The whole poem is an attempt to deal with words visually, and to create art as a single experience, having spatial, not temporal extension: to force poetry toward a closer kinship with painting and the plastic arts, and away from its kinship with music.  It is a picture of an action rather than a description of it; word-clusters representing each psrt of the action (take-off, leap, landing) are to be received simultaneously, not as words occurring one at a time.  In the penultimate line, for example, the arranging and the becoming are simultaneous processes.   One word is therefore as nearly superimposed upon the other as is physically possible.
