In comparison with the liquid manure used in tlie four pre- 
ceding!^ experiments, the Tiptree Hall liquid is very weak. It 
contains scarcely 30 grains of solid matter in tlie imperial gallon,

contains clay in large preponderance, an appreciable quantity of 
lime, and but little sand : it is, in fact, a very stiff soil. According
