These quantities would be for bearing trees of medium age; for 

 younger trees they may often be profitably reduced by a third or 

 more, and for older trees they should be increased. These dressings 

 are suggested as a first treatment for average conditions, to be varied 

 according to results. Annual applications of the artificials, with stable 

 manure at the rate of ten tons per acre every third or fourth year, are 

 thought likely to give the best results, but it must be remembered that 

 the effect of the first dressing may not be apparent till the second year 

 or even later. 



Everyone who cultivates fruit for a living should set aside a small 

 section of the orchard for experimental purposes, and endeavour to 

 find out by actual trial the methods of manuring, pruning, spraying, 

 and general management which are most suitable to his special condi- 

 tions. 



Occurrence of Codling Moth in Walnuts (" On the Nut-feeding 

 Habits of the Codling Moth/' U.S. Dept. of Agric, Bureau of Ento- 

 mology, Bull. No. So, Part v.).— The Codling Moth (Carpocapsa pomo- 

 nella) is usually a serious enemy to apples and pears, but it is reported 

 in this bulletin that a somewhat extensive infestation of walnuts has 

 occurred in California. So far all observations indicate that only the 

 later broods of larvae attack the walnuts, as no walnuts could be 

 found showing early injury, that is, before the shell hardened. Assum- 

 ing that the larval life in walnuts is the same in length as in apples 

 and pears, the earliest date of infestation would be late August or early 

 September. The Bartlett pear, which is grown in the district where 

 the infestation has occurred, is picked prior to this time, and before 

 all the second brood of moths have developed. It is probable that these 

 late-appearing individuals seek the walnut as the only remaining 

 plant suitable for egg-laying. 



OFFICIAL NOTICES AND CIRCULARS. 



The Board of Agriculture and Fisheries have recently issued the 

 following memorandum relating to the granting of licences for the 

 Licences for the removal of gooseberry bushes affected with 

 Removal of Gooseberry American Gooseberry Mildew :— 

 Bushes affected with In consequence of the spread of American 

 American Gooseberry Gooseberry Mildew over a large part of Great 

 Mildew. Britain during 19 10 the Board of Agriculture 



and Fisheries have found it necessary to schedule as diseased a very 

 large number of gardens, among which several important nurseries 

 are included, and to prohibit the movement of gooseberry and currant 

 bushes from them except under certain conditions. 



In order, however, to avoid as far as possible the injury to trade 

 which such restrictions may cause, the Board are prepared to sanction
