The Planets. — Mercury is a inorniug star, baviug its 

 fjreatfst westerly elongation of 27 41' on the 17th, when 

 it rises about three-quarters of an hour before the sun. 



Venus is also a moruini: star situated in Aiiuarius. 

 She is at greatest brilliancy on the 21st, on which date 

 she rises about an hour and three-quarters in advance of 

 the sun. 



Mars is unobservable, being in conjunction with the 

 sun on the 30th at 1 a.m. 



Jupiter and Saturn are both morning stars, the former 

 in Caiiriccn-uus, the latter in Sagittarius, but as they only 

 rise about two hours before the sun, they are not well 

 suited for obser\-ation. 



Uranus is near the position indicated last month, about 

 1^ north of 4-1 Ophiuchi. He is in quadrature on thi- 12th. 

 and stationary on the 27th, rising on the latter dat'" about 

 (juartor past one a.m. The great southerly declination of 

 over 23*^ makes the planet somewhat unsuitable for 

 observing purposes. 



Neptune is the only planet that can be observed in the 

 evening. He crosses the meridian shortly after 7 p.m. at 

 the beginning of the month. He is making a short 

 loojx^ path in Gemini on the confines of Auriga, Taurus 

 and Orion ; this is shown by the diagram given last month. 

 The jdanet can be readily found from the triangle of stars 

 which has a double star for one corner almost 1' soutb of 

 1 Geminorum, and it is a little brighter than either of the 

 star pair referred to. The planet can also be picked out 

 by observations some few days apart, but this is becoming 

 more difficult since the planet is at the stationary point 

 on the 10th, after which the motion is again easterly. 



The Stars. — About the middle of the month, at 9 p.m., 

 the position of the principal constellations will be as 

 follows : — 



Zknith 

 South 



No britrht constellations in the zenith. 



Cancer and Hydra on the meridian ; Gemini 

 high up, Procyon and Siring, all a little to 

 the west. Orion is to the south-west, and 

 Irt'O {Rftjiihiit) to the south-east high up. 

 Wkst . Taurus, Aries nearly setting, Auriga (Ca^e//rt) 

 high up. To the north-west Perseus, also 

 Andromeda low down. 

 Virgo {Sjtica rising), Bootes {Ardurus). To 

 the north-east Ursa Major high up, Corona, 

 Hercules and Veija low down. 

 Polaris; to the right, Ursa Minor, Draco; 

 below, Cygnus, Cepheus ; to the left, Cassio- 

 peia, 

 ^linima of Algol -will occur on the 10th at 1.26 \.sx., on 

 the 12th at 10.14 p.m., and on the 1.5th at 7.3 p.m.

Of No. 2 only, from H. Myers. 



H. J/(/tcx.— After 1. R to B3 Black plays Kt to Kt4 

 and there is no mate. 



G. B. Davies. — In No. 1 you have overlooked that the 

 White Knight at B4 is " pinned " by the Black Bishop. 

 In No. 2, after 1. P to K7, Kt to QG or K7, White must 

 give check, as the Knight threatens to do the same. 



W. Jail. — Much regret to hear your news, and trust that 

 you will be able to compete when the new Solution 

 Tourney begins. At what date would you prefer your 

 year's subscription to Knowledge to commence. 



Whitchurch. — Your solution of No. 1 (January) was 

 received too late to acknowledge. After 1. Kt to K2cli, 

 Kt X B, 2. R to R.5ch is not mate, as the Kt can interpose. 



TF". /. AVen. — Yes, "three" was a misprint for '"foiu-." 

 Your suggested solution by 1. Kt to Kt6 was fully dealt 

 with last" month. Black saves himself by obtaining a 

 stalemate position, playing 1. ... P to R7, and 2. . . . 

 P to R8 (becoming a Bishop), while White has to block 

 the King's Pawn by 3. Kt to K-5. This device constitutes 

 tlie main idea of the problem, which is otherwise worthless, 

 except for the key.
