Another Childhood Memory
I've been trying to remember the titles of a series of books which I read in the 1960's.
It was about a group of children (weren't they all in those days), who lived on an island (don't think it was all year round), and had a number of adventures. I think the island was in the middle of the River Thames, near London, but they had the right to produce there own postage stamps. One of the children ( I think the youngest) was nicknamed 'Gunner's Mate' and could make explosives using a mixture of saltpetre and sugar, which came in handy for some of their adventures. They also had a motor launch which I think may have been called 'The Cormorant'.
I can't remember any more about the books.
