that Of the second (also in the green state) TO
milking COWS, and tina, of the thisd vas to be
made into hay.
BY the application OF sewage to grass land
during the Winter months, very early cut Of
grass was obtained, although this increased
product is small for the sewage employed. The
period during which an abundance OF green
food was available was also extended consid-
erSbly, at the end of the season as well as the
beginning, and the more so in proportion to
the sewage employed, up to the highest amount
used-9, 600 tuns per acre. One OF the expert
mental felds--the less fertile one-gaye a
smaller product than the other vixen both
were unsewaged; but under q liberal dressing
with sewage, the less fertile one cqualed the
other. Taking the average for three years, and
in the two fields, the amount OF produce OBJ
tanned without sewage was about - tuns OF
green grass per acre per amum, or about s
tIms Of hay; and with 5000, 5000, and 5000
tuns OF sewage per acre per annum, the amounts
were, respectively, about 22i, 30,, and $2i tuns
OF green grass, equal respectively (reckoned
according to the per contsge Of dry substance in
each) TO about 8, 81. and 81 tuns OF hay.
The largest quantities. Of produce per acre
were obtained in the third year of the expert
ments. and with 1900 tuns Of sewage per acre,
per annum; namely, in one field 50 tuns, and
in the other g tuns Of green grass, equal re-
spectively to about 81 aud tuns Of hay. The
average increase obtained for each 1000 tuns of
sewage was tuns Of green grass when 5000
tuns per acre per annum were applied; when
5000 tuns per acre were applied, 4 tuns and
when 9, 900 tuns were applied, 3 tuna 3. cwt.
The amount Of produce obtained per acre in
creases directly as the increase Of sewage, up TO
1000 luns per acre; but when the amount APP
piled exceeded that, theincrease of produce was
in much smaller ratio than when smaller
amounts wore used. Experiments with rye
grass were made, in one season only, AID with
iag less thoroughues,, but the general result in
dicated little variation from those obtained with
meadow grass.
When cut and given g-een to iaterng oxen
Z led up under cover, more scwaged tim un5ew-
aged grass was both consumed By agiyen weight
of animal within q given time, aud was required
TO produce given weight Of increase; but
when dry or solid substance was employed,
these result, were exactly reversed. when all
grass alone was given, the result waeveV TN
sai slactory; but with oi.cake added, the result.
in point Of inc.eaed weight, was not far short
OF the average result when oxen are fed under
cover on good mixed diet. The money return,
whether reckoneda per acre or for a given
amount Of sewage, was much less with tatten-
ing oxen than with milking COWS.
When COWS received all they wanted Of
scwaged OF unscwaged grass, q given weight OF
animal Wa more productive, both OF milk and
increase Out especially o! milky. on the sew
aged than the unsewaged grass. From given
weight OF green. unscwaged gris, a greater
amount Of milk was produced than from an
eQu,l amount Of sewaqed gIas bat when both
were used dr.. tie result, wcge reversed. By
the AID Of sewage, the time that M acre would
keep q cox, and tho amount Of milk obtained
from the produce Of an acre, were increased be
tween three and iour-iold; and il was estimated
that, with an application Of about 5000 tuns
o. savage per acre per annum TO meadow
land, an average gross produc, of not less than
1000 gallons Of milk per acre per annum may
be expected. In experiments with Italian rye
grass--madef for one season oIl va given amount
OF sewage resulted in greater return Of milk
than with meadow grass With al application
Of about 5000 tuns Of sewage per acre per an
nun, all average gross return Of from $50 to
$50 per acre may be obtained, taking milk at
eight pence per gallon.
Tile tables Of which the above statements
are partial summary are too minute and vpiumi-
nous to be quoted in anything Ike an entire
condition. AT another tine, however, We hope
10 present the essence 81 some OF them at least.
