110 DISCUSSION. 



available, to which I should add, of suitable quality, within a 

 moderate distance so that the cost of the necessary works, whether 

 by gravitation, pumping, or a combination of these will not be 

 unreasonable, or at least fairly economical. With an abundant 

 supply of water available at a reasonable cost, a system of sewerage 

 and drainage can be readily designed. 



As to the relative merits of the rectangular and radial systems 

 of laying out the principal lines of communication : these have 

 been clearly dealt with, but it is impossible to deal with this matter 

 more definitely until the site of the proposed city is actually 

 selected. When this is done, I consider that the physical features 

 of the country will indicate the most suitable sites for the main 

 public buildings, and the most desirable combinations of the 

 rectangular and radial systems of streets connecting these impor- 

 tant buildings with the remainder of the city. Such cities as 

 Washington, Paris, Berlin, Vienna, and Budapest give valuable 

 suggestions on this head. 



The cardinal direction of rectangular streets in regard to the 

 latitude of the site has been very fully considered, and I do not 

 propose to add anything to this part of the paper, but in regard 

 to the width of the principal streets, I consider that there should 

 be ample room for a double line of tramway with a thoroughfare 

 on each side for vehicular traffic, and ample width for footpaths. 

 In the main street of the city leading up to the principal Govern- 

 ment buildings, I consider the plan adopted in the Unter-den- 

 Linden of Berlin would be most suitable, as it provides completely 

 for all kinds of traffic, and the rows of trees would be most useful 

 in summer, and add to the beauty of the street. Even George 

 Street near the Town Hall is not wide enough for the principal 

 street of a city such as Sydney. 



It must always however, be considered that very wide streets, 

 such as King William Street, Adelaide, involve considerable 

 expenditure in construction and maintenance, where the traffic is 

 heavy. There is a practical economical width which should be 

 obtained in every case wherever possible, which depends upon the
