High boys."

"And one that's always been just as full of mischief as an egg is full
of meat," snapped Dora.

Now, supposing there had been a blind person in the canoe with the
Lockwood sisters, that unfortunate person could never in this world have
told which girl spoke at each time. Their voices were exactly alike--the
same inflection, the same turning of phrases, the exact tone.

Nor could this supposititious blind person--had his eyes been suddenly
opened--have been able to tell the girls apart, either!

For Dora and Dorothy Lockwood were exactly the same height, of the same
physical development, and with the same mannerisms and carriage. Both
had a wealth of rather light brown hair, and that hair was tied with
ribbons of exactly the same shade, and tied in exactly the same kind of
bow. They possessed two pairs of very nice gray eyes, usually sparkling
with fun. Each had a dimple at the left side of her pretty lips, and
when they smiled that dimple came into prominence at once. The turn of
their chins, the shape of their noses and ears, the breadth of their
foreheads--every feature was the same. One's reflection in the
looking-glass could be no more exactly like the original than was her
sister.

So, unless some person was near enough to watch the play of the twins'
lips, it would have been impossible to tell which girl spoke.

They had been paddling for some time--from the boat landing at the
Girls' Branch Athletic Field of Central High, at Centerport, to the East
Point of Cavern Island, and beyond.

Lake Luna was a beautiful body of water some twenty miles in length and
a half-mile broad. Cavern Island lay in its middle directly opposite the
city of Centerport. At the upper, or west end of the lake, lay
Lumberport, another lively town, at the mouth of Rocky River; and at the
far eastern end of the lake its waters flowed out through Rolling River
at the city of Keyport.

Back of the city of Centerport, which was by far the largest and most
important of the three, was a range of beautiful hills--hills which were
now clothed in their mantle of full summer verdure. There was, about in
the middle of the big town, a slight elevation occupied by the best
residences. This "hill section" of Centerport was flanked on either hand
by business portions of the city; but on the lake shore side of the Hill
there were beautiful estates, boat clubs, bathing pavilions, and the new
Athletic Field established for the use o
