10 Liquid Manure. 



The mechanical analysis of this soil yielded the following 

 results : 



Moisture 2*42 



Organic matter 11*70 



Lime 1*54 



Clay 48-39 



Sand 35-95 



100-00 



On being submitted to chemical analysis, the following results 

 were obtained : 



Moisture .. 2*420 



Organic matter 11*700 



Oxides of iron and alumina 11*860 



Carbonate of lime 1*240 



Sulphate of lime *306

Potash (soluble in acid) ' .. .. *910 



Soluble silica , .. .. 4*090 



Insoluble siliceous matter 67*530

The composition of this soil differs materially from that used 

 in the preceding experiment. It is a soil which contains much less 

 lime and a good deal more sand than the soil from the College 

 farm. It belongs to the class of vegetable moulds, is moderately 

 stiff, and bears a good and tolerably abundant herbage. 



Soil and liquid manure were mixed as before in the proportion 

 of 2 of soil to 7 of liquid ; after 24 hours the clear liquid was 

 poured from the soil ; the liquid was then allowed to settle for 6 

 or 8 days and then filtered. Notwithstanding every care to 

 obtain a perfectly clear liquid, a little finely suspended clay passed 

 through the filter. This clay is mentioned in the subjoined 

 analysis as insoluble siliceous matter, and of course does not 

 belong properly to the liquid. 



The analysis of the liquid left in contact with the soil was 

 executed exactly in the same manner as that of the liquid in the 

 preceding experiment, and the following results were obtained :
