114 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE. 



Active control work was undertaken in northeastern Oregon in 

 the fall of 11)10, ami was completed June 30, 1911. This work was 

 done bv the Bureau of Entomology, in cooperation with the Forest 

 Service, with private owners, and with the General Land Office of 

 the Department of the Interior. The preliminary reports indicate 

 tlu\t 27,158 trees were treated at a cost of $33,180 to the Forest 

 Service, and that 6,8r)3 trees were treated at a cost of $2,806 to private 

 owners. More than 100 men were engaged in the work during May 

 and June. The results of this large control demonstration can not 

 be known until the close of the present fiscal year, but it is believed 

 that tliey will prove to be successful, and that the demonstration of 

 methods and the training of men for control work will be of the 

 greatest value in the future. 



It is estimated that the timber saved as the direct result of control 

 work in the Rocky Mountain region, under instructions from the 

 Bureau of Entomology or according to its recommendations, repre- 

 sents a stumpage value of $2,000,000. 



INSPECTION AVORK. 



In my last report I called attention to the urgent need of the pas- 

 sage by Congress of a plant quarantine and inspection law, and 

 showed that the Ignited States is the only gi'eat power without a law 

 to protect it from the introduction of plant diseases and insect pests. 

 Practically all of the European and other foreign powers have such 

 laws, as have also Canada and the other important English colonies. 

 The United States has become a dumping ground for refuse stock, 

 much of which comes to this country to be sold by auctioneers under 

 the hammer. The better class of nursery stock is also often infested 

 with insect pests or diseases which could be detected by proper 

 inspection. More than half of the important insect pests of the fruit 

 and farm products of this country were originally brought in on 

 imported nursery stock, and these now occasion an annual tax of sev- 

 eral hundred millions of dollars. The San Jose scale, the cotton boll 

 weevil, the gipsy moth, and the brown-tail moth are instances of 

 accidental importations, and the alfalfa weevil mentioned in a pre- 

 vious paragi-aph is another. Since my last report infested stock has 

 been constantly coming in. The Bureau of Entomology has been 

 notified by the customhouses and by tiie railroads when plants are 

 received, and such arrangements as could be made for inspection at 

 points of destination have been carried out. In most of the States 

 there are efficient inspection laws and efficient inspectors. To exem- 

 plify the danger of the present condition of affairs, during the past 

 year a careful inspection of the importations by the Department of 

 Agriculture showed that more than 20 different pests had been 

 brought to "Washington from foreign countries on plants. Of course
