Horotiu is seventy-eight miles south of Auckland, and the railway-station 

 there is 78 ft. above sea-level. Four separate bores were sunk in the hope 

 of discovering workable coal-seams. They were located at spots generally 

 about 20 ft. below the level of the railway-station. Bores I and II reached 

 a depth of 446 ft. and 450 ft. respectively. The latter ended at an old 

 beach formation filled with well-preserved marine shells. The data given 

 below belong to Bores III and IV, which were put down on Mr. Gallagher's 

 land. Bores I and II gave off abundant inflammable gas, and also threw 

 up|water at a high pressure.
