Saturn is an evening star in March, in the sense of 

 rising before midnight. On the 1st he rises at lOh. 39m. 

 P.M., with a southern declination of 11° 25', and an 

 apparent equatorial diameter of 9'1" (the major axis of the 

 ring-system being 41|" in diameter, and the minor 13"). 

 On the 12th he rises at 9h. 53m. p.m., with a southern 

 declination of 11° 15', and an apparent equatorial diameter 

 of 9-2" (the major axis of the ring-system being 42^'' in 



diameter, and the minor 13 J 



On the 22nd he rises at 



9h. 11m. P.M., with a southern declination of 11° 4', and 

 an apparent equatorial diameter of 9'3" (the major axis 

 of the ring-system being 42J" in diameter, and the minor 

 18i"). On the 31st he rises at 8h. 32m. p.m., with a 

 southern declination of 10° 52', and an apparent equatorial 

 diameter of 9-4" (the major axis of the ring-system being 

 43f" in diameter, and the minor 13j"). Titan is at his 

 greatest eastern elongation at lOh. p.m. on the 14th, and 

 8|h. P.M. on the 30th. lapetus is in inferior conjunction 

 on the 14th. During March, Saturn pursues a short 

 retrograde path in Virgo, to the north-east of X Virginis. 



Uranus rises at midnight on the 1st, with a southern 

 declination of 17° 23', and an apparent diameter of 3'8". 

 On the 31st he rises at 9h. 58m. p.m., with a southern 

 declination of 17° 15'. During March he pursues a 

 retrograde path in Libra, being very near the 6^ magnitude 

 star 26 Librse towards the end of the month. 



Neptune is an evening star, and is still well situated for 

 observation. On the 1st he sets at 2h. 14m. a.m., with 

 an apparent diameter of 2-6", and a northern declination 

 of 20° 55'. On the 31st he sets at Oh. 14m. a.m., with a 

 northern declination of 20° 59'. During March he 

 describes a short direct path to the south-west of « Tauri. 



March is not a very favourable month for shooting 

 stars. 



The zodiacal light should be looked for after sunset in 

 the south-west during the absence of the Moon. 



The Moon enters her first quarter at Oh. 40m. p.m. on the 

 4th ; is full at 8h. 3Hm. a.m. on the 11th ; enters her last 

 quarter at 5h. 32m. p.m. on the 18th ; and is new at 

 lOh. 25m. A.M. on the 26th. She is in perigee at Ih. a.m. 

 on the lOth (distance fi-om the earth 223,220 miles), and 

 in apogee at 7h. a.m. on the 22nd (distance from the earth 

 251,960 miles). There will be a total eclipse of the Moon 

 on the morning of the 11th; magnitude of the eclipse 



(Moon's diameter — 1), 1-61. The first contact with the 

 penumbra takes place at Oh. 58m. a.m., with the shadow 

 at Ih. 54m. a.m. (at 127° from the northernmost point of 

 the limb towards the east) ; commencement of totality, 

 2h. 52m. A.M. ; middle of total phase, 3h. 39m. a.m. ; end 

 of totality, 4h. 27m. a.m. ; last contact with shadow, 

 5h. 24m. A.M. (at 69° towards the west) ; last contact with 

 penumbra, 6h. 20m. a.m. Sun rises 6h. 26m. a.m.

Communications for this column should be addressed to 

 C. D. LococK, Burwash, Sussex, and posted on or before 

 the 12th of each month. 



Solution of February ProhUm (A. G. Fellowes). 

 Key-move— 1. P to Kt3. 

 If 1. ... K to K4, 2. B to B6ch, or 2. Kt to K6, etc. 

 1. ... K to Kt6, 2. Kt to K6, or 2. Kt to B5ch, etc. 

 1. . . . K to K6, 2. E to K2ch, etc. 

 This problem appears to abound in dual or even triple 

 continuations. It seems unnecessary to print them all. 



Correct Solutions received from Alpha, J. T. 

 Blakeinore, N. Alliston, F. G. Ackerley, F. V. Louis, A. 

 Louis, W. Willby, E. W. Brook. 



Additional solutions of January problems have been 

 received from Beta (No. 1), J. M'Eobert (No. 2). 



Alpha. — It seems doubtful whether our solvers would try 

 a five-move problem. Three moves are, as usual, the 

 popular limit.- 



A. V. Challenger. — Many thanks for the problem, which 

 appears below. 



J. T. Blakemore. — Thanks. It shall appear next month. 



N. Alliston. — Key perhaps rather weak, but the problem 

 seems sound, and is marked for publication. 



7'". (r. Aekerley.— The whole of your solution is not quite 

 intelligible, but you evidently intend the correct key. 



We have received for review The Art of C/wss, by James 

 Mason (Horace Cox), price five shilUngs net. 



We have also received a collection of One Hundred Chess 

 Problems, by E. Orsini, one of the most prominent Italian 

 composers. The specimens, one of which is appended 

 below, range from two-move direct mates up to a seventeen- 

 move sui-mate.
