On Liquid Manure. 



23 



In the first place, I would observe that five of the liquid 

 manures possessed the following specific gravities at 62 Fahr. : 



Liquid manure from Westonbirt 1-006 



Badminton T007 



College Farm, 1858 .. .. 1-0014 

 Tiptree Hall, clear liquid .. 1-0006 



Tiptree Hall, with sediment 1-001 



The specific gravity of these five liquids corresponds with 

 the amount of solid matters which each kind contains in solution. 

 To a certain extent the specific gravity of different kinds of 

 liquid manure may serve as an indication of their relative 

 fertilising value.

The difference in the amount of solid matters contained in 

 liquid manure are much greater than I expected to find them, 

 and, curiously enough, the liquid manure from Tiptree Hall, 

 which I anticipated would be very concentrated, was by far the 

 weakest of all ; the clear liquid contained in reality not more than 

 one-twentieth part of the amount of solid fertilising substances 

 which I found in the Badminton manure, and between one-fourth 

 and one-fifth of the amount contained in the Cirencester tank- 

 liquid, which I always considered very poor stuff, though it smelt 

 extremely disagreeable. 



In the next place I shall group together
