I picked up an old copy of this book in a local second-hand bookshop a few months back, and it is a delightful volume to dip into and read a tale from now and again. It recounts incidents from Kenneth Grahame's unusual childhood (he was one of five orphaned children brought up by a group of Aunts and Uncles usually referred to as "The Olympians". Dream Days is a sequel to his earlier book "The Golden Age". I have not yet read that, but it really doesn't matter, as each story in this volume can be read on its own - many of the eight stories in the book apparently first appeared in periodicals. The best known story in this book is "The Reluctant Dragon", which is also available separately these days.
I thoroughly enjoyed Dream Days. Kenneth Grahame uses erudite language wonderfully and it seems clear that he received an excellent classical education, as I was forced to reach for a dictionary on more than one occasion (and am now looking forward to the day I have an opportunity to drop one of these newly acquired words casually into a conversation). It is easy to imagine his original readers chortling over these tales in some gas-lit Gentleman's club. The contrast between the rolling and rhetorical language and the childish joys and troubles being described is somehow very satisfying. I especially enjoyed "A saga of the seas", in which Grahame recalls an afternoon of make-believe after he was banished to the "St Helena of the nursery" after remonstrating with a visitor who had knocked over some of his tin soldiers, and which taught me the words flagitious and carronade.
Anyone considering buying this for a child who has already enjoyed "The Wind in the Willows" should bear in mind that this is a book about children, but not really a book for children, though it might please a very well-read child who is already used to reading Victorian prose and who is at least 11 or 12 years old.
