218 LETTERS TO DR. FLETCHER [CHAP. xx. 



kind co-operation have been an immense help to my work 

 and me for many a year, which I have never ceased to 

 appreciate most gratefully. I am working now on my next 

 Annual Report. There has been a good deal of nice fresh 

 matter sent in, and (so far as I could) I have tried not to go 

 over old ground. I have a grand paper on Locusts (fig. 55), 

 my specimens being identified at Madrid by Senor Don Igo 

 Bolivar. Wasps were a terrible plague and I have got 

 some charming observations, so entertaining ! but I have 

 taken great care to have them on good authority and 

 M. Schoyen kindly sent me some notes by the Swedish 

 State Entomologist of an enormous appearance at Tromsoe 

 a few years ago. As this is so high up in the Arctic circle I 

 thought the record would be of interest scientifically, and it 

 is so spirited I have had many a good laugh over it (p. 239). 



But what I hope you may be really pleased with is, that 

 through the kind introduction of Dr. Friedrich Thomas, of 

 Ohrdruf, whom you will know, I think, as one of our lead- 

 ing European Phytopathologists, I was put in communica- 

 tion with Dr. A. Nalepa (of Vienna), who for some years 

 back has quite especially devoted himself to the study of 

 Phytoptidce (Blister galls). So that now we have in his 

 successive publications first-rate specific descriptions, with 

 measurements and everything requisite for certain identifica- 

 tion of all the species which he has studied so far. Also in 

 very many cases he gives good magnified figures, and he 

 added* to his many kindnesses to myself by sending me a 

 plate with the details of the creatures marked with the tech- 

 nical names. In his treatises already published he has 

 given excellent accounts of very many species as well as a 

 good serviceable classification, and I rather think that the 

 work which has been coming out in the Reports of the 

 Imperial Scientific Society of Vienna is to be completed 

 this spring. 



This letter has been lying by me for a few days for an 

 addition I wanted to make, and now I have to thank you 

 very heartily for the great kindness which you have shown 



to poor Mr. T [a West of England farmer who had 



been unfortunate]. If he can manage to adapt himself to 

 circumstances your timely and great assistance will have 

 been the means of setting him up again. I doubted rather 

 whether it was right of me to trouble you about him, still I 

 thought I would venture, and indeed your help will have 

 been the means of saving him from going quite down. I 

 had no idea (no more apparently than Mr. T ) that his
