into nine parts, which they must always number according to the following plan: placing their backs against the centre of any of the walls they chuse to select, the most remote part of the floor to their left hand, they must call number one; and proceeding from their left hand to their right, in the order of their division; they will then have numbers one, two, and three in the first stripe; in the second; they will have four, five, and six; and in the third stripe, seven, eight, and nine, as this exhibits:
| 1 | 2 | 3 |
| 4 | 5 | 6 |
| 7 | 8 | 9 |
The familiar example of writing a letter, will fix the scale of division, by always proceeding in like manner, from the left hand to the right. When the floor is arranged, they must make a similar disposition of the walls, first establishing the order or numbers of them, beginning with the one which is to their left hand, and proceeding from left to right with them; they will thus have the second wall before them, the third at their right hand, and the fourth behind them. Then removing from their first position, and placing themselves in the centre of the floor, directly facing the first wall, they must divide it exactly on the plan of their floor, into nine parts, from left to right; the second, third, and fourth walls are to be arranged in the same manner, observing that they place themselves opposite each wall that they divide:—this last direction the author should not have considered necessary, were it not, that a gentleman in applying the system, conceiving that he ought not to stir from his first position, very ruefully told him, that he should be obliged to abandon the art, as he could
