But place the A against the M as it appears in the figure, and you may teach them to say A, M, AM; and thus all the way down the left side of the row of consonants.

If then you carry the vowel down on the other side of them, you will change the lesson, and by such means go on almost _ad infinitum_.

Double rows of consonants may be placed with a vowel between them, and when well practiced in this, they will ask for the vowel to be omitted that they may supply it, which they will do very readily and with great pleasure, while there is a tasking of the mind which cannot but prove beneficial.
Again, turn the frame with the balls round, so that the wires are perpendicular instead of horizontal, raise a ball gently, and say, To ascend, ascending, ascended; let it fall gently, saying, to descend, descending, descended; with a little explanation these words will then be understood, and others may be taught in the same way.

To fall, falling, fallen; to rise, rising, risen; to go, going, gone, will readily occur, and others will easily be supplied by the ingenuity of the instructor.

The frame may also be applied to _grammar_.
It is to be used as follows:--Move one of the balls to a part of the frame distinct from the rest.
