"There are Mountains on the Sea Coast of this Latitude, of an enormous Height and great Extent, called the Andes, the Tops and Sides of which are covered with everlasting Snow. These Mountains cast a Shade and Coolness round them, for several Leagues, and by their Influence it is, that the Climate is so temperate under that Part of the Line. But, says the Author, when we had sailed beyond the Æquator, into four or five Degrees of North Latitude, and were got out of the Influence of those Mountains covered with Snow, we then began to feel that we were near the Line, and the Climate was as hot as we could have expected to have found it at the Æquator itself." There can be no Doubt of the Truth of this Account: No Man would have made such Assertions as these, if they had not been true, when there were so many living Witnesses to have contradicted such an idle, needless Falshood as this would have been. And indeed the Appearance of wise Design in the Author of Nature is no where more conspicuous than in these Instances of his Care for the Preservation of the animal System. What could we have expected more than Mountains of Snow in Greenland? And even in those frozen Regions we have as great Instances of the same Providence: When the Springs are all frozen up, in that severe Climate, they have sometimes, even in the middle of Winter, such mild South Winds as serve to thaw the Snow, so as to cause Water to settle in the Valleys, and to run under the Ice in Quantities large enough to serve the Purposes of animal Life; not to mention the great Quantities of Timber which the Surf of the Sea brings upon that Coast, from other Countries; without which the Inhabitants would have no Firing, nor Timber for their Huts, nor Shafts for their Arrows, as there are no Trees in that Country. And now I hope it will not be thought too bold an Analogy if we presume to say, that as, contrary to all Expectation, at the Æquator (where intolerable Heat might be expected) the Inhabitants are provided with Mountains covered with Snow, to qualify their Atmosphere; why may not we suppose, that at the very Poles themselves there may be some Cause, unknown to us, which may render the Climate serene and mild, even in that supposed uninhabitable Part of the Globe? Why may there not be hot, burning Minerals in the Earth at the Poles, as well as snowy Mountains at the Æquator?
