PORT SYDNEY. 73 
anyone at all acquainted with the present state of 
aeronautics knows that matters will be settled by “‘ bolts 
from the blue.”’ 
As to exposure tostorms. Our dangerous weather comes 
from S.E. to N.E. The S.E. seas run on to Manly and 
Dobroyd ; the N.H. seas are broken by North Head. The 
visible horizon of Port Sydney is «. by N. to N.EH. by 
E., and seas from this point are more or less broken up

embarked in galliots at the Fleet Ditch, now they enjoy 
the facilities of Tilbury. At Dover the rise and fall of 
the tide makes a vast difference in the quantity of work 
when we compare it with our insignificant five or six feet. 
Cherbourg and Colombo are also made ports. Galveston 
in the Gulf of Mexico has also done a lot of similar 
work to ours; and then we have the wealth of experi-

ways to profit by. 
Dr. Quaife described at length the freezing process for 
driving subways; it is an excellent method and enables 
us to penetrate any rubbish. As one of the speakers 
pointed out, it is delineated by Mr. Norman Selfe for found- 
ing the piers of his Great Sydney Bridge. Another speaker 
said he would prefer to use up-harbour frontages, but 
picture to yourselves the “* Lusitania”’ in Darling Harbour 
being turned end for end; and besides most of the fore- 
shores are cliffs and you have to carve out the wharf, and
