I suppose there was some spring which held them.

Then we screamed; but I could feel that the inside was all thickly padded.

I suppose our voices could not be heard outside.

I thought so, because once I thought I heard the gondoliers singing, but it was so faint that I could not be sure.

Then the air seemed stiflingly close, and I fainted; and when I came to myself one of the windows was open, and Giulia said she had promised we would not scream, but I think we were beyond the canals then, for I could see nothing but the sky as we passed along.
