XOTES. 



(a) This can hardly be considered as good as 2. P to Q4. 



(b) To disengage his Queen's side, and make both Knight's 

 available for attack on the K's side. 



(c) This move gives Black time to develope his pieces. 



(d) If P to R3, then Kt to K4. Black has brought his pieces 

 vrell into play. 



(e) A very useful flank movement. The Queen now occupies a 

 good position. 



(/) With a view to playing R to B sq., which might give a 

 chance for B x RP. 



(3) Although tempting, this is weak, as the P will sooner or 

 later be captured. 



(h) If Black plays Q x Q. 26. QR x Q, B x P. 27. Kt x P. 



(j) To guard against Q to R5, also to double his Rook on the K's 



ae. 



(j) To bring the B into good play. 



(k) K to Kt sq. was the proper move. 



(I) To guard against P to KKt4. 



(m) Black now brings about the exchange of four pieces, re- 

 maining with a superior end position. 



(?i) If R X P White could equalise the game by playing 

 R to Q7 (ch), followed by R x P aud R to B7, &c. 



(o) This is playing Black's game. White ought to have played 

 R to B6 (ch), driving the K back agtiin. 



(p) A good move. It would be dangerous to take, as by K to 

 Kt3 and Kt4 White would gain a decisive advantage. 



(9) Now, of course, the game i."; virtually over, as White has but 

 the one square on B4 to defend his KP, and when short of a move 

 he will have to move his K. 



()•) Now comes the most extraordinary part of the game, which 



Whitb. 



should serve as a warning ihat a 

 game is never won until check- 

 mate is given. By playing P to 

 B4 Black wins, as the Hook's 

 Pawn becomes free to advance 

 whether White replies with P x 

 P or P to Kto. Instead of 

 winning the game on the move 

 Black lost it on the move by 

 ha.'itily advancing the wrong Pawn 

 without examining the conse- 

 ((uences. Besides losing the well- 

 earned victory in a hard fought 

 game. Black loses all chance to 

 play for first and second prize, 

 although this is the only game 

 lost out of eight games played. 

 (•') The game is not to be saved if Black plays P to R5 then 

 P X P, P to R6. P to Kt7 (it would be quite useless to plav the 

 K on account of P to KG) P to R7. P to KtS (Q), P to R8'(Q). 

 Q to QC (ch), K to B2. P to K6 (ch), K to Ki sq. Q to KtS (ch), 

 K to R2. Q to B7 (ch), K to Kt sq. Q to B7 (ch), K to R Bq. 

 Q to B6 (ch) and wins.

TuE EuMo.vi) Beds of BK.iziL. — The diamond beds of Bahia aucj 

 Minas Geraes, in Brazil, are very similar in character as regards 

 the minerals composing them and their plateau form, or situation 

 on watercourses. A new bed has been recently opened on the Rio 

 Purdo in Bahia, which presents some differences to those hitherto 

 known in Brazil. The country around is low and marshy, and 

 covered with forests. The working of these forests has led to the 

 discovery of the diamonds, which are found in a white clay along 

 with beds of decomposed leaves. The deposit appears of modem 

 formation. The minerals of the clay accompanying the diamond 

 are, according to JI. Gorceux, quartz, silex, monazite, zircon, dis- 

 thene, staurotede, grenat almandine, corindon, and some oxides of 

 iron. There are no oxides of titanium, or tourmalines, as is fre- 

 quently the case in diamond beds. The clay appears to be from 

 its character and situation the dthris of the granite mountains 

 bordering on the Bahia coasts. — Engineering.
