WAIKATO RAILAVAY—ALTERNATIVE LINES AUCKLAND WHARF TO NEWMARKET. No. 2. Mr. Wrigg to Mr. Blackett. Sir, — Auckland, 15th August, 1871. I have the honor to transmit tracings of the plan and sections of the three alternate lines as surveyed from Newmarket to Auckland, with an approximate and relative cost of each. I have attached to the estimates such notes as appeared to me desirable for your information, and have only to add that the quantities have been taken out at the slopes noted on the section, and as if the ground in cross section was level. I am of opinion that the two small tunnels on the Coast Lino will be safe with timber lining, and that they could be executed at the price per yard I havo named, the material being beds of sandstone and indurated sand in horizontal layers, so that it is not probable that water will interfere with their construction. I have, &c, John Blackett, Esq., Acting Engineer-in-Chief, Henry Wrigg. Wellington.
