Leaflet on the Large Brown Pine Weevil. 



An important leaflet (No. 8) has been recently issued by the 

 Board of Agriculture, dealing with the large brown pine weevil 

 {Hylobius abietis, L.). In this leaflet an excellent description of 

 the weevil and of its life-history is given, while the plants 

 attacked, the damage done, together with preventive and 

 remedial measures are dealt with in a thoroughly practical 

 manner. The beautifully reproduced photographs of the insect 

 at work are of outstanding merit. 



Every forester should procure a copy of the leaflet, which may 

 be obtained free of charge and post free on application to the 

 Secretary, Board of Agriculture for Scotland, 29 St Andrew 

 Square, Edinburgh. Letters of application so addressed need 

 not be stamped. 



Tree-Growth in 19 13. 

 The year 19 13 has been remarkable for plant-growth, and 

 trees are no exception to the rule. In the south of England 

 we had an unusually showery spring and early summer, followed 

 by some weeks of extreme heat, then showers all through the 

 autumn and early winter. This combination of circumstances 

 tended to produce growths above the average.
