4y6 HUMMOCK ISLAND. 



and a strong outset sweeping out of the bay round 

 the south side of the head, lessened the strain on 

 the cables. The sudden appearance of this breeze, 

 and the manner in which it was succeeded by 

 another from the westward, afforded additional 

 evidence of how necessary it is for anchorages in this 

 strait to be sheltered from both quarters. A jetty, 

 which has been run out by the Company, forms 

 available shelter at hi^h water for vessels of nine 

 and ten feet draught. 



On the 20th of January, having made a valuable 

 set of tidal* and other observations, and arranged 

 with Mr. Forsyth to meet him at Hobarton, we 

 sailed in the afternoon, and next morning passed 

 half a mile from the south side of the Pyramid, in 

 35 fathoms. It is a light-coloured mass, worthy 

 of its name, 300 feet high. From thence we steered 

 towards Cape Frankland, the N. W. point of 

 Flinders Island, which we had still to examine, 

 decreasing the soundings gradually to 26 fathoms 

 within two miles and a half to the W. N. W. of it. 

 We could see nothing of the sunken rock said to 

 lie' two miles west from the above headland; yet, as 

 we have not exactly gone over the spot, it has been 

 marked in the chart with a p. d. against it. I was 

 also anxious to obtain a distant seaward view of 



Hummock Island, highest part 400 feet, bearing S. E. 20 miles. 



* The time of higli water at the full and change is 1 Ih. 40m., 

 when the rise is 9 feet.
