[_Disappears from window. A moment later comes running out, one braid of hair up and one braid down. Again looks wildly up in the air._] Where is it? IAN [_Absorbed in the sun-dial._] Where’s what? ELOISE The airplane. IAN Airplane? It’s the sun-dial. It’s right. Just look at this six o’clock shadow. [_She goes around to the other side of it._] It’s absolutely, mathematically--you’re in the way of the sun, Eloise. [_She steps aside._] Look! the style is set square on the true north--this is the fifteenth of June--the clock is checked to the second by telegraph with the observatory at Washington and see! the clock is exactly nineteen minutes and twenty seconds behind the shadow--the precise difference between Provincetown local time and standard Eastern time. ELOISE Then the sun-dial’s really finished--and working right! After all these, weeks! Oh, Ian! [_Embraces him._ IAN It’s good to get it right after all those mistakes. [_With vision._] Why, Eloise, getting this right has been a symbol of man’s whole search for truth--the discovery and correction of error--the mind compelled to conform step by step to astronomical fact--to truth. ELOISE [_Going to it again._] And to think that it’s the sun-dial which is true and the clock--all the clocks--are wrong! I’m glad it is true. Alice Knight has been here talking to me for an hour. I want to think that something’s true. IAN That’s just it, Eloise. The sun-dial is more than sun-dial. It’s a first-hand relation with truth. A personal relation. When you take your time from a clock you are mechanically getting information from a machine. You’re nothing but a clock yourself. ELOISE Like Alice Knight. IAN But the sun-dial--this shadow is an original document--a scholar’s source. ELOISE To tell time by the shadow of the sun--so large and simple. IAN I wouldn’t call it simple. Here on this diagram I have worked out-- ELOISE Dearest, you know I can’t understand diagrams. But I get the feeling of it, Ian--the sun, the North star. I love to think that this [_Placing her hands on the style_] is set by the North star. [_Her right hand remains on the style, her left prolongs its line heavenward._] Why, if I could go on long enough I’d get _to_ the North star! IAN [_Impressively._] The line that passes along the edge of this style joins the two poles of the heavens. [_ELOISE pulls away her hand as one who fears an electric shock._] Look at this slow shadow and what you see is the spin of the earth on its axis. It is not so much the measure of time as time itself made visible. ELOISE [_Knitting her brows to get this: escaping to an impetuous generality._] Ian, which do you think is the more wonderful--space _or_ time? IAN [_Again sighting over his east and west lines. Good-humoredly._] Both are a little large for our approbation. ELOISE
