I suppose it is natural late in one's life to look back and enjoy again some of the more precious moments of earlier life. A number of my friends have urged me to record a collection of these earlier moments. It didn't take much reflection to realize that, if I were to keep the treatment within reasonable bounds, I must limit myself by some rule of selection. I decided to concentrate chiefly on those moments more or less connected either with mathematics or with teaching, two pursuits that have occupied such a large part of my life.

And so, with deep apologies for the naiveté of my presentations, and with the kind forbearance of my understanding readers, I here offer the following potpourri of fifty nostalgic tales, thoughts, and escapades. They are presented in no particular logical order, but rather as they occurred to me. Some of the tales required only a few lines while others needed a few pages.
