The student will observe that No. 2 is marked as the fire-place, and no matter what position or part of the room the fire-place occupies, it is always No. 2. No. 1 is always on the left hand side of the fire-place, and 3 on the right hand side, and No. 5 is always the centre of the room. The reader must commit the positions to memory so that whenever he wishes to think of any part of his room, he will instantly be able to state what the number of that part is, for example—if he were to be asked which is "5" he should at once say the "centre," or, which is "2" the "fire-place," and so on throughout the whole of the positions.
If any doubt should arise as to which way the positions are to be counted, place the preceeding diagram of the room on your table, with the numbers 1, 2, & 3, towards the fire-place, and you will at once have them as they are to be used. Anything that may be in either of the divisions of your room, is called by the number of the position that it is in, and you are at liberty to connect as many associations to it as you think fit. If you choose, you are for the purpose of association, at liberty to imagine anything you like in either portion of your room.
