Saturn is an evening star, rising on the 1st at 9h. 27m. 

 P.M., with a southern declination of 7° 1', and an apparent 

 equatorial diameter of 18|" (the major axis of the ring 

 system being 42" in diameter, and the minor 10"). Ou 

 the 12th he rises at 8b. 41m. p.m., with a southern declina- 

 tion of 6^ 46', and an apparent equatorial diameter of 18-4" 

 (the major axis of the ring system being 42^^" in diameter, 

 and the minor 10'). On the 31st he rises at"7h. 18m. p.m., 

 with a southern declination of 6° 15', and an apparent equa- 

 torial diameter of 18i" (the major axis of the ring system 

 being 42|" in diameter, and the minor 9J"). Titan is at 

 his greatest eastern elongation at 4h. p.m. on the 12tb ; 

 lapetus at superior conjimction at 4h. a.m. on the 20th ; 

 and Titan at greatest elongation at 2h. p.m. on the 28th. 

 Saturn describes a short retrograde path through a very 

 barren region of Virgo. 



Uranus is now an evening star, rising ou the 1st at 

 llh. 34m. P.M., with a southern declination of 16° 2', and 

 an apparent diameter of 3-8". On the 31st he rises at 

 9h. 30m. P.M., with a southern declination of 15° 51'. 

 During the month he pursues a short retrograde path in 

 Libra, to the E.N.E. of a' a- Libr^. 



Neptune is still an evening star, but should be looked for 

 as soon after simset as possible. He souths at 6h. p.m. 

 on the 1st, with a northern declination of 20° 35', and an 

 apparent diameter of 2-6". On the 31st he souths at 

 4h. 3m. P.M., with a northern declination of 20° 40'. 

 During the mouth he describes a short direct path in 

 Taurus. A map of the small stars near his path wiU be 

 found in the EwjUsh Mechanic for December 29th, 1893. 



There are no very well-marked showers of shooting stars 

 in March. 



The Moon is new at 2h. 18m. p.m. on the 7th ; enters 

 her first quarter at 6h. 28m. p.m. on the 14th ; is full at 

 2h. 11m. P.M. on the 21st; and enters her last quarter 

 at 8h. 28m. a.m. on the 29th. She is in apogee at 4h. 

 P.M. on the 1st (distance from the earth 251,620 miles), 

 in perigee at 6h. a.m. on the 17th (distance from the 

 earth 229,230 miles), and in apogee at noon on the 29th 

 (distance from the earth 251,130 miles). At 3m. past 

 midnight ou the 16th the 6j magnitude star to- Cancri 

 win be occulted at angle from the north point of 88°, and 

 will reappear at Oh. 37m. a.m. at au angle, of 314°. At 

 4h. 5m. A.M. on the 23rd the 1st magnitude star a Virginis 

 will disappear at an angle of 123°, and reappear at 5h. 16m. 

 A.M. at an angle of 297°. At Ih. 47m. a.m. on the 24th 

 the 6^ magnitude star B.A.C. 4700 will disappear at an 



angle of 109°, and reappear at 3h. Ini. a.m. at an angle of 

 318°. At 2h. 32m. a.m. on the 26th the 5th magnitude 

 star 2 Scorpii will disappear at an angle of 125\ and 

 reappear at 3h. 52m. a.m. at an angle of 282° ; the 6th 

 magnitude star B.A.C. 5255 will disappear at 2h. 58m. 

 A.M. at an angle of 130°, and reappear at 4h. 17m. a.m. 

 at an angle of 275°; at 3h. 6m. a.m. the 6th magnitude 

 star 3 Scorpii will disappear at an angle of 85°, and 

 reappear at 4h. 19m. a.m. at an angle of 320°. At 

 2h. 25m. a.m. on the 15th the 5th magnitude star 

 136 Tauri will make a near approach to the Moon's 

 southern limb, at an angle of 185°, the star being about 2' 

 away. On the 21st the 3^ magnitude star /3 Virginis 

 will make a near approach to the Moon's northern limb, 

 at an angle of 29°, the distance being about 2^'.

Unfortunately this dual occurs in the main variation. 

 " Chat " alone has discovered the composer's intention.

No. 9 is correctly solved by H. S. Brandreth, and No. 

 10 by Alpha. 



It is satisfactory to find that, in spite of the gaps caused 

 by Nos. 6 and 7, so many solvers are continuing the fight. 



With the exception that Mr. Adcock apparently retires, 

 and that " Chat " takes the seventh place, the positions of 

 the leading solvers are practically unaltered. 



M. Kaizer. — Thanks for the game, which you will find 

 below. 



L. Bourne. — We suggested, two months ago, defences to 

 the keys you give for Nos. 4 and 5 {vide January number). 

 It is therefore your turn to mate in two moves (if possible) 

 after those defences. If you cannot, the suggested key- 

 moves do not hold good. Black must be allowed to make 

 his best moves. 



Semper. — Apart from a curious key and defence to a 

 good "try," we do not remember any particular merit in 

 the problem you mention. Probably many solvers mistook 

 the " try " for the key.
