's Table, given in the appendix, it will be
seen that clover-hay contains only 1.97 per cent of nitrogen and 5.7 per
cent of ash. Mr. Lawes' clover contains more nitrogen and ash. This
means richer land and a less mature condition of the crop.

The cereal grains, wheat, barley, oats, and Indian corn, stand next on
the list, being worth from $6.32 to $7.70 per ton for manure.

"Meadow-hay," which in the table is estimated as worth $6.43 per ton for
manure, is the hay from permanent meadows. It is a quite different
article from the "English Meadow-hay" of New England. It is, in fact,
the perfection of hay. The meadows are frequently top-dressed with
composted manure or artificial fertilizers, and the hay is composed of a
number of the best grasses, cut early and carefully cured. It will be
noticed, however, that even this choice meadow-hay is not as valuable
for manure as clover-hay.

English bean-straw is estimated as worth $3.87 per ton for manure. The
English "horse bean," which is the kind here alluded to, has a very
stiff, coarse long straw, and looks as though it was much inferior as
fodder, to the straw of our ordinary white beans. See Wolff's table in
the appendix.

Pea-straw is estimated at $3.74 per ton. When the peas are not allowed
to grow until dead ripe, and when the straw is carefully cured, it makes
capital food for sheep. Taking the grain and straw together, it will be
seen that peas are an unusually valuable crop to grow for the purpose of
making rich manure.

The straw of oats, wheat, and barley, is worth from $2.25 to $2.90 per
ton. Barley straw being the poorest for manure, and oat straw the
richest.

Potatoes are worth $1.50 per ton, or nearly 5 cents a bushel for manure.

The manurial value of roots varies from 80 cents a ton for carrots, to
$1.07 for mangel-wurzel, and $1.14 for parsnips.

I am very anxious that there should be no misapprehension as to the
meaning of these figures. I am sure they are well worth the careful
study of every intelligent farmer. Mr. Lawes has been engaged in making
experiments for over thirty years. There is no man more competent to
speak with authority on such a subject. The figures showing the money
value of the manure made from the different foods, are based on the
amount of nitrogen, phosphoric acid, and potash, which they contain. Mr.
Lawes has been buying and using artificial manures for many years, and
is quite competent to form a correct conclusion as t
