Continental shelf

“ The continental shelf is the gentle slope which extends from the edge of the land to a depth usually about 100, though in some cases as much as 300 fathoms, and is there demarcated by an abrupt increase in the steepness of the slope to ocean depths. In the deep sea two types of feature are recognized under the general names of depression and elevation. ”

“ The trade will give immense and profitable employment to our shipping. From the Cape of Good Hope to the Mediterranean, from the Atlantic to the Red sea and the Indian ocean, Africa is tropical or semi-tropical. She has most of the products of the East and West Indies. She can produce cheaper and better cotton than any other region, except our Southern States, to which, from their fertile soil, and climate favored by the Gulf Stream, free white labor will eventually give us, substantially, a monopoly of that great staple. She equals any country in the production of sugar, coffee, and cocoa. ”

“ The import of continental wool is on the decline, while that of colonial is largely increasing. At the late rate of progress, our vast woollen industry in this country will ere long be sufficiently supplied by the home and colonial produce. ”

“ At the time of signature, ratification or accession, any State may make reservations to articles of the Convention other than to articles 1 to 3 inclusive.
2. Any Contracting State making a reservation in accordance with the preceding paragraph may at any time withdraw the reservation by a communication to that effect addressed to the Secretary-General of the United Nations. ”

“ Northwestern Europe has become a great factory, drawing its food supplies and raw materials from distant parts of the world, and exporting manufactured products in exchange. Beside Europe stands the continent of North America, supplying in large part the needs of its own people for manufactures, and producing a surplus for export. North America, indeed, stands in one aspect above Europe, for it has unexhausted stores of natural resources which it lavishes on other parts of the world less richly endowed. ”

“ Commanding both sides of the Pacific, and the available coal-supplies on each, we command the ocean that, according to the old prediction, is to bear the bulk of the world's commerce in the Twentieth Century. Our remote but glorious land between the Sierras and the sea may then become as busy a hive as New England itself, and the whole continent must take fresh life from the generous blood of this natural and necessary commerce between people of different climates and zones. ”

“ In various lines of manufactures and of artistic goods we are still unable to compete. While east and west trade will no doubt continue indefinitely, for natural products it would seem that the chief exchange should be north and south, a difference in latitude causing variety in climates, and a diversity in productions both animal and vegetable. ”

“ The soundings and dredgings of which I have spoken enable us to make a tolerable map of the ocean beds and to describe their features. All the continents are bordered by a shelf reaching out under the shallow shore-water to a greater or less distance, and then dropping, usually with much abruptness, to the ocean trough. This shelf, perhaps originally a part of the primeval continent, bears most of the great islands near continents, such as Newfoundland, the West Indies, Great Britain and Ireland, Madagascar, the Aleutian, Japanese, and Philippine groups, the Malay Archipelago, and others. ”

“ Here again insularity and contracted area do their work of compressing population.
The causes of this insular density of population are not far to seek. Islands can always rely on the double larder of land and sea. They are moreover prone to focus in themselves the fishing industry of a large continental area, owing to their ample contact with the sea. Shetland is now the chief seat of the Scotch herring fishery, a fact which contributes to its comparatively dense population. The concentration of the French export trade of Newfoundland fish in little St. ”

“ The far eastern trade absorbs the excess production of Japan. In South Africa and Australasia, production nearly equals demand. In Canada, although the industry has been growing very rapidly, the demand still exceeds production. In South and Central America, Mexico and the West Indies, the demand is considerable and will probably increase; production has thus far been insufficient. ”

“ Coming down in our survey to the coast we come upon ground familiar to you all, and you all know how large a trade already exists with China and Australia in wood, and how capable of almost indefinite expansion is this commerce. Your forests are hardly tapped, and there are plenty more logs, like one I saw cut the other day at Burrard Inlet, of forty inches square and ninety and one hundred feet in length, down to sticks which could be used as props for mines or as cordwood for fuel. ”

“ What does matter is that North American manufacturers should continue to be supplied in vast and increasing quantities with South American hides for the use of leather manufactories; with ivory nuts for the button industry; with the coffee that cannot be grown in northern climes; with rubber and fibres and tannin materials; and with the minerals that exist in the sands and rocks of South America in unexampled variety and which can be there produced at half the cost that North America is forced to pay for labour. ”

“ Every trade must be important to Great Britain which will absorb manufactured goods and furnish raw material in return. Mercantile interests on the eastern coast might therefore quickly be advanced by increasing the wants of the natives, and then instructing them in what manner those wants may be supplied, through the cultivated productions of the soil. ”

“ Lastly, colonization can make no progress unless it finds markets on which it can put its produce. Up to the present western Europe has been the chief market for the wool, leather, meat, and cereals of the Pampean region; tropical America absorbs part of the output of the saladeros, flour, and dry fodder; and North America has recently begun to compete with Europe for wool, leather, and frozen meat. ”

“ When the opening and development of the Atlantic trade deprived the Mediterranean ports of their pride of place, an Atlantic stage of world-commerce began, in which England, an island with good harbours on its western coasts, was in the most favourable position. The Pacific stage which is now beginning must inevitably give the primacy to America. We had also a long start, industrially, over all our rivals, and our possession of great coal-fields and iron-fields close together gave us a still further advantage. Our labour was then cheap and good; our manufacturers capable and energetic. ”

“ Maritime peoples of small geographic base have a characteristic method of expansion which reflects their low valuation of area. Their limited amount of arable soil necessitates reliance upon foreign sources of supply, which are secured by commerce. Hence they found trading stations or towns among alien peoples on distant coasts, selecting points like capes or inshore islets which can be easily defended and which at the same time command inland or maritime routes of trade. ”

“ From Russia, the Danube Valley, Canada, Australia, Brazil, Argentine and many parts of Africa, new supplies of raw material are secured. Fresh sources are also discovered for the production of fodder, flax, cotton, wool and ores. It is an equilibrium, forever destroyed and forever re-established, between an increasing number of industrial nations with increasing populations and new agricultural bases, upon which the superstructure of the world's export industry is reared. ”

“ The world wants, on the other hand, the long list of lowland tropical exports which torrid America furnishes as yet in inadequate amounts, owing to the lack of an industrious and abundant lowland population. Commerce will eventually experience a readjustment in these localities to the natural basis of tropical production; but how soon or how effectively this change will take place depends upon the question of immigration of foreign tropical peoples, or the more difficult problem of white acclimatization.1425

“ It is common for two portions of a nation to exchange far less than do two portions of entirely different nations. The great territorial divisions of industry are determined first and mainly by differences of climate, soil, and natural resources. Thus trade arises easily between north and south, between warm and frigid climes, between new countries and old, between regions sparsely and regions densely populated. Foreign trade with distant lands is as old as history. ”

“ To-day, in America, there is one manufacturer, [Pg 219] and perhaps more, who is reviving some of the original forms and producing pewter reproductions which are being put on the market as such. For the modern colonial dining-room these are especially attractive, serving in every particular the purpose of decoration, but to the collector they are of no interest.
America boasts of several fine collections of this ware, especially in the New England states, where the chief ports for the trade were located. ”

“ The limitation of every enclosed or marginal sea lies in its small area and in the relatively restricted circle of its bordering lands. Only small peninsulas and islands can break its surface, and short stretches of coast combine to form its shores. It affords, therefore, only limited territories as goals for expansion, restricted resources and populations to furnish the supply and demand of trade. What lands could the Mediterranean present to the colonial outlook of the Greeks comparable to the North America of the expanding English or the Brazil of the Portuguese? ”

“ While people of the same latitude live approximately under the same temperature conditions, those of contrasted zones are subjected to markedly different influences. They develop different degrees of civilization, wealth, economic efficiency, and density of population; hence they give rise to great historical movements in the form of migration, conquest, colonization, and commerce, which, like convection currents, seek to equalize the differences and reach an equilibrium. Nature has fixed the mutual destiny of tropical and temperate zones, for instance, as complementary trade regions. ”

“ On the other hand, the forest species which contributed to the export trade during the early period of the occupation have lost their relative value, their products having to be brought from greater distances inland since the exhaustion of the supply from the woodlands on the coast. ”

“ As a favorable symptom, scattered location regularly marks the healthy growth of an expanding people, who throw out here and there detached centers of settlement far beyond the compact frontier, and fix these as the goal for the advance of their boundary. It is also a familiar feature of maritime commercial expansion, which is guided by no territorial ambition but merely aims to secure widely distributed trading stations at favorable coast points, in order to make the circle of commerce as ample and resourceful as possible. ”

“ From the unlimited supply of new land, colonies are especially fitted for a connection with Britain. Being in the opposite extremes of condition, they are in the highest degree mutually beneficial, the former affording the raw material in exchange for the more laboured products of industry of the latter, while at the same time the colonists are by habit great consumers of British manufactures. ”

“ It is beyond doubt, that so soon as an intelligent and laborious population is established there, this country will occupy an elevated rank in the commercial scale; it would form the entrepôt where the coasts of the great ocean would send their products, and would furnish the greatest part of their subsistence in grains to the north-west, to Mexico, to Central America, to Ecuador, to Peru, to the north coast of Asia, and to many groups of Polynesia--such as the Sandwich isles, the Marquesas, and Tahiti. ”

“ The percentage of the inhabitants engaged in building ships and in supplying the [46] ships' builders with forest and farm products was therefore very large. These forest and farm owners, as well as the shipyard hands and the crews of colonial vessels, helped to cultivate the sea habit among all the people. Then the farms were all within driving distance of navigable water; all farm surplus exported, either abroad or to other colonies, went in ships, and the farmer from the most remote plantation was not unlikely to see his produce loaded upon a ship of some kind. ”

“ In a few years, the fertility of the soil enables them to send surplus produce, in exchange for European or West India productions, to the stores of the country traders in some neighboring town, who, in their turn, transport it to the sea-coast, for home consumption or exportation. In this manner an active trade is maintained between the seaports and the interior, and as the new settlers stand in actual need of many foreign articles, which they require on credit, to be paid for from the next year’s crop, it follows, that the interior is invariably in debt to the merchants on the seaboard. ”
