8 Composition of the Yellow Lupine, 



It is by rejecting- unusual or abnormal results, and striking an 

 average of numerous determinations of the same produce, that 

 practically useful data are obtained. Proceeding in this way, 

 the averages of different analyses often agree very closely. Thus 

 the percentage fcf water in the various clovers on an average 

 amounts to : 



According to Way 78'25 



Voelcker 78'65 



In the absence of any other analysis of lupines cut down in a 

 green state, besides that given above, the expressed opinion can 

 only apply to the particular crop analysed, and our judgment 

 respecting the average nutritive qualities of lupines in comparison 

 with other food must remain suspended until the data are pro- 

 duced on the strength of which a trustworthy opinion can be 

 formed. 



On the Soil suitable to the Cultivation of Lupines. 



It has been already remarked that lupines succeed well on 

 light, sandy, and even poor, blowing sandy soils. The agricul- 

 tural capabilities of the soil on which the yellow lupines were 

 grown in the experiment under discussion are described in 

 detail in Mr. Kimber's letter. I can therefore proceed at once 

 to state its chemical composition. 



The analysis was made from two samples, taken at the depth 

 of 6 and 12 inches respectively, and then well mixed. 



The first sample contained a percentage of 



Water 1-12 



Organic matter 2-07 



The second, which was darker coloured, 



Water* -81 



Organic matter '81 



The mixture gave the following results when submitted to a 

 minute analysis :
