[November 1, 1890. 



Decl. + 23°. The radiant point rises about a quarter past 

 10 P.M. The Andromi'di's occur on the 27th, the radiaut 

 point being in R.A. Ih. 40m. Decl. + 43^ The radiant 

 point, which is circumpolar, souths at 91i. 13m. p.m. 



The moon enters her last quarter at 4h. 13m. p.m. on 

 the 4th ; is new at Ih. 38m. p.m. on the r2th ; enters her 

 first quarter at Oh. 45m. p.m. on the 19th, and is full at 

 111. 23m P.M. on the 26th. There will be a partial 

 eclipse of the moon on the afternoon of the 26th, but as 

 it is invisible in this country, and as only the two thou- 

 sandth part of the lunar disc will be obscured by the true 

 shadow, no further details need be given. The 7th mag- 

 nitude star ,5 Geminorum will disappear at 6h. 59m. 

 AiM. on the 1st (three minutes after sunrise) at an angle 

 of 145° from the vertex, and reappear at 8h. 4m. a.m. 

 at an angle of 296° from the vertex. The 6th magni- 

 tude star 42 Leonis will disappear at 3h. 2m. a.m. on the 

 6th at an angle of 340° from the vertex, and reappear 

 at 3h. 46m. a.m. at an angle of 267° from the vertex. The 

 5i magnitude star 39 Ophiuchi will disappear at 41i. 33m. 

 p.m. on the 14th at an angle of 138° from the vertex, 

 and reappear at 5h. 34m. p.m. at an angle of 267° from 

 the vertex, the moon having set at Greenwich at the time. 

 This is a very pretty double star, the components being of 

 5| and Ih magnitudes, and 12" apart. The colours are 

 orange and blue. At 5h. 3m. p.m. the same evening the 

 7th magnitude star B.A.C. 5831 will make a near ap- 

 proach to the lunar limb at an angle of 203° fiom the 

 vertex. At 4h. 42m. p.m. on the 18th the 5^ magnitude 

 star 33 Capricorni will disappear at an angle of 148° fi'om 

 the vertex, and reappear at 5h. 35m. at an angle of 246° 

 from the vertex. The 5th magnitude star 33 Piscium will 

 make a near approach to the lunar limb at 3h. 43m. p.m. 

 on the 21st (in sunlight) at an angle of 171° from the ver- 

 tex, and the 5i magnitude star B.A.C. 17 will disappear at 

 5h. 59m. P.M. the same evening at an angle of 125° from 

 the vertex, and reappear at 7h. 5m. p.m. at an angle of 

 268°. The 6th magnitude star 26 Geti will make a near 

 approach to the lunar limb at Hh. 22m. p.m. on the 22nd 

 at an angle of 208° from the vertex, and at llh. Om. p.m. 

 the same evening the 6i magnitude star 29 Ceti will dis- 

 appear at an angle of 223° from the vertex, and reappear 

 fifteen minutes later at an angle of 250°. The 6| mag- 

 nitude star 35 Ceti will disappear at Ih. 6m. a.m. on the 

 23rd at an angle of 177 ' from the vertex, and reappear at 

 2h. 2m. a.m. at an angle of 312°. At 7h. 25m. p.m. on the 

 24th the 5th magnitude star 38 Arietis will make a near 

 approach to the lunar limb at an angle of 176° from the 

 vertex. The 7th magnitude star B.A.C. 2154 will dis- 

 appear at 2h. 37m. a.m. on the 29th at an angle of 58° 

 from the vertex, and reappear at 3h. 34m. a.m. on the 

 28th at an angle of 343°. The 6i magnitude star B.A.C. 

 2514 will disappear at 6h. 27m. a.m. on the 30th at an 

 angle of 148° from the vertex, and reappear at 7h. 25m. 

 A.M. at an angle of 271° from the vertex.

THE TURN-UP CARD. 



BEGINNERS cannot be too often reminded of the 

 great importance of remembering the turn-up 

 card. Really good players often err in this re- 

 spect, and even though they do not actually 

 forget the trump card, neglect opportunities of 

 fine play afforded by the information that may be given by 

 means of it. 



In many cases the dealer may be enabled to inform his 

 partner of the position of trumps by playing a higher 

 card instead of the turn-up. Of course he must be care- 

 ful that his partner will not mistake the motive, as for 

 example, by tliinking that he is echoing when he has only 

 three trumps. 



An illustration is furnished by the following hand, 

 which also shows how a player whose hand on paper 

 appears hopelessly bad may by his skill in placing cards 

 be the means of saving the game. 



Z's Hand. 



Score — Three all. 



Z turns up the 4 of diamonds. 



Note. — A and B are partners against Y and Z. A has 

 the first lead ; Z is the dealer. The card of the leader to 

 each trick is indicated by an arrow. 



-AB, 1 ; YZ, n. 



YZ, 0. 



Note. — From his lead, A has not more than four clubs. 



Trick 3. 



Thick 4. 



<> 



-n\ 





B 



7ViV/!-,f— AB, 2; YZ, 1. 



B 



Tricks— AB, 2 ; YZ, 2. 



Note. — 3V/c7i- 3. — Y has conii)leted a call. Z can count 

 the spades in the respective hands. B's lead of the 7 was 

 obviously the penultimate, so that he has three cards of his 

 suit remaining. The three is marked in A's hand, and he 

 can have no more, as otherwise he would have led spades 

 in preference to a weaker four suit (see Tricl- 1). There- 

 fore Y has two spades remaining, and if B holds a ten ace 

 over him, which is likely, Y must lose both his spades, 

 if A leads through him. Z is bound to respond to his 

 partner's call, but if Y goes on with trumps Z will be 

 unable to ruff another spade. On this hypothesis, he 

 reasons that if Y has only five trumps to one honour A B 

 are almost sure to make two tricks in trumps and two 

 more in spades, and thus go out by honours. Z therefore 

 trumps with the seven and leads the eight, thus showing 

 Y that he has still a trump— the turn-up — and can trump 

 a spade, if Y wishes to give him another ruff.
