was always having the
doctor for you, and you got cold the easiest of any person I ever
saw--and do to this day----"

"That is perfectly ridiculous, Lemuel."

"I believe you're sitting in a draught now, Dora," said Mr. Lockwood,
quickly.

"Well--I----Achoo! I believe you! I never did see such a draughty place
as this house, Lemuel. Ahem! Dora! get me my little knit shawl, will
you, child?"

"Oh, yes, Auntie," said one of the twins, as they both rose.

"We're both through our suppers, Auntie," said the other. "We'll bring
the shawl."

"Now!" exclaimed the exasperated old lady, when the twins were out of
the room. "Which of 'em went for it?"

Her brother shook his head sadly, but his eyes were a-twinkle. "I could
not undertake to say, Sister."

It annoyed Aunt Dora very much to hear the girls talk continually of the
coming Big Day on Lake Luna and the part the girls of Central High would
take in the races. And that next week Dora and Dorothy certainly were
full of the new eight-oared shell.

It arrived at the boathouse early in the week, and proved to be the
handsomest shell that had ever been launched in Luna waters. Even the
wealthy Luna Boat Club did not own a shell like it.

Every other afternoon Mrs. Case allowed the crew to go out for a spin,
and Professor Dimp, who coached the boys' crews, looked after the girls'
rowing, as well. Some of the girls' parents went down to the shore in
the early evening to watch the practice work off Colonel Richard
Swayne's estate; but would Aunt Dora go? Only once!

By some inquiry she learned that each member of the crew of eight girls
had her own particular seat in the big shell. Dorothy was supposed to
row Number 2 and Dora Number 6. But the twins sometimes changed
seats--and who was to know the difference?

Not the coach, for Professor Dimp could tell them apart no better than
other people. Had Aunt Dora been sure that her namesake rowed in her
right place on the evening when she viewed the practice, she would have
met the shell at the landing, seized Number 6 oar, and marched her home
and locked her into her own room until tickets could be bought for Aunt
Dora's home city.

But in their natty-looking costumes the twins looked more alike than
ever--were that possible!

TOMMY LONG HAS A BAD DAY

It was all in the papers one evening about detectives from Centerport's
police headquarters, aided by the park police, beating the eastern end
