PREFACE. 



The reception accorded to my " First Report on Economic 

 Biology " induces me to issue a second one treating of some of the 

 more interesting animals, plants, etc., that have passed through my 

 hands during 1911. 



To the many farmers, fruit growers, horticulturists, and others 

 who have assisted me, and whose kind appreciation of my work I 

 greatly value, I tender my sincere thanks. 



I am indebted to the courtesy of the Controller of His Majesty's 

 Stationery Office, and the Secretary of the Board of Agriculture and 

 Fisheries, for permission to use Figures 4 and 15, both of which are 

 from illustrations which have appeared in the Board's leaflets.
