8,306 lbs. of this manure applied per acre supply 
approximately the theoretical amount of nitrogen 
and of phosphoric acid and H times the theoreti- 
cal amount of potash required to replace what is 
temoved by two years' crops only ; while 20,248 lbs. 
applied per acre supply the theoretical amount of 
nitrogen, \\ times the theoretical amount of 
phosphoric acid and about lj times the theoretical 
amount of potash required to replace what is 
removed by two years' crops and primings. Cat- 
tle manure of this composition thus supplies the 
elements of plant food in relative proportions not 
so very different from those in which they are re- 
moved by crop, approximating much closer to the 
theoretical proportions than is the case with the 
two richer cattle manures referred to in the text. 
In the same manner to the tables ot Coffee Ma- 
nures on pages 156 and 157, Vol. XIII. may be added 
after Cattle Manure No. 2.

8,893 lb.-, of thi- cattle maimic applied per acre 
supply approximately the theoretical amount" of 
nitrogen and of phosphoric acid and "7 of the 
theoretical amount of potash required to replace 
these ingredients removed by two yearn' ciops. 
If, on the other hand, sufficient nlanare, viz., 
12,944 lbs. per acre l>e applied to furnish the 
theoretical amount of potash lequired, then 
there will be supplied 1-5 times the theoretical 
amount of nitrogen and 1-1 times the theoretical 
amount of pho phoric acid. Here again as in 
the case of tea this cattle manure supplies the 
ingredients of plant tood in proportions approxi- 
mating closer to those represented by Joss in 
crop than the two richer cattle manures referred 
to in the text or the various mixtures of bones 
and poonac usually employed.
