Kramer, of Chemnitz, Is novelty in
flooring material. being a special pre-
paration of paper pulp which is sold as
a dry powder. When mixed with wa
ter, it may be spread like mortar over
stone, cement or wood, where il dries
quickly, aud may be smoothly planed.
Ii may be tinted almost any color,
adapting 1t for parquetry with varie-
gated BORDERS, or for panels and mosa-
ics. Among the advantages claimed
are freedom from crevIces, deadeniug
of noise aud poor conduction of heat,
considerable elasticity, safety from fire,
aud remarkable durability. II may be
used for wainscoting aud other archi-
tectural purposes, as well as for floor
ing. A siIll more curious use for paper
is announced ia the form of a bathing
towel, which consists of full suit of
blotting paper into which the bather
steps from the water. 1t dries the en-
tire body in second.
Specimen sections of a terrestrial
globe 81 feet in diameter, the scale he

Mr.. T. Ruddiman Johnston, F. r. G. /
s, who believes such a globe can he
finished in two years. Every impor- /
tant geographical feature aud every /

will be viewed from a spiral gallery /
running several times around it TO the 4
North Pole al the top.

When telephone is placed sufficiently i
near telegraph line, yet without ac- I
tual contact, certain sounds are heard 4
on the passage OF current along the 4
telegraph liEe, anu uy long experiment /
this observer has been able To separate I
these sounds into the character of the +
Morse alphabet, and u draw up sys-
tenn by which any person eau learn
with practice to read the message pass
ing over the wires from the telephone
sounds. This makes il practicable to
tap" a telegraph line without inter I
fering with its current or giving any
indication whatever TO stations along /
the line.
