Uranus, and a diagram of the conjunction, will be found 

 in the English Mchanic for March 23rd. 



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

 soon after sunset as possible. He sets on the 1st at 

 lib. 57m. P.M., with a northern declination of 20° 10', 

 and an apparent diameter of 2-5". On the 30th he 

 sets at lOh. 11m. p.m., with a northern declination of 

 20° 48'. A map of the small stars near his path will 

 be found in the EmiUsh Mechanic for December 29th, 

 1893. 



Shooting stars are fairly plentiful in April, the best 

 marked shower being that of the Lyrids, with a radiant 

 point in E.A. 18h. + 33°. The radiant point rises on 

 the evenings of the 19th and 20th, when the maximum 

 occurs, at about 6h. 27m. p.m., and souths at 4h. 8m. a.m. 



The Moon is new at 4h. a.m. on the Cth ; enters her 

 first quarter at Oh. 33m. a.m. on the 13th ; is full at 

 3h. 2m. A.M. on the 20th ; and enters her last quarter 

 at 3h. 20m. a.m. on the 28th. She is in perigee at 3h. 

 A.M. on the 11th (distance from the earth 229,280 miles), 

 and in apogee at 8h. a.m. on the 26th (distance from the 

 earth 251,330 miles). At 4h. 19m. on the 2nd the 61 

 magnitude star 29 Aquarii will disappear at an angle of 66° 

 from the north point (the star being below the horizon at 

 the time), and reappear at 5h. 27m. a.m. (10 minutes 

 before sunrise) at an angle of 252°. At 7h. 4m. p.m. on the 

 9th the 5^ magnitude star y} Tauri will disappear at an 

 angle of 67°, and reappear at 8h. 4m. p.m. at an angle of 

 278°. At ]0h. 54m. p.m. on the 10th the 6i magnitude 

 star B.A.C. 1746 will disappear at an angle of 92°, and 

 reappear at lib. 44m. p.m. at an angle of 273°. At 

 8h. 40m. p.m. on the 11th the 5i magnitude star 49 

 Aurigit will disappear at an angle of 76°, and reappear at 

 9h. 37m. P.M. at an angle of 305°. At lOh. 52m. p.m. on 

 the 12th the 6th magnitude star 76 (c.) Geminorum will 

 disappear at an angle of 111°, and reappear at lib. 49m. 

 P.M. at an angle of 286°. At 8h. 42m. p.m. on the 16th 

 the 4 th magnitude star a- Leonis will disappear at an angle 

 of 78°, and reappear at 9h. 29m. p.m. at an angle of 357°. 

 At 4h. 28m. a.m. on the 19th the 6th magnitude star 

 B.A.C. 4394 will disappear at an angle of 106°, and 

 reappear at 5h. 25m. a.m. (the star being below the 

 horizon) at an angle of 306°. At 3h. 2m. a.m. on the 29th 

 the 5th magnitude star k Capricorni will disappear at an 

 angle of 53°, and reappear at 4h. 13m. a.m. at an angle of 

 264°.

Dual after 1. 

 Also after 1. 



We congratulate the three solvers {not the leading 

 triumvirate) who discovered these duals. 



As explained fully in the February number, the dual 

 short mate does not count. 



Correct Solutions received from the following : — 



Eleven Points. — A. C. Challenger, E. W. Brook. 



Ten Points. — H. Holmes. 



Nine Points. — J. H. Christie, L. Bourne, Chat, Alpha, 

 B. G. Laws, Semper, Guy, W. T. Hur'ey. Kt. J. 



Six Points. — A Norseman. 



The correct keys were also sent by A. R., but un- 

 fortunately too late for competitive purposes. 



H. S. Brandreth. — Your solutions this month are pain- 

 fully incorrect. In No. 11. After 1. R to K8, KtxR; 

 2. BxKt, Q to E3 (!). In No. 12. After 1. Q to KB8. 

 PxR, Black has the better game, though White may 

 draw. In No. 13. After 1. Q to KB8, Black may play 

 almost anything except BxP, KtP x P, and of course 

 B to B4. 



H. Holmes. — In No. 11, we would suggest 1. ... K to 

 B5 in reply to 1. P Queens. If then 2. Q xQP, Q to R3. 

 Unless you can proce that your move solves the problem, 

 the deduction of one point for the incorrect claim must 

 hold good. 



^ Norseman. — In reply to (No. 11) 1. Kt to QKt7 

 P to Q3 looks a strong defence. The post-card 



referred to has not been received. 



A . R. — The adverse decision in your case seems neces- 

 sary, though much to be regretted. Your presence on the 

 " Jury " will be most desirable ; it is to be hoped, there- 

 fore, that with this end in view you will send solutions of 

 the remaining sis problems.
