 DURING 1904. 



" // is of course recognised that no valuable practical work 

 can be carried on unless based on sound scientific principles. Hence 

 the necessity for maintaining the proper relationship between care- 

 ful scientific research and the practical application of such research"

INTRODUCTION- 



During the year, three hundred and twenty-five inquiries 

 have been received requesting information on Upwards of ninety- 

 three different animals : some of these not being of a particularly 

 injurious nature, no account of them is given in this report. 



Two hundred and twenty-six written replies have been sent 

 out, mostly pertaining to the identification of specimens and 

 remedial treatment recommended. 



For kindly examining and identifying specimens unknown 

 to me or for other information, I am much indebted to the 

 following workers : Messrs. A. D. Imms, B.Sc., A. H. Martineau, 

 F.E.S., Robert Newstead, A.L.S., Dr. D. Sharp, F.R.S., and Mr. 

 Fred. V. Theobald, M.A. 



During the year the following publication has been issued : 

 Reports on Economic Zoology. No. i. Some Recent Investiga- 

 tions on the Black-Currant Gall-Mite, Eriophyes ribis (Nalepa). 



When sending specimens correspondents are requested 

 not to place them loose in an envelope, but to enclose them in 

 tin or wooden boxes, together, in the case of insects or mites, 

 with a portion of the food plant, and not to punch holes in 

 the box, as larvae, small beetles, etc., often escape thereby.
