listening to the sky...

a detail from a 1940's "linen" postcard (so called because of the texture of the paper), of some military men with an incredible listening device to hear approaching airplanes. i suppose it is the equivalent of a telescope for ears. it would be nice if one could use such a device to listen to the stars or the sky, not for planes and bombs, but for voices that have somehow gotten lost, dawn or dusk stars perhaps, or the quiet breath and motion of clouds... i wonder how birdsongs from a nearby tree would sound coming through such a contraption, as well as someone in a treehouse whistling... does the moon make sounds as it drifts in orbit... and what about singing or playing records beneath this thing and projecting the sounds up to sky. i think the sky would like that.
