"Venus," when will be 30 N. of Spica and (October 22) less than 1° S. of 9. At the close of the year he will be in m close to and above (N.) of the red star Antares.

Jupiter will be brightest March 31, as an evening star. He will be an evening star from January 4 to October 19, and a morning star until January 4 and after October 19. At the beginning of the year he will be in m and remain in that constellation until November, when he enters - October 1 he will pass 3° N. of Spica, setting in the evening twilight. The superior planets, those exterior to the earth, may be very properly called 'all night" stars at or close to the time of their opposition, or when they rise at sunset and set at sunrise. This will be approximately the case with 4 until March 31.

Saturn will be brightest October 27, being at that time an all night star. He may also be considered an evening star until April 16 and after July 30, and as a morning star from April 16 to July 30. He will be in eastern # and will cross the line into op and return again into H at the close of the year. At no time will he be near any bright stars for which he might be mistaken. His wonderful ring system will be best seen during the summer months.

Uranus will be brightest July 16 as an evening star, and then only faintly visible to the naked eye.

Neptune will be brightest as an evening star January 8. Both Uranus and Neptune are too distant and faint to be objects of general interest.

ECLIPSES, 1910. There will be four eclipses this year, two of the Sun and two of the Moon, as follows:

1. Total of the Sun, May 9, invisible in the United States, visible in the Southern Pacific and Indian oceans,

II. Total of the Moon, May 23–24, beginning on the evening of the 23d, and visible in North, Central and South America, except Alaska. Visible as follows:

Yakutat, Alaska, marks the eastern limit of the eclipse. Throughout Alaska west of Yakutat, and Hawaii, the sun will set more or less eclipsed. Begins, Honofulu. 3:45 p. m.; size, 1 digit.

She will then be in the constellation Cetus, the whale. Her motion will be westward past the stars in the head of the whale. The last of September she will be almost two degrees from the brightest star of the constellation. Menkar: early in November, five degrees north of Mira, the wonderful variable star. It will be interesting to watch her pass one degree north of Gamma Ceti on October 10, and Lour degrees north of Delta Ceti on the 13th. These stars are of the fourth magnitude or about two degrees brighter than Vesta. On October 28 Vesta will be on the meridian at midnight and about 47 degrees up from the southern horizon in latitude 40 degrees. She will not be well situated for visibility again until February, 1912.

Explanation of Signs. Aries. 8 Taurus. O Gemini.

O Cancer.

Cancer. Leo. m Virgo. ^ Libra. m Scorpio. I Sagittarius. Capricornus. Aquarius. Pisces. The place indicated for the planets is for the first, second, third, fourth and fifth Sundays of each month, in the order of the planets.

Note. -The Moon will "run high" from "Lowest” to “Highest," and "run low". from "Highest” to “Lowest.” The Full Moon will be highest of the year at meridian passage December 16 and lowest June 22. She will begin to run lower March 21 and decrease in altitude until June 22, and then increase ("run higher") until December 21, after which she will gradually get lower until June 22. This because the Full Moon must always be on the opposite side of the Earth from the Sun, and hence when the Sun is lowest in declination the Moon must be highest, and when the Sun is highest the Moon must be lowest. The difference between extremes being 57°or (23 42° +5°)x2, 5° being the inclination of the orbit of the Moon to the ecliptic.

gures in the table "Sidereal noon" following this note. Note whether the figures be 'Morn" or "Eve." If "Morn' and the sum is more than 12 hours, the result rill be evening of the same day; if "Eve" and the sum is more than 12 hours, he result will be morning of the next day. Having found the time of meridian assage, for the rising subtract and for the setting add the numbers opposite the ame of the star in the column headed "For Rising and Setting," observing the irections as to "Morn" and "Eve,” as given a bove. Those stars marked

in he last column are circumpolar and do not rise or set in the latitude of New York ity. Stars having an asterisk (*) in the last column are only to be seen in the far outh and when near the meridian, as the vapors of the horizon will obscure them t rising and setting.

To tell how high up from the nearest point of the horizon a star will be at its neridian passage, subtract the declination of the star from 90°, and if the result is ess than the latitude of the place of the observer that star will neither rise nor set, ut is circumpolar, and the difference between that result and the latitude shows the tar's altitude above the north point of the horizon or below the southern horizon. Or, (90° -- dec.) -latitude = altitude or elevation of the star above the nearest point f the horizon at meridian passage for stars of a south declination. Examples: idereal noon, November 4.... ...... 9 06 p. m. Fomalhaut in meridian" column..... 22 48

3 54 p. m. = Time of rising.

11 54 p. m, = Time of setting. Declination of Fomalhaut = 30° south; therefore 90° -30° = 60° -40° = 20° Ititude of Fomalhaut in latitude 40° north at the time of the meridian passage of hat star. To measure celestial distances with the eye, keep in mind that one-third f the distance from the zenith to the horizon is 30°. For smaller measurements use he "Pointers" in the "Big Dipper,” which are nearly 5° apart-a convenient celestial init because always in sight. The "Yardstick" or "Ell and Yard" in Orion, or the 'Kings,” is just 3° long, or 142° each way from the central star (see Star table). Vhen the declination of a star is such as to bring it nearer to the zenith than to the Jorizon at meridian passage, use its zenith distance to locate it. The difference etween latitude and declination = zenith distance. If declnation is greater than latiude. such difference is to be counted northward (otherwise southward) from zenith.
