ENGINEERING-WORKS IN NEW ZEALAND. 



Engineers and others who are interested in public works and other 

 undertakings will find inspection of many works throughout the 

 Dominion of considerable value. To such, attention is directed to 

 the undermentioned : 



Auckland. In and around the city there are the city drainage- 

 works, which are on the combined system, with discharge into the 

 ebb tides of the outer harbour ; city electric tramways, a feature 

 being a few of the steep grades ; city water-supply, with the new 

 Nihotapu Reservoir ; city concrete streets, the first constructed on 

 a large scale in the Dominion ; destructor, dealing with household 

 garbage ; Graf ton reinforced-concrete arch bridge. Of the Harbour 

 Board's works the reinforced-concrete wharves, the tide-deflecting 

 moles, electric cranes, reclamations, and the dry dock are particularly 

 interesting. 



Napier. The successful construction of a harbour on an open 

 coast in the presence of drifting shingle is well illustrated by the 

 outer breakwater. The long reinforced-concrete bridge carrying road 

 and railway across the Inner Harbour is a work worthy of a visit. 



New Plymouth. The development of a harbour in face of a large 

 littoral sand-drift is a lesson in such work. The oil-wells should not 

 be missed, nor the fine asphalted country roads. 



Wanganui. Attention is directed to the harbour-works, the 

 bridges over the river on which the town stands, and particularly 

 to the passenger-lift giving access to the higher levels of Durie's Hill. 



Wellington. In and around the City of Wellington the hilly 

 country has required the development of many interesting works, 

 of which the following may be pointed out : Sewage drainage of the 

 low-lying parts by the Shone system, the compressed air required 

 being derived by power obtained from the destructor ; the general 

 gravitation system with sea outfall, and minor district systems with, 

 septic tanks ; city water-supply, with the main reservoirs at Karori 

 and Wainui, and subsidiary reservoirs in the city, those at the high 

 levels being fed by electrically operated, multistage, centrifugal pumps ; 

 tunnels for roads and tramways passing through ridges at Seatoun, 

 Karori, and Hataitai, the last for tramway traffic only ; electric tram- 

 ways, particularly the hill systems ; the cable tramway to Kelburn. 

 The recently introduced municipal milk-supply should be studied. 

 The development of the storage and handling of exports and imports 

 on the wharves will be found to be a useful study ; also the Pipitea 

 reinforced-concrete wharf, the patent slip, and the boat-harbour. On 

 the railways, the Rimutaka incline, of i in 15, operated by the Fell 

 system of centre rail ; and the recently installed automatic electric 

 signals on both double and single lines may be seen at work. 



Christchurch. At Christchurch, the City of the Plains, may be 

 seen water-supply from artesian wells, and the pumping-station to 

 supply the reservoir ; sewage farm, sewage-pumping station, pre- 

 liminary-treatment septic tanks, refuse-destructor, electric tramways, 

 and street works.
