tho gas-tight joint. 2. They obviate the inconTenionce and danger 

 arising from manholes with open channels. 3. The effectual flush- 

 ing of the drain is secured, as the inside form or bore of thei:)ipe is 

 maintained throughout. 4. The seal of the cover cannot be broken 

 by heavy flushing, or by the drain getting stopped up. 5. The 

 form of the inspection aperture admits of the drain being readily 

 examined, and the cleansing rods being worked with ease through- 

 out. 6. The benching-up of the sides of the manhole chamber, and 

 the expense of an air-tight door, together with the ventilating pipe, 

 are dispensed with.

Black played 



P to B4 

 A sacrifice justified by the position. 



P to QR3 



P xKt 



Q to Kt5 



RPxP 



Q to K sq. 



Better than playing Q to R4; the Black K can only play to Q2 at 

 considerable inconvenience, as by P to KR3 White threatens to 

 take possession of K6 with his Q, when he shonld obtain a very 

 strong game. 



PtoKo 



P to R3 

 White pnrsnes his attack with determination. In spite of the 



result of this game, we believe that White, even after giving up 

 his second Knight, might have won. 



Qx Kt 



Q to KG (ch) K to Kt sq. 



Rto B3 

 This looked the best. Of course there is no reply to KR to R3 ; 

 but we think that the loss sho.vy move of B to K3 would have 

 won. The position is full of combinative possibilities. 



Kt (K2) xP 

 Black owes his escape to this move.

This is important, for if now P x Kt, Black threatens R to K 6(i.
