484 Journal of Agricultme. [10 Aug., 1908. 



called upon Mr. Middleton, in charge of the experimental work of the 

 Board of Agriculture at Whitehall Place, who, with Mr. Rogers of the 

 Intelligence Branch, gave me some information as to their methods of 

 administration and carrying out of experiments. 



I was able to attend the monthly meetuig of the Entomological Society 

 of London, where I gave the members a short address, at the President s 

 request, on our Economic work in Australia, and met many of the leading 

 entomologists of Great Britam. I also attended the monthly meeting of 

 the Linnean Society of London at Burlington House. Having been four 

 weeks in England, and gone through most of the important economic 

 collections, I left for France on the loth March and reached Paris the 

 same evening. I engaged an interpreter, and next morning called upon 

 Professor Marchell at the Department of Agriculture, and with him 1 

 spent three days, first going through his collections and noting his methods 

 of work, and then in various institutions. At the Jardin de Plantes I 

 found the Natural History Museum very beautifully arranged for the 

 public, the nests of insects being particularly fine. I went through the 

 cabinets of Diptera and other specimens. Professor Marchell informed 

 me that the Mediterranean fruit fly has, on several occasions, been taken 

 in the orchards near Paris, but it has never become established and has 

 probably been brought in the larval state with imported fruit. The olive 

 fly {Dacus olece) is common in several districts in the south of France, but 

 has never become a serious pest, and they have no vegetation diseases law 

 to deal with anvthing but phylloxera. I met the professor at the Pasteur 

 Institute, which has charge of the specimens dealing with the tropical 

 diseases, and I attended a meeting of the Doctors dealing with " Sleeping 

 Sickness," upon which they are carrying out many investigations. I was 

 also fortunate in attending the monthly meeting of the members of the 

 Entomological Societv of France, and there spoke on our work in, Aus- 

 tralia, my remarks being translated into Franch by Professor Picet. At 

 Professor Blanchard's lalioratories I met Dr. E. Brumpt, who has worked 

 on biology in Central Africa, and is now investigating the Fowl ticks and 

 their methods of transmitting diseases. At the College of France I met 

 Dr. Felix Henneguy, who had dohe a great deal of fine work on the 

 morphiology of insects. With Professor Marchell I went through the 

 Experimental Gardens at the Luxembourg, and also to Professor Griffon's 

 laboratories and experimental grounds, he being Vegetable Pathologist to 

 the Department of Agriculture and Director of the Grenoble Station. 



On the 13th March I left for Madrid and reached there on the follow- 

 ing day. I first went to the Mu.seum of Natural Sciences, where I 

 examined the collections and met Dr. Boliver, the Director, who said 

 they had plenty of specimens of olive fly, but none of the Mediterranean 

 fruit fly, though it was at times a pest in the south of Spain. I visited 

 the Agricultural Experiment Station and College where the Director, 

 Profesor Navarro, gave me a great deal of information about the insect 

 pests in Spain, and advised me to go to Valencia to see the orange orchards. 

 I inquired about Mr. Compere's statement that has been so widely circulated 

 through the newspapers, " that there was no codlin moth pest in Spain on 

 account of the parasite he discovered there destroying them." Professor 

 Navarro said, " That from his own observation he knew there was 

 hardly an apple grown in Spain that was not damaged by the codlin moth, 

 but as there was no export trade in apples, and the whole of the crop was 

 usually turned into cider, the growers took no notice of wormy apples —
