are you "old" enough to recall Bert and Nan, who were 12 years old, and Flossie and Freddie, who were six? they were the two sets of fraternal twins born to Richard and Mary Bobbsey. today, many of the younger generation of readers are not even aware of them. 

the series was quite popular way back then and although a New Bobbsey Twins series came out in 1987 to 1992, the charm of the original books could never be matched.

I have been making my way through the Bobbsey Twins books as an adult; we had only one in the house when I was growing up (The Bobbsey Twins Or, Merry Days Indoors and Out), which I read over and over again.

Of course, these books seem dreadfully dated to me now, but nevertheless I enjoy reading about the antics of the four Bobbsey children.

In this outing, they are all at a Sunday school picnic when a merry-go-round arrives in an out-of-order state. They're fascinated by it, so their father says he will take them to the fair for which the device is bound (since it is near to their Uncle Daniel's farm).

Of course, the children get into all kinds of scrapes (it's mostly the younger twins) at the fair, and at the end of the day all is well.

These books are a great opportunity for parents to talk about how times have changed with their kids and address issues of racism, etc., that are taken for granted in the text.

The Bobbsey Twins: or, Merry Days Indoor...

I have always loved this series since I was very little.
