about eight o'clock
William Hill , aged twelve , was playing in Glendale last night with some companions . They were playing ` hide and go seek ' and William hid . He could not be found by the boy who was searching and has not been found since . His companions became frightened and reported it about eight o'clock . They saw nothing , but mark this ! Four of them agree that they heard a sound in the air _ like a motor humming _ . '' `` That proves nothing . ''
