, and this particular locker is his pet aversion. While we have 

 not as yet found the real article, we always manage to find reasons why 

 this locker should be thoroughly scalded. 



Cocoanut Sacks. 



This is part of a shipment of 2,000 sacks of cocoanuts from Rarotonga. 

 There are several species of fruit flies at work on the island, and all fruit 

 from that country is barred out under the provisions of section No. 5 of 

 the horticultural quarantine law. In this shipment the inspectors found 

 some nuts that were infested with maggots. A study of these larvae soon 

 showed that they did not belong in the family Trypetidm, but we take no 

 chances on any maggots found working in fruit, and while it was 

 accepted at the time that they were perhaps a result rather than a cause, 

 the shipment was held up. The consignees proved to us that they were 

 prepared to steam the contents of these sacks at high pressure, and with 

 the proviso that they do this together with the sacks, under the super- 

 vision of a quarantine officer, the shipment was released. This steaming 

 "was done in a retort wnth live steam under sixty pounds pressure to the 

 square inch for an exposure of forty minutes. 



steamed Sacks. 



I have shown you this picture just to verify the statement that these 

 2,000 sacks were steamed. Here you see them just as they were on San- 

 some street drying, and the dry ones being baled. I wish it were possible 

 to subject each individual thing that arrives in San Francisco from fruit 

 fly countries to a pressure of sixty pounds of live steam for an exposure 

 •of forty minutes. I sure would sleep much sounder. 



Railroad Work. 



It must not be supposed from all that has gone before, that the duties 

 •of the quarantine officers are solely concerned with imports arriving by 

 sea. On the contrary our record for the past year shows that the San 

 Francisco division has handled 298,763 parcels of horticultural material 

 that has entered the limits of our local jurisdiction by rail. Here is a 

 sample of this work on the screen — three carloads of plants and trees 

 from Holland via New York. I will not weary you with any detailed 

 description of this phase of the work further than to assure you that, as 

 you can see, each individual tree or plant is separately examined. 



Record. 



This is a page taken from our daily record and reproduced here to 

 show you how account is kept of each transaction, and also who is respon- 

 sible for the action taken in each individual case. At the bottom here 

 you see the item, "resacked and old sacks sent to the incinerator to be 

 burned." Compere and I have found the pupge of the Mediterranean
