186 TANKS And wells of N.S.W., WATER SUPPLY AND IRRIGATION. these wells here and there point unmistakably to an older river system, overlaid by the present surface, would it not be better to look for it, and arrange our theory to fit the facts, and not the facts to fit the theory? In other countries it has been found advantageous to do so, for Professor Marsh, of America, says: "Hydrographical researches have demonstrated the existence of subterranean currents in many places where superficial geology had not suggested such a possibility. For example, the river Tiber, in Italy, loses suddenly a much larger proportion of the rainfall than can be accounted for by evaporation and the water flowing in the river; and Lombardine, than whom perhaps there can be no higher authority, satisfied himself that the quantity of water carried by these subterranean conduits and carried into the river is not less than three-fourths of the total delivery of the Tiber's basin. And we have reason to think it will be so here. To go no further than the Sydney water supply, what do we find? That rivers flowing through compact sandstone have yet running near them—that is, within two or three miles-springs which are little rivers in themselves. One such, found in the tunnel, is remarkable for the abundance of water which it furnishes. I will not detain you longer; but I think I have said enough to show that there is abundant room for investigation, and that a matter of such vital importance to the community ought to be taken up by a Royal Commission, or by some one with time and means at his disposal to carry out a complete investigation of the whole subject.
