decided to use timber principals etc. for reasons of

economy. You will note that I am keeping the posts well back from the edge of the platform face and in order 204 not to have the rain beating in on to the platform between the carriage roof and the eaves of the platform roof it would be necessary to carry the platform roof well beyond the platform edge or just over the centre line of the line of rails. This I found very difficult to cantilever out in timber so I carried the roof right over the whole carriage and had posts on the far side from the platform. An iron roof could easily he made project six feet, beyond the edge of the platform. The roof can be extended further down the platform if required.

5. The whole of the roof principals, posts and framing of building are to be of hard wood. The sides of buildings are to be of white pine weather boarding with match hoarding inside. The roof sheeting is to be of 22 guage galvanised corrugated iron. In order to deaden the sound of the rain I am putting 5/8 inch match boarding under the roof sheets nailed to the underside of the purlins The waiting rooms etc. are entirely indeperdent of the roof but the walling is fastened to the ports and bie beams of roof principals and stiffens the whole against wind pressure.

6.

I estimate the cost of posts, foundations, principals and all roof covering at $23,664 or 24,910 square feet at 95 cents per square foot. I believe an iron roof could be put up cheaper than this especially if advantage be taken of the possibility of cantilevering out the roof over the edge of the platform. The wooden purlins and match boarding costing 13 cents per square foot would be common to both designs. The iron roof would not require to cover the same area as 9 feet could be cut off from the outside for the length of platform or 210 feet on both sides as above stated. The total area to be covered would then be
