Alfred Hitchcock horror anthology for children in the 1960s

Question

Back in the 1960s I read an Alfred Hitchcock anthology of horror or suspense stories for children. I guess that Hitchcock merely lent his name to the anthology.

If I remember correctly, the book had a mostly greenish hard cover.

I remember bits of three stories:

In one story, a vampire was discovered and defeated. The vampire unusually could turn into an owl instead of a bat.

In one story there was reference to how unhealthy West Africa was for European explorers and colonists due to tropical diseases, and someone recited a poem about the Bight of Benin. The version of the rhyme in this story went:

The Bight of Benin, the Bight of Benin.
One comes out where three goes in.

And I remember that another story had a reference to, or a visit to, New Hope, Bucks County, Pennsylvania, which I have never lived very far from.

So I ask if anyone remembers that book or any story from it.

Answer 1

This is likely Haunted Houseful (1961).

It contains "The Forgotten Island" by Elizabeth Coatsworth, which contains a reference to the Bight of Benin couplet:

"Yes, and tell what was written over the mantel in queer letters—you remember we learned it—'Oh, the Bight of' what was it, John?

"Oh, the Bight of Benin,
The Bight of Benin,
One comes out
Where three goes in."

"The Mystery of Rabbit Run" by Jack Bechdolt is set in New Hope, Pennsylvania, which lies in Bucks County:

Three young travelers in single file plodded through midsummer heat, crossing the bridge between Lambertville, which is in New Jersey, and the village of New Hope, in Pennsylvania.

There are a couple of explicit references to "Bucks County" in the story:

"Well," said Captain Ben, "he's a rich man from out in Indiana or some place, that's bought the old Fairfields place and is tryin' to mind the business of everybody in Bucks County. But don't you let him worry you. If he did make a trespassin' charge against you, the court would throw it out."
