quite by accident, in the course of play, we discovered
that when each, with one hand and foot, held on to the
other's log, the logs were steadied and did not turn
over. Lying side by side in this position, our outside
hands and feet were left free for paddling. Our final
discovery was that this arrangement enabled us to use

there our discoveries ended. We had invented the most
primitive catamaran, and we did not have sense enough
to know it. It never entered our heads to lash the
logs together with tough vines or stringy roots. We
were content to hold the logs together with our hands
and feet.

It was not until we got over our first enthusiasm for
navigation and had begun to return to our tree-shelter
to sleep at night, that we found the Swift One. I saw
her first, gathering young acorns from the branches of
a large oak near our tree. She was very timid. At
first, she kept very still; but when she saw that she

And then, one day, she did not run away. She waited

close, she darted suddenly away and from a safe
