pApEnrSG and painting are best done
IN c.ld weather, especially the latter,
for the wood absorbs the oil of paint
mich more than in warn weather +;
while in cold weather the oil hardens
on the outside, making a coat which
will protect the wood, instead OF soak

TO CLEAN MARBLE.-Marble OF any
kind, alsbaster, any hard stone or glass
NAV be repolished by rubbing it with a
linen cloth dressed with oxide OF tin

For the purpose a couple Of mere folds
of linen should be fastened tight over a
piece of wood, fiat or otherwise, accord

perfectly cleansed. This is best done
by making a paste Of lime, soda and
water, w%etting well the marble, and APP
plying paste. Then let it remain for a
day or so, keeping it moist during the
interval. When this paste has been re-
moved the polishing may begin, Chips

with emory and water. At every stage
of polishing the linen and pntty'pow-

polished by the same way.

VARIOUS theories have been adduced
to explain the motion of glaciers. Some
maintain that glaciers move under the
influence Of gravity, like n solid body
on an inclined plane, Others that the
movement is like that of yiscous sub
stances (such as tar or molasses.
Others still that it is due to pressure OF
the ice on itself, which alternately melts
and regeals, portions of the glacier fore
ing it forward. A French physicist, M.
Grad, has lately propounded n new
theory. He thinks the movement If

water through the assures, by the iu'
sion of the surface, then increases tho
original effect of the pressure by lncreas
ing the proportion of water assimilated
by the glacier under the influence Of
regulation. On the one hand, the sim
pie action of pressure explains the
movements of glaciers during the WIN
ter. On the other, the Influence OF IN,

the glacier, acceierates the movements
in spring and summer. In any case,
the movement arises from congelation

is furnished both by this pressure and
by intiltration of the product of surface
fusion. Other things being equal, n
glacier assimilates in its interior by
congelation a quantity of water which
is greater in proportion to Indebtedness
of the glacier and the number OF capll-
larry iisures. Hence, the movement ls
more rapid at the middle than at the
sides.
