The boomerang did all that Riley had said of it and more: at one point, having returned, it rose and floated above the Aboriginal's head in a slow circle before descending into his hand. Stephen and Martin gazed at the object in astonishment, turning it over and over in their hands. 'I cannot understand the principle at all,' said Stephen. 'I should very much like to show it to Captain Aubrey, who is so very well versed in the mathematics and dynamics of sailing. Landlord, pray ask him whether he is willing to part with the instrument.' 'Not on your fucking life,' said the Aboriginal, snatching the boomerang and clasping it to his bosom. 'He says he does not choose to dispose of it, your honour,' said the landlord.
