So we built a klepalo, getting from Lumberville a stick of seasoned oak,
1-1/2 inches thick, 6 inches wide and 4 feet long. A hole was drilled into
the stick at the center, and by a rope passed through this hole the beam
was suspended from a branch overhanging the camp. Jack, the cook,
regularly used this crude device to call the hungry horde to meals.

CHAPTER VII.
SURVEYING.
One of the first things we did after getting fairly settled in our new
quarters was to make a complete survey of Willow Clump Island and its
immediate surroundings. Our surveying instruments were made as follows:
The Surveying Instrument.
[Illustration: Fig. 71. Baseboard of the Surveying Instrument.]
[Illustration: Fig. 72. Sighting Blocks on the Baseboard.]
Out of a 1-inch board we cut a base 15 inches long and 4 inches wide. In
the center we sawed out a circular opening of about 3 inches diameter and
covered this at the bottom by a circular piece 1 inch thick and 5 inches
in diameter, thus forming a socket in which our compass fitted snugly. A
hole 1 inch in diameter was drilled through the center of this circular
piece to receive the pivot pin of a tripod. Across each end of the
baseboard we secured a block 4 inches long, 2 inches wide and 1 inch
thick.
