This is a story of two families of children, with a couple of sailing boats, on a lake. There is a camp on an island, disputed by the two parties, the four who occupy the island, sailing thither in the Swallow, and two girls, who had previously camped there and sail the centreboard dinghy, Amazon. The idea is a sort of nursery Riddle of the Sands. This is a book which can be recommended with every confidence as a spontaneous and thoroughly successful effort to write a book about children for children and for their parents, guardians, cousins and aunts.
