extent about London; about five 
or six loads to the acre, which con- 
tain on an average 250 bushels. 
They are most beneficial on strong 
soils, and their duration exceeds 
that of any other manure. ‘The 
effects have been visible for more 
than thirty years. The dust and 
refuse of bone manufactories is also 
avaluable manure, particularly for 
- drilling. 
SHeep’s TRoTTERS are a powerful 
manure, and usually sold by the 
quarter, with felt-mongers’ cuttings ; 
they are commonly applied in the 
Proportion of four or five quarters 
' to theacre, but eight are sometimes 
used. They should be plonghed in 
not less than six or eight inches 
_ deep, to prevent the attraction of 
_ Yermin and dogs. 
_ twenty bushels is the 
Harr of hogs is sometimes sold 
in great cities, and from sixteen to 
quantity 
usually applied to an acre. 
Fearuers are found to be a 
powerful manure, and twenty-five 
bushels an acre have been spread 
with much success ; ten bushels to 
an acre yiclded a produce of forty- 
eight bushels of white wheat, while 
- the same quantity unmanured pro- 
duced only twenty-eight bushels. 
Fisu of all kinds is one of the 
most effective manures that can be 
carried into our fields. The whale. 
blubber offal never fails of pro- 
ducing great crops wherever it is 
applied; pilchards and _ herrings 
produce the same effect. In Dorset- 
shire Mr. Davis spread them fresh 
at one shilling per Joad, and 
ploughed them in for wheat with 
much benefit, but they are usually 
applied mixed with salt. Ju the 
feus the small fish called stickle- 
backs are obtained out of the 
rivers, and applied to this purpose. 
971 
Graves, or tallow-chandlers’ re- 
fuse, is purchased for manure, and 
from ten to fifteen hundred weight 
are-commonly spread upon an acre. 
The effects from them on poor 
sandy soils, are very great in turnip 
crops. 
Wootten RAGs, chopped in small 
pieces, are frequently applied as 
manure, from ten to fifteen hundred 
weight to the acre. It has been 
noticed in Hertfordshire, that they 
are most beneficial on dry and 
sandy soils. They become the 
food of plants in common with all 
other animal substances, and also 
attract aud retain much moisture 
from the atmosphere. 
Curniers’ sHAvines, and fur. 
riers’ clippings, are bought in Lon- 
dou and other populous places. 
When cornseils high they are eagerly 
sought for; for, though they are 
an expensive, yet they are a bene- 
ficial manure, but do best on dry 
soils. 
LioRN SHAVINGS are also bought, 
and applied at about thirty bushels 
to the acre; they are applicable to 
all soils, but succeed best on all in 
wet seasons. 
‘lhese. manures are all animal 
substances, and their nature and 
properties are in all resolvable into 
the same parts as yard and stable 
dung; they contain the principles 
which by every consistent theory of 
vegetation are necessary to the food 
of plants, and the practice of the 
farmer is in perfect unison with the 
theory of the chemist; for every 
husbandman knows, or ought to 
know, that every animal matter 
whatever, will fertilize his fields. 
‘The only question of preparation 
which can arise, is whether these 
substances should be immediately 
applied ta the soil, er prepared by 
fermen.
