What we have now to consider is the value of this Natural Beauty. A region may be flat or mountainous, dry or wet, barren or fertile, useful or useless for either political or commercial purposes. But it is not its flatness or ruggedness, or its utility or inutility for political or commercial purposes, that we may find in the end is the most noteworthy characteristic, but its beauty--its own particular beauty. The conventional gold or oil prospector, or railway engineer, or seeker for sites for rubber or coffee plantation, or pasture-lands for sheep and cattle, may not bother his head about the beauty of the forests, the rivers, the prairies, and the mountains he is exploring. He is much too absorbed in the practical business of life to be distracted by anything so fanciful--as he thinks. Yet even he does see the beauty, and long afterwards he finds it is that which has stuck most firmly in his mind. And when he has unthinkingly destroyed it, future generations lament his action and take measures to preserve what remains. Advertisements, also, show us daily that nearly all countries--and it seems more especially new countries like Canada and New Zealand--regard Natural Beauty as one of their most valuable assets. And the reason why the Natural Beauty of the Earth is deemed so valuable a characteristic of its features is not hard to understand when we come to reflect. It is because Beauty is a quality which appeals to the universal in man--appeals to all men for all time, and appeals to them in an increasing degree. It is something which all men can admire and enjoy. And the more they enjoy it the more they want to get others to share in their enjoyment. Also the more Natural Beauty they see, the more, apparently, there is to see. Poets in their poems, and painters in their pictures, are continually pointing out to us less keen-sighted individuals new beauties in the features of the Earth. The mineral wealth of the Earth has its limits; even the productivity, though perennially renewed, is not unbounded. But the Natural Beauty is inexhaustible. And it is not only inexhaustible: it positively increases and multiplies the more we see of it and the more of us see it. So it has good claim to be considered the most valuable characteristic of the Earth. And if Beauty should prove to be its most valuable characteristic, it follows that knowledge of it is the knowledge about the Earth which is most worth having. It will certainly be the case that knowledge of other characteristics may be of more value to particular men for a special purpose for the time being. If an engineer has to build a railway, knowledge of the exact height above sea-level of various points and of the general configuration of the ground is of more value than knowledge of its beauty. But for the engineer himself, when he is not thinking of his railway, and for mankind in general, knowledge of the beauty may be the more valuable kind of knowledge.
