"Innocently to amuse the imagination in this dream of life is wisdom." So wrote Oliver Goldsmith; and surely among those who have earned the world's gratitude by this ministration he must be accorded a conspicuous place. If, in these delightful writings of his, he mostly avoids the darker problems of existence-if the mystery of the tragic and apparently unmerited and unrequited suffering in the world is rarely touched upon-we can pardon the omission for the sake of the gentle optimism that would rather look on the kindly side of life. "You come hot and tired from the day's battle, and this sweet minstrel sings to you," says Mr. Thackeray.
