APPENDIX
CONTAINING THE COMPARATIVE POPULATION OF THE DIFFERENT QUARTERS OF OUR GLOBE.
[The numbers are given in Table III.]
§ 36. The Five principal parts of our globe, America, Europe, Asia, Africa and Australia are not equally thickly settled. Europe and Asia have, in proportion to their extent, the greatest population; America and Australia the least.—The following Plate, No. XV, shows the comparative population of these continents.
Fig. I represents the whole surface of land on our globe, inhabited by nearly One Thousand Millions (One Billion) human beings. If these were to live throughout as close together as inEurope, then they would only occupy a surface of land as large in proportion, as the inner circle markeda. But the two rings,bandc, occupy each as much surface as the circlea; hence there is yet room for twice as many human beings; before each quarter of the world is as thickly settled as Europe.
Fig. II representsAsiaand its population. If this quarter were settled as thickly as Europe is, then its inhabitants would only fill the inner circle markedb; the ringa, therefore, is still left for settlement.
Fig. III exhibits the population of Africa. If the inhabitants of this continent lived as close together as those of Europe, they would only fill the inner circle, markedc, and the surrounding ring might yet be inhabited.
Fig. IV shows the comparative population of America. Its inhabitants, crowded together as the inhabitants of Europe, would only occupy the small circlee; the whole broad ringf, therefore, is still left for settlement!!
Fig. V represents Australia. Its inhabitants, settled as in Europe, would only fill the circlea.
Fig. VI represents the population of Europe filling the whole of that Quarter.
The whole of these Six figures may represent to the pupil the comparative extents of the five great continents of our globe; but theinner circlesof these figures, and the whole of the sixth figure, show their comparative populations. From a close inspection of this plate the pupil may learn:
1. That the population of Asia is yet greater than that of all the rest of the world. (The circlebin figure II being yet larger than the inner circles of all the other figures, and figure VI taken together.)
2. That the population of Europe is as yet larger than that of America, Africa and Australia, taken together.
3. That the population of Africa is larger than the joint populations of America and Australia.
4. That America if once settled as Europe is, will have more than Six times her population.
