Their carriage began to move

All waited. Nothing was said. Stowing in the wreaths probably. I am sitting on something hard. Ah, that soap in my hip pocket. Better shift it out of that. Wait for an opportunity.
All waited. Then wheels were heard from in front turning: then nearer: then horses' hoofs. A jolt. Their carriage began to move, creaking and swaying. Other hoofs and creaking wheels started behind. The blinds of the avenue passed and number nine with its craped knocker, door ajar. At walking pace.
They waited still, their knees jogging, till they had turned and were passing along the tramtracks. Tritonville road. Quicker. The wheels rattled rolling over the cobbled causeway and the crazy glasses shook rattling in the doorframes.
-- What way is he taking us? Mr Power asked through both windows.
-- Irishtown, Martin Cunningham said. Ringsend. Brunswick street.
Mr Dedalus nodded, looking out.
-- That's a fine old custom, he said. I am glad to see it has not died out.
All watched awhile through their windows caps and hats lifted by passers. Respect. The carriage swerved from the tramtrack to the smoother road past Watery lane. Mr Bloom at gaze saw a lithe young man, clad in mourning, a wide hat.
-- There's a friend of yours gone by, Dedalus, he said.
-- Who is that?
-- Your son and heir.
-- Where is he? Mr Dedalus said, stretching over across.
The carriage, passing the open drains and mounds of rippedup roadway before the tenement houses, lurched round the corner and, swerving back to the tramtrack, rolled on noisily with chattering wheels. Mr Dedalus fell back, saying:
-- Was that Mulligan cad with him? His fidus Achates?
