The March issue of the bulletin Of the
Ohio Experiment station contains an
article by DIR. HI. J. Detmers, veterin-
arian Of the station, on the above
named disease, of which the following
is summary: . tlN Is Htilu iH
Actinomycosis-"Big jaw" or ''lump
jaw'' of cattle, "big head' of hOrses--is
caused by parasitic fungus, which
grows within the bony or 6eshy tissues
and is generally found in the jaw, but
sometimes in the tongue, in the lungs,
and in other parts ofthe body. ~,
This fungus propagates by spores, "
corresponding to the seed of the higher
plants, which are widely disseminated,
and which 6nd an entrance to the
animal through wounds or a0raslons OF
the skin or internal membranes,
Through the temporary exposures of the
tissues in shedding teeth, etc.
When suitably lodged in the animal,
these spores produce nests of fungi
which may be distinguished by the un-
aided eve as minutely lowish specks,
but which appear under the microscope
to be around or oval in shape, and to be
distinctly radiated from center to cir
cumference.
The disease produced by this fungus
| Is purely local In its character, affecting
only the tissues in which it is immedi-
ately situated, and the final emaciatiOn
and decline of animals affected with II
are due solely to the inability Of the af-
| fected animal to masticate sufficient
food to keep up its condition.
The cure for actfnomycois Is either
to cut out, or to destroy with caustics
the ease-produeing fungus. II the
diseased growth has penetrated the
bones. or is SO located that neither oi
these methods can be employed with,
out interfering with important blood
vessels or other organs, no cure can be
effected; but if it be simple sarcOma.
tous (ieshy) tumor, and so situated thai
the surgeons knife may be safely used,
a cure may be effected by the complets
removal of the tumor, followed by an
ltiseptic treatment. In many case'
where it lis not practicable to us,
the diseased growth may be removes
| by the thorough use ofcaustics, minut'
directions for which are given in thu
Bulletin, but the operation is one which
can be performed with greater prospec
ofsuccess, by surgeon.
CULTIVATION OF coRN-ENsILAGl
CORR.
At the Ohio Experiment station
) plots of corn have been left without an,
cultivation whatever after planting
while other plots have received from
two to seven or even nine working
during the season. These experiment.
have been continued over seven sea
sons, and the general result is tina
while the unworked corn has in ever,
ease proved nearly or quite complet
failure, the plots receiving three o
four working, we'll distributed through
the season, have produced as larg
crops as those worked six or seven time
or more. ..
Comparisons of deep and shallow cul
lture have likewise failed to bring OIL
any market superiority of eithe
method.
The experiments of this station in th
culture Of corn for ensilage and in feed
ing the ensilage, point decidedly to tn
conclusion that best results will be oh
tanned by planting the corn early, q
such distance apart that the larges
amount of grain may be secured, an
cutting it when almost ripe enough fO
ldry-curing. The idea of sowing cor
. broadcast for fodder is thoroughly e2
ploded.
