INSECT PESTS IX FOREIGN LANDS. 



Third Progress Report by Mr. W. W. Froggatt, F.L.S. 



[Continued from fagc J 20, Yol. F.) 



Washington, D.C., U.S.A., 



13th October, 1907. 



I have the honour to forward a progress report ot my movements and 

 work since I left California on the 17th of September last. I found that 

 it would be quicker and cheaper to come straight across to Washington 

 than to come via Texas, as I had first proposed, particularly as I could 

 easily see the cotton weevil work on my road to Mexico. 



I arrived here on Sunda\ morning. 22nd September, and on Monday 

 went up to the Agricultural Department, where I presented my 

 credentials to Dr. L. O. Howard, Chief of the Staff, and had a long 

 talk with him about the most advantageous way of spending my time and 

 seeing the inner working of all the divisions and branches into which 

 the Department of Agriculture at Washington is divided. Through his 

 kindness. I have been enabled to go about and interview all the oflficers 

 and see the methods they adopt in breeding specimens, and in looking 

 after their specimens, books, and materials. 



There are over 10.000 persons in the Department of Agriculture at 

 Washington and scattered through the Federal offices in the United States ; 

 there are 300 in the Entomological Division, and in the Plant Pathology 

 and other groups of this di\'ision under Dr. Galloway there are seventy 

 botanists at work. Each of the leading entomologists under Dr. 

 Howard is a specialist on a certain group of insects ; thus — Dr. Hopkins 

 deals only with forest insects ; Professor Webster, with insects infesting 

 field crops; Marlatt. scale insects and the best methods of dealing with 

 them ; Quantance. with those on fruit-trees and truck crops ; and Banks, 

 with ticks and animal parasites, and .so on ; therefore, they can get 

 through a great deal of original work, besides answering correspondence. 

 Besides this, also under Dr. Howard, there is a large staff of workers 

 at the National Museum, each being in charge of a different group of 

 insects. W^ith all these officers 1 have spent some time, and thev have 

 been very kind in placing all their information at my disposal. One of 

 the greatest time-saving methods is the card catalogue svstem in all branches 

 of work, even extending it to the collections. 



I have specially inquired into the habits of all cosmopolitan .pests and 

 the methods adopted here and in other parts of the States, and the range 

 of the insects, but will not enlarge upon it in this report, as it would take 

 up too much of your time, but have recorded all my observations in ray 

 journal. The two species of fruit-flies found in the New England States 

 are not known in the west or southern States. Tryfeta pomonella is very 

 common in the State of New \^ork, and in some years damages as manv 

 apples as the codlin moth ; but the commercial orchards are of verv small 

 extent, and ven- little is done to keep it in check. The same might be 

 said of the cherrv fruit-flv {Trvpeta cingidata), which is common in cherries 

 in the same districts. The climatic conditions and the neglect of orchards 

 Avill not furnish us with any suggestions in our work of fruit-flv destruction. 

 I have met Mr. Gilles, in charge of silk-work culture, a business that the
