about this.  I do not know what it is, but the fear makes me sick, and I
cannot eat, though the servants bring me the best of food; and they pet
me so, and even come in the night, and cry, and say, "Poor doggie--do
give it up and come home; don't break our hearts!" and all this terrifies
me the more, and makes me sure something has happened.  And I am so weak;
since yesterday I cannot stand on my feet anymore.  And within this hour
the servants, looking toward the sun where it was sinking out of sight
and the night chill coming on, said things I could not understand, but
they carried something cold to my heart. 

"Those poor creatures! They do not suspect.  They will come home in the
morning, and eagerly ask for the little doggie that did the brave deed,
and who of us will be strong enough to say the truth to them: 'The
humble little friend is gone where go the beasts that perish.'"
