216 MR. W. B. HEMSLEY ON THE FLORA 
from the base of the fruit and the continuation into the fruit 
decays and falls away, leaving a circular aperture, about a third 
of an inch in diameter, and as clearly defined as though it had 
been cut. To form the humming-top, the natives bore holes at 
right angles to this and insert a peg, the exserted part being 
about as long as the diameter of the fruit. It is spun by a 
double string wound round the peg in the same direction, the 
free ends of the string being pulled in opposite directions to 
impart the impetus to the top. It is probable that this natural 
hole in the fruit serves as a point of egress for the radicle in 
germination.
