Solvers are to determine the identity of the diagram's center by performing the following operation: sixteen clue answers (8 Acrosses and 8 Downs) should have one letter deleted before they are entered in the grid; in the order of their occurrence (Acrosses preceding Downs), these sixteen letters should be entered from top to bottom in the four columns of the center, starting at the left.
Numbers in parentheses refer to the lengths of the final diagram entries only. Answers include one proper noun; 13A is a form not found in Webster's. Punctuation in the clues may be used deceptively.
