_Father._ Men may venture out upon almost any sea except the largest as early as the beginning of April. For at the time when we date the sixteenth of March, the days lengthen, the sun rises higher, and the nights grow shorter. The north wind gently clears up the face of heaven with a light and cool breeze, brushes away the restless and storm-laden clouds, and with blithe persuasiveness asks for a new covenant. Then peace is renewed among the winds, for they all yearn for rest after the season of violent wrath and wearisome blasts; so they make a covenant once more in the way that we told earlier when we described the peace making. The showers cease, the waves sink to rest, the breakers flag, the swell of the noisy ocean dies away, all the storms weaken, and quiet follows upon restless turmoil. Now I have done as you requested: I have pointed out the seasons with definite dates both in spring and fall, when it seems most advisable to brave the perils of the sea. I have also informed you as to the times that seem more suitable for rest than for travel. I have likewise described briefly the sources of light in the sky and the belts that are drawn across the heaven, those under which travel is difficult and those which allow travel. And if you keep carefully in mind all these things that I have discussed with you, you will never be counted among the ignorant navigators, if you shall decide to try the trader’s calling. My advice, therefore, is first to fix in your mind all the facts which you have now heard; and later you shall have a chance to ask further questions, if you should wish to do so. ------------------------------------------------------------------------ XXIV INTRODUCTION TO THE SECOND PART: THE KING AND HIS COURT _Son._ The last time that I had a talk with you, sire, I heard a wise speech from your lips, one that should profit every man who intends to follow the craft with which our conversation was concerned. Since then I have meditated on that speech, and I believe that I have fixed firmly in memory most of the facts that were brought out at the time, whatever luck I may have later in trying to apply them. No doubt I ought, like everyone else, to observe carefully all the good which I have been taught; and more is to be expected from those who take thought than from those who forget. But whatever success or good fortune I may have in the practice, I delight to learn while I have the opportunity. Now I still have some subjects in mind which I wish to inquire about, but I am going to ask your consent to a discussion before I bring up the questions in which I am now interested; and when I have presented these, I shall await your answers.
