194 BIRDS OF NORFOLK. 



reed, one patch the very counterpart of the next, that 

 he should be able to remember the exact spot, but to 

 him it is easy enough from long habit and atten- 

 tion to nttle details. The broken head of a bull- 

 rush stem, in a hne with a small tree still further 

 back, gives him his " bearings," as surely as the " buoy," 

 just '^opening out" the steeple on the nearest head- 

 land, guides the course of the pilot over the track- 

 less sea. Eunning the boat close up to the bank, he 

 carefully parts the foremost reeds with his oar, and

 the result of such wondrous instinct. On once more 

 to that httle island, far out in the open stream, where 

 the heron rose on our first arrival. There most pro- 

 bably we shall find another nest, though very different 

 in size and structure. Eow gently then, and as we 

 approach the spot keep a sharp eye upon the fringe of 

 sedges by the water side. Surely she cannot have left 

 already ? No ! but see, she is off at last, though only that
