TOP-DRESSING FOR GRASS.
\ correspondent of the Maine Farmer
writes Mr.. Joshua Howard, of this town.
reports a very successful experiment i'm
top-dressing moving lands lie spread
about three cords per acre Of horse and
OK manure composted with muck and
chip dirt, and worked over by hogs. At
ter spreading from the cart, a brush was
dragged over i to pulvcrizc it as much
as possible. This was applied i'm August
last year. and it was feared the severe,
drouth during the fall would render the
dressing imperative, but the increase in
the crop this year was remarkable, being
double that of last year on the same
ground. On one place, where foul grasses
had begun to appear, the top-drcssing
had the effect to bring up thick, stout
growth of timothy and red-top, 50 that
the poor grasses were not seen. Mr..
Howard is confident that the extra guam
tity of hay harvested this year from those
pieces of ground, pays him for all the
expense of top-drcssing.
DESTROYING COCKROACHEs.
For the destruction of the COckruach
Mr.. Harris, the late eminent cntomolD-
gist, recommends a mixture containing 20
tablespoonful of red lead. the same
amount of Indian meal with molasscS
enough to make a thick batter Set this
on plate at night in places frequentcd
by the insects and all that eat of il will
be poisoned. Another preparation is
composed of one teaspOonul Of arsenic,
with a tablespoonful Of mashed potato.
Crumble this every night at bedtime
where the insects will find il, and 10 is
said to be an efiectual poison. Great
care should be exercised in the use Of
such dangerous agents. An innocent
method of destroying cockroaches is to
place a bowl or basin containing a little
molasses on the floor at night. A bit of
wood, resting on one end on the floor
and the other on the edge Of the vessel,
serves as a bridge to conduct the insects
to the sweet deposit. Once in the trap
its slippery sidds prevent retreat, and
thus cOckrOaches may he caught by the
thousands. Various insect powders sold
at the druggists may be used for their
also.
BOILER INCRUsTATIONs Austrian
railway engineer has had the i'll "a of pro-
tecting the boilers of locomotives against
incruStation by means of copper plates.
The front and back plates of the bottom
Of the boiler Of an engine were covered
with sheet of copper l-2jth of an inch
i'm thickness, the middle plate Of the
boiler being left unprotected. The en-
CINE was worked for two years ona part
Of the line of the state railways where
the water was of very bad quality
When the tubes were taken out the in

and only from lis 10 10 of inch thick
on the copper plates. The iron was iu
many places corrodcd to the depth ct

.ircly unaffected, and the iron plate b.
Meath it, when uncovered, looked per-
ectly new. The particles demonstration
we're larger on the iron than on the cop
per. The cost of the copper covering is
,lid to he from $50 10 $50 per boiler in
Austria. Another engineer who exam
ned and reported on the arrangement,
says that the duration of the boilers is
doubled or tripled by the application of
the copper plates, which afford cNtraor-
binary security against explosion. Tie

IN iron and steel, which is porus and
slightly oxydzed and consequently the

copper the iron plates may he of less
thickness without risk; the weight Of the
boiler is thus considerably reduced, and,
astly, the expense forrcpairs is decidedly
Unfinished. A London journal cont
nents thus upon the above facts: This
of copper and iron in iron
ships has been found very injurious on
account of the galvanic action between
the two metals, and we would need more
satisfactory experiments with water or
different qualities, and particularly with
he acid water common i'm coal mines,
