desirable points, we often advise their en-

one inch should ever be used those which

IA good way to obviate the Objectionable
feature Of rust is to coat the interior with
hydraulic cement. The Me- use and NAL

duced the waters of Spot Pond into those

tion is wholly prevented by this device.
Large pipes are nov successfully construct
ed of cement, with a thin iron pipe upon
which it rests interiorly end exteriorly.
Pipes of this kind which have been sever
al years in use, we believe, continue to af-
ford the highest satisfaction. .n'. ...
''i' ''A GUTTA-pERCHA PIPE. .''
In seeking for satisfactory materia,
for water-pipes, the curious vegetable sub
stance, gutta-percha, has been used to
some extent. All metallic contamination
is at once entirely avoided by the employ
ment of this material, and apparently it
has much to recommend it to favor; but,
like a thousand other good things, it has
Objectionable features. Gutta-percha i'm
parts to water in contact ith it an un-
pleasant taste, and also, in some locali-
tiles. it undergoes kind Of spontaneous
decomposition, by which it is rendered
worthless. ' "' ''-
If, however, these objections did not
exist, we presume the item Of cost would
come in to drive it in great degree from
the market. At the present time we
think but little Of this pipe is used in any
section cf the country for water conduit.

| Compound metals used for water-pires
must be looked upon with disfavor by
chemists. And yet some alloys resist OK

most remarkable manner. We know Of
no subject which more imperatively de-

than that of alloys.
It is a curious fact that aluminium and
magnesium, when confined with each 9th
er and with other metals in certain pro
portions, will oxidize so rapidly as to. fal
into powder almost instantly; while ii
other proportions the compound resists the
action of oxygen to a degree approaching
that Of the noble metals.
A mixture Of copper and zinc may pos
sibly be devised, which, when formed int
pipe, will convey water safely; but O
such we have no knowledge. A brass
water-pipe is now being manufactured ant
introduced, we learn; but such should
not be hastily adopted by any one. ..,r1

The common glazed clay or ''stone
ware" pipe has been used to considerable
extent for conducting water, and where
the pressure is slight it may serve a good
purpose. There is a difficulty, however
in securing the sections free from minute
ori6ces which render them leaky, and al
so it is troublesome. to form tight joints
When made of,extra thickness and put ii
