at her dark limb at 12h. oOtu. at an angle from her vertex 

 of 216°. The second is on September 14, on the night of which 

 at lOh. 58m., 50 Sagittarii, of the 6th magnitude, will disappear at 

 the dark limb of the moon at an angle from her vertex of 13i° ; she 

 will tliough have sot prior to its reappearance. Thirdly, on the 

 16th, .SO Capricorni will disappear at her dark limb at yh. 47m. P.M., 

 at an angle of 12S° from the vertex of the moon, and will reappear 

 at her bright limb at Uh. Im. P.M. at a vertical angle of 28°. 

 Finally, on the 28th. before the moon rises, she will have occulted 

 f- Geminorum of the 4th magnitude. Its reappearance may be 

 observed later on at llh. 11m. P.M. at her dark limb, at an angle of 

 245° from her vertex. When our notes begin the moon is in 

 Gemini (" The Seasons Pictured," plate sxiv.), througa which she is 

 travelling until 2h. 30m. P.M. on tlie 2nd, at which hour she enters 

 Cancer. She remains in Cancer until 4h. A.M. on the 4th, and then 

 passes into Leo. Her journey through IjCo occupies her until 

 6h. P.M. on the 6th, when she crosses into Virgo (" The Seasons 

 I'ictured," plate sxv.). It is not un'il 7h. P.M. on the 0th that her 

 passage through this great constellation is completed, and she has 

 entered Libra (" The Seasons I'ictuied," plate xjvi.). Travelling 

 over Libra she arrives at llh. 30m. A.M. on the 11th on the 

 western edge of the narrow northern spike of Scorpio, which she 

 has crossed by Sh. 30m. the same evening and emerged in Ophiuchus. 

 She leaves Ophiuchus at 9h. A.M. on the 13th, and enters Sagittarius. 

 There .she remains until 5 P.M. on the 15th, when she leaves it in 

 turn for Capricornus (" The Seasons Pictured," plate xxi.). At 

 3h. 30m. P.M. on the 17th she quits Capricornus for Aquarius. Her 

 passage over Aquarius terminates at 4h. 30m. P.M. on the 19th, when 

 she enters Pisces (" The Seasons Pictured," plate xsii.). In 

 tlie course of her journey across Pisces she passes in'o a part of 

 Cetus at noon on the 20th, in which constellation she continues 

 until 7 P.M. on the 21st, re-emerging in Pisces at the hour last 

 named. It is only, however, to plunge into another outlier of Cetus 

 twenty-four hours later (i.e., at 7h. P.M. on the 22nd), and, when 

 she finally quits this at 8 A.M. on the 23rd, it is to come out in 

 Aries (" The Seasons Pictured," plate xxiii.). By 2h. P.M. on the 

 24th she has traversed Aries, and quitted it for Taurus. In the 

 course of her journey through Taurus she arrives at 6h. 30m. P.M. 

 nn the 27th on the boundary of the most northerly poriion of Orion. 

 It takes her until 2h. 30m. A.M. on the 2Sth to cross this, and when 

 she has done so she comes out in Gemini (-'The Seasons Pictured," 

 plate xxiv.). She passes out of Gemini into Cancer at llh. 30m. 

 p.ir. on the 29th. There we leave her at midnight on the 30th. 



A Rbmaukable Ride.— Mr. Chas. Hill, of the Fincbley Harriers, 

 on August 10, accomplished a remarkable ride on a " Geared 

 Facile " bicycle, having ridden no less than 293 miles in the 

 24 hours, only 2 miles less than the record standing to the credit 

 of Mr. G. P. Mills, and 21 miles more than all other previous per- 

 formances. This splendid ride, on tlie hottest day we have had this 

 year, is a great performance for both man and machine, more 

 especially in view of the fact that Jlr. Hill had only ridden a 

 " Facile " for a month previously to the start. He rode the same 

 machine throughout — a 46-inch, geared to 69 inches, weighing 

 about 36 lbs., and is quite confident that with all circumstances 

 favourable he can cover over 300 miles in 24 hours on a " Geared 

 Facile," of which he speaks in the highest terms.

NOTES. 



It will be seen on a careful 

 study of the irosition that for 

 full success A and B must make 

 one trick by ruffing Clubs, while 

 Y and Z must be prevented 

 from making Trumps by ruffing. 

 Further, either Z must be com- 

 pelled to lead Spades after the 

 Ace is out, or Y to lead a Diamond 

 after Ace is out and Trumps are 

 exhausted. Everything then de- 

 pends on rightly placing the 

 lead when Y's and Z's trumps 

 are out. By the line of play 

 indicated above A and 1! clear 

 out the Clubs from Y-Z's hands, 

 so that every lead must now 

 necessarily be from Diamonds or 

 Spades when Trumps are out. 

 Jloreover, by leading the Spade 

 Ace at trick 5, A clears Y of 

 ,11 Spades also. Note the effect of 

 "■ omitting this lead. Y covering 

 the Heart Nine will lead a small 

 Diamond, which either A or B 

 must win. If A wins, he has no 

 better course than to lead Spade 

 Ace, following with a small one, 

 which Y will trump with the 

 (Jueen, after which, no matter 

 how B may play, Y-Z must make 

 two more tricks in trumps. 

 (The fame result must follow 

 if B wins the first round of 

 Trumps as actually played above ) 

 If B, on the contrary, wins, he 

 must then take out two rounds 

 of Trumps as his best chance; 

 and Y-Z will be able to get rid 

 of the load by leading a Spade, 

 and thus make a Spade or a 

 Diamond, besides two Trump 

 tricks. 



In fact, A has to lead out the 

 Spade Ace to prevent the lead 

 being forced into his hand ; and 

 B must, in like manner, lead 

 out, or get out (according to 

 Ills position) the Diamond Ace 

 before drawing the second round 

 of Trumps. Thus, if Y leads a 

 Trump at trick 7, B wins with 

 the Ace, leads Diamond Ace, 

 and then goes on as above with 

 Heart Knave. 



A and B make five by tricks. 



If, in tins variation, Y dis- 

 cards a Diamond at trick 7, B 

 wins the trick with Heart C, 

 tlien leads out in succession 

 Diamond Ace, Heart Ace, and 

 Heart Knave. On this, if Z at 

 trick 9 should throw Heart King 

 to the Ace, to allow Y to win 

 trick 10, then A must discard a 

 Spade instead of a Diamond at 

 trick 9. Otherwise the game 

 will run as before.
