Did the host encourage his guest to chant in a modulated voice a strange legend on an allied theme?

Reassuringly, their place, where none could hear them talk, being secluded, reassured, the decocted beverages, allowing for subsolid residual sediment of a mechanical mixture, water plus sugar plus cream plus cocoa, having been consumed.

Recite the first (major) part of this chanted legend.

    Little Harry Hughes and his SCHOOLFELLOWS all
    went out for to play ball. 
    And the very first ball little Harry Hughes played
    he drove it o’er the jew’s garden wall. 
    And the very second ball little Harry Hughes played
    he broke the jew’s windows all.

How did the son of Rudolph receive this first part?

With unmixed feeling.  Smiling, a jew he heard with pleasure and saw the unbroken kitchen window.

Recite the second part (minor) of the legend.

    Then out there came the jew’s daughter
    and she all dressed in green. 
    “Come back, come back, you pretty little boy,
    and play your ball again.”

    “I can’t come back and I won’t come back
    without my SCHOOLFELLOWS all. 
    For if my master he did hear
    he’d make it A sorry ball.”

    She took him by the LILYWHITE hand
    and led him along the hall
    until she led him to A room
    where none could hear him call.

    She took A penknife out of her pocket
    and cut off his little head. 
    And now he’ll play his ball no more
    for he lies among the dead.

How did the father of Millicent receive this second part?

With mixed feelings.  Unsmiling, he heard and saw with wonder a jew’s daughter, all dressed in green.

Condense Stephen’s commentary.

One of all, the least of all, is the victim predestined.  Once by inadvertence twice by design he challenges his destiny.  It comes when he is abandoned and challenges him reluctant and, as an apparition of hope and youth, holds him unresisting.  It leads him to a strange habitation, to a secret infidel apartment, and there, implacable, immolates him, consenting.
