The question thus raised is an interesting one, not to be dismissed in a word. Some force is given to it by the wide separation of the colonies from each other, and the lack of intercourse in the past. But anyone who watches colonial questions closely sees that great changes are taking place. Till a very few years ago Canada looked to Australia only eastward across the Atlantic and Indian Oceans. The Dominion has now become like Australia, a state upon the Pacific, with interests in that ocean which are sure to become very considerable. Lines of steamship, postal, and cable communication between the two countries are already in contemplation. The safety of such routes would of itself form a great common interest. Passing through the centre of the Pacific it would tend to create those national interests which would increase British influence in that ocean--an end very much in Australasian thought. On the Atlantic Canada is extending her trade relations with another group of colonies, the West Indies. This trade promises to develop greatly in the future, for as one country is in the temperate zone and the other in the tropics, each seems the natural complement of the other in range of production. The opening of a Panama route would give the Australian colonies a profound interest in the strength of the British position in the West Indies. {42} Australia and New Zealand, again, have a substantial interest in the political fortunes of South Africa, since in that country is the most vulnerable point of their most important trade route. In the _Naval Annual_ for 1890 Lord Brassey estimates the outward-bound Australasian trade which passes the Cape at twenty millions sterling per annum, and uses the statement to enforce his views as to the national importance of making perfectly secure our position at this great turning-point of the world's commerce. But I do not wish to lay undue stress upon these facts, which are only intended to be illustrations of the existence and growth of common interests between different groups of colonies. They are suggestions of future possibilities rather than powerful factors in the present.
