in his eye that gave
him this impression, for he has described a cluster in the constellation
Toucan in the southern hemisphere as containing a globular mass of
rose-colored stars inclosed in a spherical shell of white stars. Later
observers have confirmed his description of the shape and richness of
this cluster in Toucan, but have been unable to perceive the red hue of
the interior stars.

The eastern expanse of Sagittarius is a poor region compared with the
western end of the constellation, where the wide stream of the Milky Way
like a great river enriches its surroundings. The variables T and R are
of little interest to us, for they never become bright enough to be seen
without the aid of a telescope. In 54 we find, however, an interesting
double, which with larger telescopes than any of ours appears as a
triple. The two stars that we see are of magnitudes six and seven and a
half, distance 45", p. 42 deg., colors yellow and blue. The third star,
perhaps of thirteenth magnitude, is distant 36", p. 245 deg..

Retaining map No. 13 as our guide, we examine the western part of the
constellation Capricornus. Its leader alpha is a naked-eye double, the
two stars being a little more than 6' apart. Their magnitudes are three
and four, and both have a yellowish hue. The western star is alpha^1,
and is the fainter of the two. The other is designated as alpha^2. Both
are double. The components of alpha^1 are of magnitudes four and eight
and a half, distance 44", p. 220 deg.. With the Washington twenty-six-inch
telescope a third star of magnitude fourteen has been found at a
distance of 40", p. 182 deg.. In alpha^2 the magnitudes of the components
are three and ten and a half, distance 7.4", p. 150 deg.. The smaller star
has a companion of the twelfth or thirteenth magnitude, distance 1.2",
p. 240 deg.. This, of course, is hopelessly beyond our reach. Yet another
star of magnitude nine, distance 154", p. 156, we may see easily.

Dropping down to beta, we find it to be a most beautiful and easy
double, possessing finely contrasted colors, gold and blue. The larger
star is of magnitude three, and the smaller, the blue one, of magnitude
six, distance 205", p. 267 deg.. Between them there is a very faint star
which larger telescopes than ours divide into two, each of magnitude
eleven and a half; separated 3", p. 325 deg..

Still farther south and nearly in a line drawn from alpha through beta
we find a remarkable group of double
