(luwels were then eiiclused within tlie eyliiiders hefore uieiitioned, half 

 filled with concrete ready to receive the uprights. The uprights or 

 piles forming the lower portion of the vsuperstructure are of concrete 

 {li> ins. by 12 ins.) vertically reinforced with iuuv 1 [ in. steel bars 

 with horizontal hoopings of galvanised wire. Tiiey were also provided 

 with horizontal reinforcement for attachment to the lower beams. 

 These uprights were cast on shore and afterwards, when sutticiently set, 

 planted within the half-tilled cylinders, shored up, and concreted securely 

 in position. A\'hen the whole of the uprights were properly set the 

 reinforcement of the lower l)eams was then fastened to the attachments 

 before mentioned, boxed in and filled around with concrete. This 

 portion of the work, as well as fixing the cylinders, was most ditiicult, 

 owing to the periods of time between high and low water and heavy 

 seas being so short. 



After the whole of the above operations was completed the process 

 of building up the remainder of the superstructure was proceeded with 

 by attaching reinforcing systems to the ends of the vertical rods in the 

 uprights. This was then boxed in and enveloped in concretes to the 

 t(,>p of beam level. The decking, which is of concrete G ins. thick, re- 

 inforced with expanded metal of 9 ins. by 6 ins. mesh placed 1 in. 

 abo\'e the tensile side, was moulded upon the beams. >Steps and land- 

 ings of solid concrete reinfoi-ced and finished with a granolithic surface 

 were also built in. 



To join the new wt>rk with the old, two substantial piers, %\ ith 

 strong beams also reinforced with metal rods and wires, are built, to 

 which are attached tb.e iron braces and other members of the old part 

 of tlie jetty. 



The new portion (<i tlie jetty is railed ruund with a strong, but 

 light, iron railing, one side of which is made removable to facilitate 

 landing and shipping goods. A three-ton hand crane is fixed upon the 

 deck near the stairway, the beams being strengthened there for that 

 purpose. 



For the protection of boats lying alongside, the landing side and 

 end is faced witli fender pilings of timber. These can readily be re- 

 placed when the wood has become decayed. 



This work, originally estimated to cost the sum of £3000 by other 

 metliods, was actually completed departmentally for £2000. It has 

 been in use now for over a j'ear, and is in a most satisfactory ctmdition, 

 standing the shocks of heavy boats and occasional heaAV seas with little 

 \ ibration. 



77'p ••Htniy Ftitt Bridge'' acrost< tlie Koicie River. — This bridge, 

 the foundation-stone of which was laid by his Excellency the Governor 

 on the 1st September. 1906, is now nearing completion. It is intended 

 for ordinary country road traffic only, and is founded upon piles dri\en 

 into the sandy bottom of the river, and is the first example in this 

 country of a reinforced concrete bridge. The total length is 262 ft. 

 between abutments in nine clear spans of 28 ft. each, width of roadway 

 1.*^ ft. 6 ins., two sifle-walks of 3 ft. 9 ins. wide. 



The abutments are each founded upon seventeen reinforced con-
