bacteriology of the soil, its physical condition, position and 

 climate, and there was at present only one method which could 

 be used to throw light on the subject, viz., manurial experi- 

 ments, and he urged the carrying out throughout Germany 

 of comprehensive co-operative experiments. It is of interest 

 to note, in this connection, that this method has been strongly 

 advocated by the Board (see " Manurial and other Agricultural 

 Experiments," issued March, 1903). In close connection with 

 these lectures was that of Dr. Hiltner, who dealt with soil 

 bacteriology, describing the progress of the past three years 

 with regard to soil inoculation. 



Other lectures dealt with the use of lime, its effect on the 

 soil, its cost and profitable employment ; new varieties of 

 grain and other crops ; judging of varieties of seeds by inspec- 

 tion of the growing crop ; the progress of investigations into 

 plant diseases ; the protection of useful birds ; cultivation 

 of flax ; fruit cultivation ; and fish-farming. 



The Board have received a copy of Regulations, dated 



November 10th, 1904, for preventing the introduction of insect 



pests and plant diseases into the Transvaal.
