soon joined the throngs that filled the vast temple of St. Peter's,
to which all turn during this solemn season. After attending a service
and viewing the treasures of the Cathedral, they turned their steps to
the Sistine Chapel, which contains the wonderful painting of the Last
Judgment by Michael Angelo. It was here that the celebrated Miserere
by Allegri was performed. Wolfgang had been looking forward to this
moment all through the latter part of his journey. His father had told

tall candles on the altar are extinguished one by one,--till but one
is left, which is removed to a space behind the altar. Then in almost

the antiphon, or short introduction,--and then comes silence, a
silence so profound that the listener scarcely dares to breathe
for fear of disturbing it. At length the first sad notes of the
supplication are heard, like the softest wailing of an anguished
spirit; they gradually gain force till the whole building seems to
throb with the thrilling intensity of the music.

He arose, lit the lamp, and got out pens and music paper. He worked
industriously the long night through. When morning dawned the boy sat
with his beautiful head upon his folded arms, asleep, while before him
