Ether is so rare that its density, compared with water, is represented
by a decimal fraction with twenty-seven ciphers before it.

When the worlds navigate this sea, do they plow through it as a ship
through the waves, forcing them aside, or as a sieve letting the water
through it? Doubtless the sieve is the better symbol. Certainly the
vibrations flow through solid glass and most solid diamond. To be
sure, they are a little hampered by the solid substance. The speed of
light is reduced from one hundred and eighty thousand miles a second in
space to one hundred and twenty thousand in glass. If ether can so
readily go through such solids, no wonder that a spirit body could
appear to the disciples, "the doors being shut."

Marvelous discoveries in the capacities of ether have been made lately.
In 1842 Joseph Henry found that electric waves in the top of his house
provoked action in a wire circuit in the cellar, through two floors and
ceilings, without wire connections. More than twenty years ago
Professor Loomis, of the United States coast survey, telegraphed twenty
miles between mountains by electric impulses sent from kites. Last
year Mr. Preece, the cable being broken, sent, without wires, one
hundred and fifty-six messages between the mainland and the island of
Mull, a distance of four and a half miles. Marconi, an Italian, has
sent recognizable signals through seven or eight thick walls of the
London post-office, and three fourths of a mile through a hill.
Jagadis Chunder Bose, of India, has fired a pistol by an electric
vibration seventy-five feet away and through more than four feet of
masonry. Since brick does not elastically vibrate to such
infinitesimal impulses as electric waves, ether must. It has already
been proven that one can telegraph to a flying train from the overhead
wires. Ether is a far better medium of transmission than iron. A wire
will now carry eight messages each way, at the same time, without
interference. What will not the more facile ether do?

Such are some of the first vague suggestions of a realm of power and
knowledge not yet explored. They are mere auroral hints of a new dawn.
The full day is yet to shine.

Like timid children, we have peered into the schoolhouse--afraid of the
unknown master. If we will but enter we shall find that the Master is
our Father, and that he has fitted up this house, out of his own
infinite wisdom, skill, and love, that we
