I trust that I have not kept you too long over these details. What I wish to impress upon you is that Hampshire is a county specially fitted for the study of important bio-geological questions. To work them out, you must trace the geology of Hampshire, and, indeed, of East Dorset. You must try to form a conception of how the land was shaped in miocene times, before that tremendous upheaval which reared the chalk cliffs at Freshwater upright, lifting the tertiary beds upon their northern slopes. You must ask--Was there not land to the south of the Isle of Wight in those ages, and for ages after; and what was its extent and shape? You must ask--When was the gap between the Isle of Wight and the Isle of Purbeck sawn through, leaving the Needles as remnants on one side, and Old Harry on the opposite? And was it sawn asunder merely by the age-long gnawing of the waves? You must ask--Where did the great river which ran from the west, where Poole Harbour is now, and probably through what is now the Solent, depositing brackish water-beds right and left--where, I say, did it run into the sea? Where the Straits of Dover are now? Or, if not there, where? What, too, is become of the land to the Westward, composed of ancient metamorphic rocks, out of which it ran, and deposited on what are now the Haggerstone Moors of Poole, vast beds of grit? What was the climate on its banks when it washed down the delicate leaves of broad-leaved trees, akin to our modern English ones, which are found in the fine mud-sand strata of Bournemouth? When, finally, did it dwindle down to the brook which now runs through Wareham town? Was its bed sea, or dry land, or under an ice sheet, during the long ages of the glacial epoch? And if you say--Who is sufficient for these things?--Who can answer these questions? I answer--Who but you, or your pupils after you, if you will but try? And if any shall reply--And what use if I do try? What use, if I do try? What use if I succeed in answering every question which you have propounded to-night? Shall I be the happier for it? Shall I be the wiser?
