472 TRAVELS OF A NATURALIST 



But just as we rejoiced in this, the lad heaving the 

 lead sang out, ' By the mark two ' (fathoms), and again 

 we were bewildered. 



The course was mid-channel, as marked on the chart, 

 yet it was only 12 feet, and shoaled to the east and 

 deepened to the west, instead of vice versa. The fact
