Morning Stars.

Venus, after September 23.

Mars, till November 12.

Venus is brightest August 19 ard October 30: Mars, November 12; Jupiter, August 31; and Saturn, October 3. The following planetary conjunctions occur: January 23, Venus and Jupiter; February 20, Mercury and Jupiter: March 3. Venus and Saturn; March 15, Mercury and Saturn; April 1, Venus and Neptune; May 9, Mars and Jupiter: May 24, Mercury and Neptune; June 30, Mars and Saturn; July 8, Venus and Uranus July 30, Mercury and Uranus; August 14, Mars and Neptune; September 14, Mercury and Uranus; September 26, Mercury an1 Venus. The greatest eastern elongations of Mercury take place March 29, July 27 and November 20; its greatest western elongat ons are: January 16, May 14, September 9 and December 28. Venus is at her greatest eastern (longation July 16, and at her greatest western elongation December 4.

Eclipses of Jupiter's Satellites.

The Eclipses of Jupiter's Satellites have been carefully calculated and the times of their disappearance and reappearance set down in the National Ephemeris. They are useful in furnishing local time where the longitude is known, or the longitude where correct local time is known. In the following table are given the phases of the eclipses visible here, with the Washington mean time of their occurrence. Between conjunction and opposition the shadow of Jupiter lies to the west or right of the planet (by direct vi ‹ion), where the phenomena should be looked for. After oppos tion the satellites disappear, and reappear on the east or left-hand side of the planet.

The satellites are marked in the usual way, by the Roman numerals I, II, III, IV; D

means disappears; R, reappears.
