ops may be found many telescopes gorgeous in
polished tubes and brass mountings which, for effective work, are
absolutely worthless. On this subject, I consulted the most eminent of
all discoverers of double stars, an observer who, even as an amateur,
made a glorious reputation by the work done with a six inch telescope.
I refer to Mr. S.W. Burnham, of the Lick Observatory, who, in reply,
kindly wrote: "You will certainly have no difficulty in making out a
strong case in favor of the use of small telescopes in many
departments of important astronomical work. Most of the early
telescopic work was done with instruments which would now be
considered as inferior to modern instruments, in quality as well as in
size. You are doubtless familiar with much of the amateur work, in
this country and elsewhere, done with comparatively small apertures.
_The most important condition is to have the refractor_, whatever its
size may be, _of the highest optical perfection_, and then the rest
will depend on the zeal and industry of the observer." The italics are
mine.
Incidentally, it may be mentioned that much most interesting work may
be done even with an opera glass, as a few minutes' systematic
observation on any fine night will prove. Newcomb and Holden assure us
that "if Hipparchus had had even such an optical instrument, mankind
need not have waited two thousand years to know the nature of the
Milky Way, nor would it have required a Galilei to discover the phases
of Venus or the spots on the sun." To amplify the thought, if that
mighty geometer and observer and some of his contemporaries had
possessed but the "common telescope," is it not probable that in the
science of astronomy the world would have been to-day two thousand
years in advance of its present position?

ARCHAEOLOGICAL DISCOVERIES AT CADIZ.
Those who have had the good fortune to visit Andalusia, that
privileged land of the sun, of light, songs, dances, beautiful girls,
and bull fighters, preserve, among many other poetical and pleasing
recollections, that of election to antique and smiling Cadiz--the
"pearl of the ocean and the silver cup," as the Andalusians say in
their harmonious and imaginative language. There is, in fact, nothing
exaggerated in these epithets, for they translate a true impression.
Especially if we arrive by sea, there is nothing so thrilling as the
dazzling silhouette which, from afar, is re
