to develop water confined by dikes (pI. 1). It is not a Maui-type well because it is not based on the skimming principle. 'Yells de-veloping water from between dikes and not utilizing the skimming principle will hereafter be called the I~anai·type well. A plan and section of the well are shown in figure 14.

After excavating 242 feet on the incline through basalt and one dike, water with only 3 grains of salt per gallon (31 p.p.m.) was encountered at an altitude of 735 feet in a dense body of rock. The upper 4 feet of this rock is platy and vesicular and seems to merge into overlying scoriaceous basalt. The platy lava grades downward into columnar-jointed rock.
