Never was dawn so welcome to the weary observers, who were not nearly so
much chilled by the November weather, as by the disappointment at the
meager display. Possibly the bright moonlight in the earlier part of the
watch had dimmed the splendor of many of the Leonids, but where were the
tens of thousands which were said to have fallen in 1833, or even the
thousands which were observed in 1866, for not even one hundred rewarded
us for our vigil in 1899? However, we were told to watch again the
following year, when possibly we might meet with better luck, but our
record as given in _Popular Astronomy_, Vol. IX, 1901, shows that only
forty-four meteors were seen between midnight and dawn, and of these,
seven were intruders. The cause of the failure of the return of the
Leonids in 1899 was due to the fact that the planet Jupiter had so much
disturbed the orbit of the meteor group of 1866, that from calculations
made it was estimated that it would pass about two millions of miles
outside of the earth’s orbit, and thus escape collision with our
atmosphere. For this reason, few meteors were seen in 1899 and 1900,
though in 1901 and 1903 pretty brisk showers of Leonids were visible,
though they were nothing like the magnificent displays of 1799, 1833,
and 1866. A new shower derived from Pons-Winnecke’s periodical comet was
witnessed from Bristol on June 28, 1916. A very brilliant and abundant
return of this display may occur during the last week of June, 1927,
when the earth and comet will be exceedingly near each other.
The following suggestions may be helpful to those who may feel inclined
to make a hobby of recording meteors which are far more plentiful (quite
a number making their appearance on any clear night) than comets, which
are, comparatively speaking, rare visitors. Practically no appliances of
any kind are required. The main essential is a knowledge of the various
constellations and of the stars visible to the naked eye, a knowledge
soon acquired by a study of some good atlas of the heavens, such as my
father’s _Half Hours with the Stars_. This contains twelve charts, one
for each month of the year, with accompanying letter press.
