entirely To the partial absorption OF some; perhaps

since these absorbed ingredients are gwen up IN

ErYcrPo-sruSNUs METHOD OF P1AuNG.--A re-
Gently invented mode of plating, known as the
eerroStdunuS process. consists in the of cheap
white metal of which tin is the principal ingredient,
and which eau be readily deposited galv anically
upon AL metals excepting zinc. The articles 10 I've
plated are first thrown into bath of weak sulphuric
acld and water and then into q second strong bath
of boiling potash I've, where complete chemical
cleanness is effected. They are then suspended IN
a vat containing solution of metal, and having re-
manned there a sufficient length of time they are
"scratchedr by a rapidly revolving wire brush when
they are ready "a return to the customer.
In emerging from the VAT the articles are OF q anu
leaden color hut they are susceptible OF high pol
iSh very little short of thai of polished silver One
OF tho chief advantages of the method IS that II
ObyateS the liability of iron and steel goods TO rust,
and is proposed that where articles are TO he silver
plated a white undeT-cOat shall be first given by
means of this new material that when the silver
wearE Od 1t will show the silyer-whJe appearance
beneath.
The process is now being applied 10 coating vari-

SEEDING PLUM TREES-Au inspection of the
plum orchards and nurseries Of Hagensdorf in Sep
TENDER, 1871. demonstrated that seeding trees had
withstOOd the severity of the Winter much better
than those prupagated from suckers. Of the latter
thousands of old trees were killed as well beds of
young ones while adjoining beds of seedlings were
entirely unaffected Ii was also noticed that trees
xhiCh ahOuudpd in SprOufS generally al
fected than those from which tho sprouts had been
removed az an early period. IL IS also cOntended
that seedlings send out their roots more vertically,
and deeper down, and IN consequence are more
likely reach moisture in dry weather, and less liable
to injury by the plow ID cultivation or TO send up
suckers.
