le DIR. Wild, president of the Interna-
Il tional Polar Commission, has issued a
If circular stating that six countries have
y already intimated their intention to CO.
b operate in carrying out the scheme of
t simultaneous meteorological, magnet
< lcal and other physical observations, in
! the Arctic regions. These countries.
, with the proposed stations, are Den
J mark at Upperniyik, Norway in Fin
] mark, Austria Hungary in Jan Mayen, or
perhaps East Greenland, Russia in Nov
ayaZemyla and at the mouth of the Lena.
Sweden in Spitzbergen, and the United
States at Point Barrow and in Lady
Franklin Bay. Should other countries
send in their adhesion to the scheme.
| this disposition of the stations may be
! somewhat modified There is a prob
ability that Germany may establish
station in the Island of South Georoia
and France station at Cape Horn. An
interesting feature in the scheme is that
two OF the eight proposed Arctic sta
tlons are to be equipped at the expense
OF private individuals, viz: the station in
Jan Mayen or in East Greenland, at the
expense of Count II. Won Wilczek, of
Vienna, and the station in Spitzbergen,
by nj. Il. o. Smith, of Stockholm.
In the northern and foggy parts of
Japan 1t is the custom for mariners to
estimate their distance from the shore
by blowing their steam whistle, and OBJ
serving the time it takes for the echo to
return to them but on certain foggv
days, and with a particular configuration
OF the land, the echo does not come
back, so the method is misleading. It
has occurred to Professors Ayrton and
Perry, however, says. Engineering, that
ii the source of sound were placed un-
der water at depth of say thirty feet,
where profound calm reigns even in
stolmy weather. the method would be
free of these drawbacks. They pro
pose to lower into the sea a strong mu-
steal tongue or reed vibrated by an in
termittent electro magnet, and to listen
for the returning echo of the note emit
ted by the reed. This could be done by
dipping a wooden or metallic surface into
the water and applying the ear to it,
The sides of the ship itself might even
be found to catch the echo above
the noise Of the waves. The idea Of sub
marine sirens as coast warmers was
broached five years ago, but has never
been adopted. Professors Perry and
Ayrton's plan is somewhat different, but
that it is not wholly impracticable is
shown by the fact that Messrs. Colladon
and Sturm distinctly heard, through the
waters of Lake Geneva, the sound of
bell struck nine miles distant.
