From the time when the first bit of a wild beast's skin was hoisted by some pre-historic savage, thousands and thousands of years ago, nobody had learnt how to tack, that is, to sail against the wind. The only way any ship could go at all well was with the wind, that is, with the wind blowing from behind. So long as men had nothing but a single "wind-bag" of skin or cloth the best wind was a "lubber's wind," that is, a wind from straight behind. When more and better sails were used a lubber's wind was not the best because one sail would stop the wind from reaching another one in front of it. The best wind then, as ever since, was a "quartering wind," that is, a wind blowing on a vessel's quarter, half way between her stern and the middle of her side. Ships with better keels, sails, and shape of hull might have sailed with a "soldier's wind," that is, a wind blowing straight against the ship's side, at right angles to her course. But they must have "made leeway" by going sideways too. This wind on the beam was called a soldier's wind because it made equally plain sailing out and back again, and so did not bother landsmen with a lot of words and things they could not understand when ships tacked against head winds. Who first "tacked ship" is more than we can say. But many generations of seamen must have wished they knew how to sail towards a place from which the wind was blowing. Tacking probably came bit by bit, like other new inventions. But Fletcher of Rye, whom Henry always encouraged, seems to have been the first man who really learnt how to sail against the wind. He did this by tacking (that is, zigzagging) against it with sails trimmed fore and aft. In this way the sails, as it were, slide against the wind at an angle and move the ship ahead, first to one side of the straight line towards the place she wants to reach, and then, after turning her head, to the other. It was in 1539 that Fletcher made his trial trip, to the great amazement of the shipping in the Channel. Thus by 1545, that year of naval changes, the new sailing age had certainly begun to live and the old rowing age had certainly begun to die. The invention of tacking made almost as great a change as steam made three hundred years later; for it shortened voyages from months to weeks, as steam afterwards shortened them from weeks to days. Why did Jacques Cartier take months to make voyages from Europe and up the St. Lawrence when Champlain made them in weeks? Because Champlain could tack and Jacques Cartier could not. Columbus, Cabot, and Cartier could no more zigzag towards a place from which the wind was blowing dead against them than could the ships of Hiram, King of Tyre, who brought so many goods by sea for Solomon. But Champlain, who lived a century later, did know how to tack the _Don de Dieu_ against the prevailing south-west winds of the St. Lawrence; and this was one reason why he made a voyage from the Seine to the Saguenay in
