age of only II bushel of barley grain
and II cwt. of straw per acre per an
mum. more over the last seven years
than over the first 20 years, where the
application Of the dung was continued
Where the dung was discontinued after
90 years, the produce OF grain was, over
the next seven years, not quite three
fourths as much, and that of the straw
but little over two-thirds as much as
where II was continued. The average
annual deficiency was lSf bushels OF
grain and 81 cwts. Of straw. Compared
with the continuously unmanured pro-
duce over the same periods (Which,
however, declined considerably over
the later years, it is seen that the an
nually applied dung gave an average
increase, over the first 20 years oil 2sf
bushels Of grain and l69 cwts. OF straw
and over the last seven years OF 50
bushels of grain and % cwts. OF straw.
And where the dung was discontinued
over the last seven years, there was an
average increase of nearly % bushels OF
grain and l3} cwts. Of straw over the
continuously unmanured produce. In
the last year oFthe seven, 1878, the
plot where the application OF dung was
continued. gave S6i bushels of grain
and nearly 26s cwts. of straw more than
the unmanured plot and the plot
where the dung was discontinued gave,
in the same or seventh year ofthe dis
continuance, nearly II bushels OF gram
and nearly 10s cwts. Of straw, more
than the unmanured. 1t is obvious,
therefore, that the sidue ofthe ~
years. applicatiouof dung is still yield
ing increase. It is, however, gradually
declining. But there is no doubt that
the residue will continue to DO effective
In q still more declining ratio for many
ysars 10 come. 1t would, indeed, take
considerably more than century at
the present rate TO recover in increase
of produce all the nitrogen OF the
manure, which has not yet been so re-
covered.
Tuning now to the results obtained
with meadow hay: as already stated IA
tons of farmyard manure were applied
per acre annually for eight years in sue
cession, and the produce has since been
taken for Is years without MANURE
The table shows the average annual
produce and increase OF hay over the
eisht years Of the application, and over
the frst five, the second five, and the
third Hve years Afterwards. 1t will be
observed that over the 8 years OF the
application the average produce OF hay
was nearly tons cwts.; and the ay-
erage increase over the continuously
unmanursd produce was not quite ton
Over the Hrst years alter the cessation
Of The application, the average produce
Was about 2 cwts. less; but, SUBJ
stansialIy, both produce and increase
averaged much about the same as over
the years of the application Over
the second years, the produce dimin-
ished 10 less than three-fourths as much
as oyer the first S, and the increase was
little over 10 cwts. of hay per acre per
snnum. During the last of the Is
year,, the produce was little more than
bali as much rs its original amount,
andthe increase over the unmanured
produce of the same period was not
quite 2 cwts.
During the eight years OF tbs appli-
cation OF the dung there was obtained,
in I'll, IL tons 8 cwts Of hay, correspond
inc to 7 tons 10 cwts. Of increase over
the as years there were obtained
2s tons u cwts. corresponding to .
tons ~ cuts. OF increase, due to the
