no pun intended.

The horse having reached the end of his tether, so to speak, halted and,
rearing high a proud feathering tail, added his quota by letting fall on
the floor which the brush would soon brush up and polish, three smoking
globes of turds. Slowly three times, one after another, from a full
crupper he mired. And humanely his driver waited till he (or she) had
ended, patient in his scythed car.

Side by side Bloom, profiting by the _contretemps_, with Stephen passed
through the gap of the chains, divided by the upright, and, stepping
over a strand of mire, went across towards Gardiner street lower,
Stephen singing more boldly, but not loudly, the end of the ballad.

_Und alle Schiffe bruecken._

The driver never said a word, good, bad or indifferent, but merely
watched the two figures, as he sat on his lowbacked car, both black,
one full, one lean, walk towards the railway bridge, _to be married by
Father Maher_. As they walked they at times stopped and walked again
continuing their _tete-a-tete_ (which, of course, he was utterly out
of) about sirens enemies of man's reason, mingled with a number of other
topics of the same category, usurpers, historical cases of the kind

sleeper car who in any case couldn't possibly hear because they were too
far simply sat in his seat near the end of lower Gardiner street _and
looked after their lowbacked car_.

What parallel courses did Bloom and Stephen follow returning?

Starting united both at normal walking pace from Beresford place they
followed in the order named Lower and Middle Gardiner streets and
Mountjoy square, west: then, at reduced pace, each bearing left,
Gardiner's place by an inadvertence as far as the farther corner of
Temple street: then, at reduced pace with interruptions of halt, bearing
right, Temple street, north, as far as Hardwicke place. Approaching,
disparate, at relaxed walking pace they crossed both the circus before
George's church diametrically, the chord in any circle being less than
the arc which it subtends.

Of what did the duumvirate deliberate during their itinerary?

Music, literature, Ireland, Dublin, Paris, friendship, woman,
prostitution, diet, the influence of gaslight or the light of arc and
glowlamps on the growth of adjoining paraheliotropic trees, exposed
corporation emergency dustbuckets, the Roman catholic church,
ecclesiastical celibacy, the
