Dickens gave his first formal expression to his Christmas thoughts in his series of small books, the first of which was the famous "Christmas Carol," the one perfect chrysolite. The success of the book was immediate. Thackeray wrote of it: "Who can listen to objections regarding such a book as this? It seems to me a national benefit, and to every man or woman who reads it, a personal kindness."This volume was put forth in a very attractive manner, with illustrations by John Leech, who was the first artist to make these characters live, and his drawings were varied and spirited.There followed upon this four others: "The Chimes," "The Cricket on the Hearth," "The Battle of Life," and "The Haunted Man," with illustrations on their first appearance by Doyle, Maclise, and others. The five are known to-day as the "Christmas Books." Of them all the "Carol" is the best known and loved, and "The Cricket on the Hearth," although third in the series, is perhaps next in point of popularity, and is especially familiar to Americans through Joseph Jefferson's characterisation of Caleb Plummer.
