It is done by a particular effort of contraction. Only endeavour to be small, and you will find yourself becoming less.

RECAB.

I will try, then.

BELPHEGOR.

Where are you going? You have shot up to the height of a hundred feet through the roof of the house. You gave yourself a twist just contrary to what was required. I do not think, indeed, that this woman will contain you, now that you are let out to that size. But how long do you mean to stand projecting through the roof?

RECAB.

I wish you would bring me down again, for I do not like my situation at all.

BELPHEGOR.

Make another effort. Well done; you have descended to your ordinary stature at once. Try again: that is right—you are a foot shorter. You have acquired the true art of contraction. Now you are dwindling very prosperously, and at last are as diminutive and ridiculous as myself. After a little practice, you will draw yourself in and shoot yourself out at pleasure. But we have not yet completed our reduction; contract yourself till I desire you to stop. There; you are now small enough.
