Ned remained for a fortnight without any particular duties. When the prince was closeted with persons of importance, and he knew that there was no chance of his being required, he spent much of his time at his aunt's. He was beginning to feel weary of hanging about the prince's antechamber doing nothing, when one day a page came up to him and told him that the prince required his presence. He followed the boy to the prince's cabinet, full of hope that he was to have an opportunity of proving that he was in earnest in his offers of service to the cause of Holland. "I daresay you began to think that I had forgotten you," the prince began when the page had retired and the curtain had fallen behind him, "but it is not so. Until today I have had no occasion for your services, but have now a mission to intrust to you. I have letters that I wish carried to Brussels and delivered to some of my friends there. You had best start at once in the disguise of a peasant boy. You must sew up your despatches in your jerkin, and remember that if they are found upon you a cruel death will surely be your fate. If you safely carry out your mission in Brussels return with the answers you will receive by such route as may seem best to you; for this must depend upon the movements of the Spaniards. The chamberlain will furnish you with what money you may require." "Thanks, your excellency, I am provided with sufficient means for such a journey." "I need not tell you, my lad, to be careful and prudent. Remember, not only is your own life at stake, but that the interest of the country will suffer, and the lives of many will be forfeited should you fail in your mission. You will see that there are no names upon these letters; only a small private mark, differing in each case, by which you can distinguish them. Here is a paper which is a key to those marks. You must, before you start, learn by heart the names of those for whom the various letters are intended. In this way, should the letters fall into the hands of the Spaniards, they will have no clue as to the names of those to whom they are addressed. "This paper, on which is written 'To the Blue Cap in the South Corner of the Market Square of Brussels,' is intended to inclose all the other letters, and when you have learned the marks Count Nieuwenar will fasten them up in it and seal it with my seal. The object of doing this is, that should you be captured, you can state that your instructions from me are to deliver the packet to a man with a blue cap, who will meet you at the south corner of the Market Square at Brussels, and, touching you on the shoulder, ask 'How blows the wind in Holland?' These are the instructions I now give you. If such a man comes to you you will deliver the packet to him, if not you will open it and deliver the letters. But this last does not form part of your instructions.
