s of the same species of butterfly
or moth, mate them, and, as soon as any female deposited her eggs, place
the tiny pearl-like eggs in cold storage to retard their hatching, which
normally occurs, in the majority of species, within ten days or two
weeks.
This now was the usual mode of procedure followed by the field collectors
employed by Dr. Quint and Professor Boomly. And not only were the eggs
of various butterflies and moths so packed for transportation, but a
sufficient store of their various native food-plants was also preserved,
where such food-plants could not be procured in the United States. So
when the eggs arrived at Bronx Park, and were hatched there in due time,
the young caterpillars had plenty of nourishment ready for them in cold
storage.
Might I not, legitimately, have expected the Carnegie Educational
Medal for all this? I have never received it. I say this without
indignation--even without sorrow. I merely make the statement.
Yet, my system was really a very beautiful system; a tiny batch of eggs
would arrive from Ceylon, or Sumatra, or Africa; when taken from cold
storage and placed in the herbarium they would presently hatch; the
caterpillars were fed with their accustomed food-plant--a few leaves
being taken from cold storage every day for them--they would pass through
their three or four moulting periods, cease feeding in due time,
transform into the chrysalis stage, and finally appear in all the
splendour and magnificence of butterfly or moth.
The great glass flying-cage was now alive with superb moths and
butterflies, flitting, darting, fluttering among the flowering bushes
or feeding along the sandy banks of the brook which flowed through
the flying-cage, bordered by thickets of scented flowers. And it was
like looking at a meteoric shower of winged jewels, where the huge
metallic-blue _Morphos_ from South America flapped and sailed, and the
orange and gold and green _Ornithoptera_ from Borneo pursued their
majestic, bird-like flight--where big, glittering _Papilios_ flashed
through the bushes or alighted nervously to feed for a few moments
on jasmine and phlox, and where the slowly flopping _Heliconians_ winged
their way amid the denser tangles of tropical vegetation.
Nothing like this flying-cage had ever before been seen in New York;
thousands and thousands of men, women, and children thronged the lawn
about the flying-cage all day long.
By night, also, the effect was wonderfu
