preface* ENTOMOLOGY 



LIBRARY 



IN issuing a. Fourth Report on the Injurious Insects and other 

 Animals of the Midland Counties of England, received from various 

 correspondents during the year 1906, it is again my pleasant duty to 

 acknowledge a Grant of 10 from the County Council of Warwick aiding 

 the publication of this Report, my thanks are also tendered to the Council 

 of the Birmingham Natural History and Philosophical Society, for their 

 continued assistance with my experimental work in Economic Zoology. 



I have pleasure in acknowledging the kind and valuable assistance 

 given me as regards the figures illustrating this work. To Prof. W. R. 

 Fisher I am indebted for the loan of the Figures II VI and 3, to Mr. G. 

 F. Strawson for Figure I and 2, and the Controller of His Majesty's 

 Stationery Office and the Secretary of the Board of Agriculture for 

 Figures i, 4, 6, 8 and 9, taken from the Board's Leaflets. 



The question of the continuation of the publication of an Annual 

 Report, of which this is the fourth, is one that will require very carefully 

 considering. The cost of printing, illustrating, and distributing two 

 thousand copies entails an expenditure of close upon 100, and unless 

 further financial assistance is forthcoming the Report will, I fear, have 

 to cease. 



Each year a wider circle of agricultural and horticultural friends 

 has been ever ready to afford me all the assistance in their power, and I 

 value the opportunity of once again being able to thank them for their 

 kind and valuable assistance.
