The heavens were richly but very irregularly inwrought with stars. The
brighter stars clustered into well known groups upon a background
formed of an enlacement of streams and convoluted windings and
intertwined spirals of fainter stars, which became richer and more
intricate in the irregularly rifted zone of the Milky Way. We, who
formed part of the emblazonry, could only see the design distorted and
confused; here crowded, there scattered, at another place superposed.
The groupings due to our position were mixed up with those which were
real. Could we suppose that each luminous point had no relation to the
others near it than the accidental neighborship of grains of sand upon
the shore, or of particles of the wind-blown dust of the desert?
Surely every star from Sirius and Vega down to each grain of the light
dust of the Milky Way had its present place in the heavenly pattern
from the slow evolving of its past. We saw a system of systems, for
the broad features of clusters and streams and spiral windings marking
the general design were reproduced in every part. The whole was in
motion, each point shifting its position by miles every second, though
from the august magnitude of their distances from us and from each
other, it was only by the accumulated movements of years or of
generations that some small changes of relative position revealed
themselves.
THE WORK OF THE FUTURE.
The deciphering of this wonderfully intricate constitution of the
heavens would be undoubtedly one of the chief astronomical works of
the coming century. The primary task of the sun's motion in space,
together with the motions of the brighter stars, had been already put
well within our reach by the spectroscopic method of the measurement
of star motions in the line of sight. Astronomy, the oldest of the
sciences, had more than renewed her youth. At no time in the past had
she been so bright with unbounded aspirations and hopes. Never were
her temples so numerous, nor the crowd of her votaries so great.
The British Astronomical Association formed within the year numbered
already about 600 members. Happy was the lot of those who were still
on the eastern side of life's meridian! Already, alas! the original
founders of the newer methods were falling out--Kirchhoff, Angstrom,
D'Arrest, Secchi, Draper, Becquerel; but their places were more than
filled; the pace of the race was gaining, but the goal was not and
never would be in sight. Since the time of Newton our knowledge of the
phenomena of nature had wonderfully increased, but man asked perhaps
more earnestly now than in his days, what was the ultimate reality
behind the reality of the perceptions? Were they only the pebbles of
the beach with which we had been playing? Did not the ocean of
ultimate reality and truth lie beyond?
