The clear tones had leaped a full octave, and with a mingled sound of
pipes and flutes went trilling deliriously on a high note until the

stopped, ending in a queer, unfinished way that tantalized their ears
for many minutes afterward, and held them motionless, spellbound,
waiting for the strain to be resumed. They listened in vain; the
mysterious piper called no more. Soon afterward a bugle pealed forth,
sounding the mess call, and coming to earth with a start, the two girls
raced back to Ponemah with their water pitcher and then hastened on
into the dining room, where the campers, now all clad in regulation blue
bloomers and white middies, were already assembled.

picturesque building among the trees was painted in large ornamental
letters:
