Liquid Manure. 
153 
Both the soil and subsoil, it will be seen, contain a large pre- 
ponderance of clay ; they are both very stiff, but when improved, 
1 am informed, are very productive. The chemical analyses of 
these soils furnished the following results : — 
Subsoil. Surface-soil. 
Moisture 9-46 3-91 
Organic matter and water of combination 4"87 4'80 
Oxides of iron and alumina 17'38 7"85

The surface soil exhibited bits of chalk, flint, and burnt clay ; it 
had evidently been dressed with burnt clay at some time or other. 
Equal parts of surface and subsoil were mixed with liquid 
manure from Tiptree Hall Farm ; soil and liquid were repeatedly 
agitated and then left to settle for three days, after that period 
the clear liquid was drawn off and analyzed as before. The 
filtered liquid manure had the following general composition per 
gallon : — 
*Water and volatile ammonia compounds 69,954"92

The residue which was left on evaporation to dryness, on 
analysis was found to contain in 100 parts :• —
