lunar surface. I very much doubt whether any one has ever seen
anything on the moon which could not be made out in a clear,
steady atmosphere with a six-inch telescope of the first class.

Next to the moon, Saturn is among the most beautiful of celestial
objects. Its aspect, however, varies with its position in its
orbit. Twice in the course of a revolution, which occupies nearly
thirty years, the rings are seen edgewise, and for a few days are
invisible even in a powerful telescope. For an entire year their
form may be difficult to make out with a small telescope. These
unfavorable conditions occur in 1907 and 1921. Between these
dates, especially for some years after 1910, the position of the
planet in the sky will be the most favorable, being in northern
declination, near its perihelion, and having its rings widely
open. We all know that Saturn is plainly visible to the naked eye,
shining almost like a star of the first magnitude, so that there
is no difficulty in finding it if one knows when and where to
look. In 1906-1908 its oppositions occur in the month of
September. In subsequent years, it will occur a month later every
two and a half years. The ring can be seen with a common, good
spy-glass fastened to a post so as to be steady. A four or five-
inch telescope will show most of the satellites, the division in
the ring, and, when the ring is well opened, the curious dusky
ring discovered by Bond. This "crape ring," as it is commonly
called, is one of the most singular phenomena presented by that
planet.

It might be interesting to the amateur astronomer with a keen eye
and a telescope of four inches aperture or upward to frequently
scrutinize Saturn, with a view of detecting any extraordinary
