of poultry, which are being carried on in Europe and other 

 countries, together with a report of the actual proceedings of the 

 Congress, which was attended by the largest gathering of persons 

 interested in poultry keeping that has ever been known. 



The reports are in the form of papers which were read at the 

 Congress by the delegates from governments, research stations, 

 universities and colleges, members of the more important 

 societies, and well known commercial poultry breeders. 



This unique collection of varied and up-to-date useful informa- 

 tion on all matters referring to poultry should prove of 

 inestimable value to all engaged in the development of the poultry 

 industry in this country. Universities, colleges, farm institutes 

 and other educational centres should endeavour to obtain these 

 volumes for use in their libraries. Private and commercial 

 poultry keepers should also obtain them as they contain the 

 latest information on the various phases of the poultry industry. 



Copies may be obtained from C. S. Th. Van Gink, Office of 

 Secretary General, 30, Bezuidenhoutschewez, The Hague, 

 Holland. The price of the two volumes is £1, plus 2s. 6d. postage. 

 International post money orders must be used. 



A supply of Volume I has been received by Mr. T. B. Bobinson, 

 3. Vincent Square, Westminster, London, S.W.I, who will 

 supply copies on receipt of 10s. 6d. plus Is. for postage. 

 Volume II will be available shortly.

 at Shinfield, where the trials have been 

 carried out, is 200 ft. above sea level, and there is a general' 

 opinion that the rainfall is higher in the Thames Valley below. 

 The economic value of spraying probably therefore holds over 

 quite a considerable area, even in this comparatively dry part 

 of the country. 



During the course of the experiment four plots, of J acre 

 each, were measured every year and treated as follows : — 



(a) Not sprayed; (b) Sprayed once, early: (c) Sprayed once, 

 late; (d) Sprayed tw T ice, early and late. 



The early spraying was given about the beginning of July, 

 about a fortnight after potatoes were earthed up, and the late
