The collection of the land-snails alone would be no small tax. Seventy-four are peculiar to Great Britain: hence there must have been a hundred and forty-eight snails collected from that island. Six hundred species are found in Southern Europe alone, and twelve hundred must have been collected from there; eighty in Sicily, ten in Corsica, two hundred and sixty-four in the Madeira Islands, a hundred and twenty in the Canary Islands, twenty-six in St. Helena, sixty-three in Southern Africa, eighty-eight in Madagascar, a hundred and twelve in Ceylon, a hundred in New Zealand, and others on every large and some of the small islands of the globe. The world must have been circumnavigated many times before the vessel of Magellan was built, and every island visited and ransacked ages before the time of Captain Cook. But it seems surprising, since these voyages must have been performed by the sinful antediluvians, that they did not save themselves in their ships when the flood came; for vessels that could perform such voyages would certainly have survived the flood more readily than the clumsy ark. But was it really done? A thousand men in ten years, with all the appliances of modern art,--steamboats, railroads, canals, coaches, and express companies,--could not accomplish it in ten years; nor ten times the number of men keep all the animals alive in one spot for one year, if they were collected together. "But," says the Christian, "Noah never did collect them: no intelligent person in this day ever supposes that he did." What then? "The Bible expressly declares that 'they went in unto Noah into the ark.' By instinct, such as leads the swallow to take its distant flight at the approach of winter, they came from all parts of the globe to the ark of safety."
