I think everyone expected to see a man emerge--possibly something a
little unlike us terrestrial men, but in all essentials a man.  I know
I did.  But, looking, I presently saw something stirring within the
shadow: greyish billowy movements, one above another, and then two
luminous disks--like eyes.  Then something resembling a little grey
snake, about the thickness of a walking stick, coiled up out of the
writhing middle, and wriggled in the air towards me--and then another.
