Aside from its importance to many branches of science, a knowledge of the oceans has a practical value for mankind. The intelligent development of our fishing industries, the laying of oceanic cables, the proper construction of harbor-works, oceanic commerce and navigation, as well as long-range weather forecasting, are all dependent on an understanding of the ocean.
Paul J. H. SchoemakerTo indicate how large a part of the Earth is covered by the oceans, we might call attention to the fact that a whole hemisphere, with its center near New Zealand, would have only one-tenth of its area as dry land! And the average depth of the seas is over two miles.
Paul J. H. SchoemakerWalking aft a few feet we stand at the steering gear of the ship. There is no cozy; wheel-house on the bridge for the quartermaster of a sailing ship! He must stand at the very stern, with an unobstructed view of the sails. When sailing "by the wind" his eye is glued to the weather-side of the uppermost sail; he keeps it drawing a trace of wind, but never lets it fill.
