The limestone on ^Maidmans creek isthe nearest outcrop to the mouth of the estuary: it is distant 11 miles from SandyIsland and 22 miles from the outer Imoy. Considerable piles of loose limestone on the shore near the mouth of Doctorscreek may indicate limestone in place near the surface of the ground. The placeis not within reach of boats at present on account of the shallowness of the Avaterin front. At no point in estuary is there sufficient loose rock to be of any servicefor purposes of construction. 1913 IXYESTIGATIOXS AT .TAMILS BAY, 39. Landslides on Shores of Estuary.
