Observations. 



This soil is closely similar to the Quebec soil in mechanical struc- 

 ture. It differ in possessing a large proportion of carbonate of lime. 

 All the factors determined are normal for a soil of good fertility. The 

 * available' potash is being re-determined. The available phosphoric 

 acid is equal to that of the Quebec soil and indicates a sufficiency of 

 this ingredient for all practical needs. 



Clearly a soil in need of good management on general agricultural 

 lines rather than starving from lack of plant-food. Fertilisers are not 

 expected to prove remunerative under present conditions. 



C. Koningsberg. Hon. Dr. Pringle, C.M.G. 



To test the value of analysis as a guide to manuring, it was decided 

 to carry out an experiment on a soil which was analysed for Dr. 

 Pringle in 1901. The figures and an extract from the report are given.
