being that when the umbrella is
folded it is practically impossible to
distinguish any tknee, - and at the same
time stronger joint is formed. These
new frames are not only very light but
also very durable. The second improve
ment is i'll the ferrule, where a hard india
rubber tip has beer introduced, with the
effect of saving tke frame from Earring
and at the same time rendering the UNI
brella noiseless when used for a walking
stick.

London Industries says that the cement
by which many stone buildings in Paris
have been renovated is likely to prove
useful in repairing the foundations for
machinery. The powder which forms the
basis of cement is composed of two parts
OxiIlp of zinc two IF 1.lr1 he'd n ar,d
stone and one of pulverized grit, to-
gether with certain proportion of Ochre
as a cOloring agent. The liquid with
which this powder is to be mixed con-
sists OF saturated solution OF six parts
of zinc in commercial muriatic acid, to
which is added one part of Salammoniac;
this solution is diluted with two-thirds of
its volume of water. A mixture of one
pound of the powder TO two and Il half
pints of the liquid forms a cement which
hardens quickly and is of great strength.
new stirrup, which provides an abso-
lutte guarantee against being dragged,
has recently been patented by p. G..
Shadbolt. There is nothing peculiar in
the appearance of these stirrups at first
sight, but closer observation shows that
the strap ring is fitted into a spring clip,
which opens only laterally, and conse-
quently is kept securely closed so long as
the stirrup is perpendicular. But in the
event of the rider being thrown, the
strain on the stiTrup, should the riders
foot remain in it, would at once release it
from the strap, and so lessen the danger.
This simple appliance seems to offer a
ready means of safeguard in riding
horse that is at all likely to throw one.
A new candle has been brought out
which extinguishes itself in an hour.
This it does by means of 4 tiny extin-
guisher of tin which is fastened in the
wax by wires, and which efTeteually
performs its task. It is only neces-
sary TO remove this diminutiye extin-
guisher when its work is done, and the
candle is again ready to burn another
hour. An automatic gas extingGisher
has lately been patented by Joseph
Heronx of Yamachiche, Canada, which
consists of spring stop cork, which shuts
automatically when the gas is extin-
guished The mechanism used is based
on the llneal expansion of metals.
One of the troublesome questions which
architects have never been able to settle
is the placing of permanent foundations
under large buildings The latest ex-
