have completed the circle of the card, naming each point and
sub-division as we go along. Then you should learn to read it backward
as well. After you have learned to do that I will show you how to lay
a course by a chart."

"I don't thee anything to read," said Tommy, squinting down at the
card.

"You are not taking the lesson, darlin'," Jane reminded her.

"This is the way to begin," Captain Billy told them. "First is North.
Then you say north one-quarter, one-half, three-quarters, then the
next sub-division is North by East with the same fractions of degrees.
We go on as you will see by following the card, as follows, North
Northeast; Northeast by North; Northeast; Northeast by East; East
Northeast; East by North; East. You proceed in exactly the same manner
with the other cardinal points, East, South and West, and that is what
is called 'boxing the compass.' Do you think you understand, Miss
Burrell?"

"I have at least a start," replied Harriet smilingly.

"I haven't," declared Tommy with emphasis. "I couldn't thpeak at all
if I repeated that awful thtuff."

In the meantime Harriet was gazing steadily at the card, fixing the
points in mind, really photographing the points of the compass and
their sub-divisions on her memory, the skipper observing her with a
dry smile. He thought he had given the young sailor a problem that
would keep her busy for some days to come. What was his surprise,
therefore, when just after they had come to anchor, Harriet asked him
to hear her lesson. She began boxing the compass and only once did she
pause until she had gone all the way around the card.

"How near right was I, Captain?" she asked.

"Right as a plumb line. Girl, you're a wonder. Took me four months to
learn to read the card; then I didn't have it down as fine as you
have. Will you forget it before to-morrow morning?"

"Oh, dear me, no," she laughed. "I hope I shall not," added the girl,
sobering a little. "I shall write the points down as soon as possible
after I get back to camp."

"If you have it down fine in the morning, I'll take you for a long
sail to-morrow," promised the captain, as he assisted the girls over
the side into the waiting small boat.

The Wau-Wau girls voted it the most delightful day they ever had
spent. When they had reached camp, however, Harriet heard something
that caused her to think even more seriously of what already had
happened at Camp Wau-Wau. Before the night was over she was to
