 peat and bog in a different district, and advises as to the 

 methods of reclamation which he considers applicable. He 

 also examines samples and advises members as to their suit-

Experimental cultivation is Carried out on a large scale at 

 Flahult, where the work is seen and examined by numerous 

 visitors. The Society also encourages the formation of ex- 

 perimental fields on farms in different districts by supplying 

 seeds and manures gratuitously. Demonstration plots have 

 also been established with a view to educating the rural popu- 

 lation. Practical advice and assistance in dealing with peat 

 land can be obtained from an expert attached to the Society, 

 at a small charge per day for maintenance, and this is a 

 privilege which is much sought after. Illustrated lectures 

 are given, and short courses of instruction for agricultural 

 teachers are held. 



The Royal Swedish Agricultural Academy at Stockholm 

 also carries out manurial experiments on peat land, soil 

 analyses, and investigations at various other experimental 

 stations, supported by demonstration fields. 



This parasite attacks the leaves of the peach, almond,
