upted hour together. For Kai Bok-su
was always in demand to visit the sick or sad or troubled.

There was a little kitchen separate from the house on the bluff, and
over this Mackay with his students built a second story. And here they
would often slip away for a little quiet time together. One night, about
eleven o'clock, Mackay was here alone poring over his books. The young
men had gone home to bed except two or three who were in the kitchen
below. Some papers had been dropped over a pipe-hole in the floor of the
room where Mackay was studying, and for some time he had been disturbed
by a rustling among them. At last without looking up, he called to his
boys below: "I think there are rats up here among my papers!"

Koa Kau, one of the younger of the students, ran lightly up the stairs
to give battle to the intruders. What was his horror when he saw fully
three feet of a monster serpent sticking up through the pipe-hole and
waving its horrible head in the air just a little distance from Kai
Bok-su's chair.

The boy gave a shout, darted down the stair, and with a sharp stick,
pinned the body of the snake to the wall below. The creature became
terribly violent, but Koa Kau held on valiantly and Mackay seized an
old Chinese spear that happened to be in the room above and pierced
the serpent through the head. They pulled its dead body down into the
kitchen below and spread it out. It measured nine feet. The students
would not rest until it was buried, and the remembrance of the horrible
creature's visit for some time spoiled the charm of the little upper
room.

The rocks at Kelung harbor were another favorite spot for this little
traveling university to hold its classes. Sometimes they would take
their dinner and row out in a little sampan to the rocks outside the
harbor and there, undisturbed, they would study the whole day long.

They always began the day's work with a prayer and a hymn of praise, and
no matter what subjects they might study, most of the time was spent on
the greatest of books. After a hard morning's work each one would gather
sticks, make a fire, and they would have their dinner of vegetables,
rice, and pork or buffalo-meat. Then there were oysters, taken fresh off
the rocks, to add to their bill of fare.

At five in the afternoon, when the strain of study was beginning to
tell, they would vary the program. One or two of the boys would take
a plunge into the sea and bring up a subject for study,-
