difference in the working- properties of the two soils owing to the 

 fact that No. 609 contains very little carbonates, while No. 616 

 contains nearly 6 per cent., the presence of which has a very profound 

 influence in making the clayey soils workable. No. 616 is also much 

 better stocked with jilant food materials. The presence of so much 

 carbonate of lime in No. 616 doubtless also is responsible for the fact 

 that lucerne has been found a suita])le crop for it. For lucerne to 

 thrive on No. 609 it would be necessary to apply lime to the soil or to 

 irrig-ate it with a water which contains plenty of lime. There is no 

 doubt, however, that No. 609 is a good wheat soil.
