WATERPROOF COATING FOR WMIs.-The follow |

KEEPING LEATHER HARNESS PLIABLE-It is
we'll known that leather articles, kept IN sta
bles soon become brittle in consequence OF
Hnmoniaeal exhaatOns, which affect both har-
ness hanging up in such localities and the SHOES
u those who frequent them. The usual APP
vkcations of grease are not always sufficient TO
meet this difficulty; but it is said that by AIDING TO

CULTIVATION or THR PLUM TREE BY SEEDLINGS.
A German ponologist gives certain figures in re-
gard to the cultivation of plum trees by winch
he shows that seedlings obtained by planting
approved varieties much more hardy and resist
cold and the injurious agencies OF insects
much better than cuttings or grlftiugs. This IS sup
posed 10 depend upon the more cquable nature Oh
the roots and their more perfect penetration into the
coil t. such depth that they are less exposed to the
action Of frost and Other injurious agencies.
WASHING WOODEN CIoTHING.-Articles of wooden
clothing. washed in ordinary soap and water, not
only shrink, but acquire peculiar fatty odor due
T. the decomposition of the soap by the Tactic and
acetic acids present in the Precipitation and conse-
oueut precipitation Of the greater part Of the fat OF
the soap IN the fiber of the wool According to Prot
Artns both Of these effects can be prevented by
sleeping the articles for several hours IN q warm,
moderately concentrated solution of washing Soda
then after the addition OF some warm water, and a
few drops of ammonia washing them ont and rms
ing them in ukewarm water.
AID IN ADVANCING TIE GERNlINAIIoN OF SEEDS
As a means of promoting the termination of fruit

mends the following simple preparation as tested
by his own experiences Seeds of apples. pears, &c,
are placed in a tumbler glass jar with sufficient
snanttv Of rain water TO cover them. and kept IN

VESSELS FOR TRANSPORTATION OF NHK.-WOoden
vessels Of about q gallons capacity, are highly rec
commended by Mr.. Byern, practical dairyman for
transportation Of milk 20 considerable distances
He givos the following his practice: The vessels
a. soon IA emptied arc rinsed with warm water ana
aept back; and since they remain in this half
sleansed condition q hours. they often acquire a
decidedly acid cdor which is, however, completely
removed by first washing them out thoroughly with
warm. not boiling water, then Tinsing them with
about three pints of solution of washing soda for
every 20 vessels. 10y pouring it from one to another
They are then placed, mouth downward on a shelf
in the open air until the next morning and shortly
before using, they again Tinsed with cold water
SUIPHUREr OF CALCIUM 4 REMEDY FOR PHYI-
IoxERA-A According TO WssOcQ, sulphUret Of cal
eiurn dug in around the roots of vines will havea
very powerful effect in destroying any Pkyiioreya
sastat,tc that may happen 10 infest them. This
gives rise 10 sulphuric acid, in consequence of
the moisture of the soil and the gentle disengage
Inent Of carbonic acid. 1t serves equally well to
destroy caterpillars aud other injurious insects
which are frequently difficult TO remove from
vegetation.
The same substance is also recommended for the
destruction Of masns for the agencies by which
spidemcs are transmitted, and also as not being
open 10 the objections 10 the ordinary disinfctants
introduced into water-closets, such suphate or
shlorde of iron. which, while destroying the hydro
sulphuric acid allows the development Of more
dangerous emauatiOns.
ADuITFRsuON OF MILK. - According TO Mr.. if
Alfred WanklyH, the most common modes
adulteraton of milk consist in removing
she cream In greater less quantity aud in
adding water; and consequently the testing Of milk
resolves itself essentially into the detection of the
sknnmiug and watering, and the measuring Of the
extent 10 which these operations have been carried.
For tins purpose ne finds It most salts

NAL composition Of milk or at least the average
limits of variation in tins respect, and then to find
ont what deviation from this average is presented
by any given sample.
The result Of many inquiries on his part is 10
