to construct the hiding-place about which I spoke to you.  Here are some which are fifteen feet high.  They touch the ceiling of the room.  Around them I have arranged a perfect hedge or breast-work of smaller plants of the same family, growing in large boxes.  Nothing could penetrate through this prickly wall; and I have united the boxes by hooks and staples on the inside.  There is, however, one which a strong man can move aside; and through the opening thus formed he can crawl to the center of the barricade, and, having replaced the hooks, it would be almost impossible to reach him; while he could not be seen unless one were immediately over him and looked down upon him.  Then between him and the council room I have arranged a screen of flowers, which will hide you when you stand up, while between the blossoms you can see everything with little risk of being seen.  But in case you should be detected you will observe behind you a window, which, as the weather is warm, I shall leave open.  On the outside is a great ivy vine that will bear your weight.  You will have to dare the spines of the cacti behind you; make a great leap to the window and take your chances of escaping the fusillade of pistol shots, by flying in the darkness, into the garden.  I will show you the grounds so that you will not be lost in them, if you get that far.  If caught, you will have to pretend to be a burglar who entered at the window for purposes of plunder.  It would do you no good to inculpate me, for it would doom us both to instant death as spies; while a supposed burglar would be simply turned over to the law and punished by a term of imprisonment.  I give you these instructions although I hope there will be no necessity for them.  This hiding-place has been several times used, and the deepest secrets of the aristocracy revealed to our Brotherhood, without detection; and if you are prudent and careful there will be little to fear.  The council will meet at eight o’clock; at half past seven it will be my duty to see that the rooms are in order, and to make sure that there are no spies or intruders on the premises, and to so report in person to the Prince, and deliver him the key of the outer door.  I shall cover your dress with the garments of one of the household servants, and take you with me to help make that last examination; and, watching an opportunity, you will slip into the hiding-place; having first taken off the disguise I have lent you, which we will hide among the plants.  You must be armed and prepared for every emergency.  I will meet you in the garden at half past six; before we part I will furnish you with a key to an outer gate, by which you can enter.  As soon as the council has broken up, I will return to the room and again disguise you in the servant’s dress.  The Prince always entertains his guests with a lunch and champagne before they separate.
