a large sawmill, and a yard, near the lake, in which yard were piled
many stacks of lumber.

Nan and Bert were the older Bobbsey twins, being past nine, while
Flossie and Freddie were about "half-past-five." So you see that is
how there were two sets of twins. Nan was a tall, slender girl, with a
dark face and red cheeks. Her eyes were brown, and so were her curls.
Bert, too, was quite dark, like Nan.

Flossie and Freddie were very light, with blue eyes. They were short
and fat, instead of tall and thin. So you see the two sets of twins
were very different.

Oh! such good times as the Bobbsey twins had! I could not tell you all
of them, if I wrote a dozen books. But some of the good times I have
related in the first book. In the second, called "The Bobbsey Twins in
the Country," there are more happenings mentioned.

Uncle Daniel Bobbsey, his wife Sarah, and their son Harry lived in the
country, at a place called Meadow Brook, and there the twins often
went on their vacation.

Uncle William Minturn, and his wife Emily, with their nine-year-old
daughter Dorothy, lived at Ocean Cliff. As you might guess, this was
on the coast, and in the third book, "The Bobbsey Twins at the
Seashore," I have told you of the good times the children had there,
how they saw a wreck, and what came of it.

In "The Bobbsey Twins at School" you will find out how they came to
get the dog Snap, as a pet. They already had a black cat, named Snoop,
