But before the chalk was tossed aloft there had been an earlier upheaval from the depths of the ocean, that of the Jurassic limestone. This was built up by coral insects working indefatigably through long ages, piling up their structures, as the sea-bottom slowly sank, straining ever higher, till at length their building was crushed together and projected on high, to form elevated plateaux, as the Causses of Quercy, and Alpine ranges, as the Dolomites of Brixen. But in the uplifting of this deposit, as it was inelastic, the strain split it in every direction, and down the rifts thus formed danced the torrents from higher granitic and schistous ranges, forming the gorges of the Tarn, the Ardêche, the Herault, the Gaves, and the Timée, in France. It has been a puzzle to decide which appeared first, the egg out of which the fowl was hatched, or the hen which laid the egg; and it is an equal puzzle to the anthropologist to say whether man was first brought into existence as a babe or in maturity. In both cases he would be helpless. The babe would need its mother, and the man be paralysed into incapacity through lack of experience. But without stopping to debate this question, we may conclude that naked, shivering and homeless humanity would have to be pupil to the beasts to learn where to shelter his head. Where did man first appear? Where was the Garden of Eden? Indisputably on the chalk. There he found all his first demands supplied. The walls of cretaceous rock furnished him with shelter under its ledges of overhanging beds, flints out of which to fashion his tools, and nodules of pyrites wherewith to kindle a fire. Providence through aeons had built up the chalk to be man's first home. Incontestably, the great centres of population in the primeval ages were the chalklands, and next to them those of limestone. The chalk first, for it furnished man with flints, and the limestone next when he had learned to barter. He could have lived nowhere else, till, after the lapse of ages, he had developed invention and adaptability. Besant and Rice, in "Ready-money Mortiboy," speak of Divine Discontent as the motive power impelling man to progress. Not till the chalk and the limestone shelters were stocked, and could hold no more, would men be driven to invent for themselves other dwellings. The first men being sent into the world without a natural coat of fur or feathers, would settle into caves or under overhanging roofs of rock, and with flint picked out of it, chipped and pointed, secure the flesh of the beast for food and its hide for clothing. Having accomplished this, man would sit down complacently for long ages. Indeed, there are certain branches of the human family that have progressed no further and display no ambition to advance.
