materially from those of Horsburgh and others, that an ex- 

 tract from his table is here subjoined.* 



From Johanna a north-north-east course will take a ship 

 clear of the Aldabra Islands ; after passing which a more 

 direct course may be shaped for Bombay. Supposing a 

 ship to have passed through the Mozambique between April 

 and September, the winds will generally blow from south- 

 south-eastward to the line ; as the latitude is increased to 

 the northward, the winds will veer to south-westward 

 Bound for Bombay, steer for the parallel of Kana^, and 

 then due east on that parallel till you make the island ; the 

 soundinas regularly decrease towards the island, which is 

 smaU,bSt easily known when the latitude is correctly as- 

 certained. As soon as Kanary is discerned, haul up to the 

 northward for the lighthouse on Colaba, which is often 

 seen through the haze before the land is distinguishable. 



Except in clear weather, very little use can be made of 

 the cross-bearings of land around Bombay harbour. Ka- 

 nary, the Ughthouse, and the Fair^vay buoy are the be^t 

 leadin<T marks for the harbour's mouth, which is formed by 

 TuU-reef on the starboard, and the Prongs on the larboard 

 hand going in. As soon as a ship is seen from the hght- 

 house a pilot is sent out; but it must be observed tha 

 neither a boat nor bris can work out agamst a flood-tide and 

 strong monsoon. BSmbay harbour is very ^^cure in a 1 

 weathers, being nearly land-locked. The islands of Sal-
