great poet, Sir Walter Scott, has remarked in one of his charming poems.

If all these investigations of mine were conducted without the knowledge of Walsingham Gribbs, you must admit I did only what was right in keeping them secret from him; for since he had never met my daughter he might have considered the efforts of a perfect stranger to peer into his life as being uncalled for. My wife did what she could to comfort Anne, but Anne sadly replied that she could never marry a man that staggered and reeled day in and day out. Thus day by day she became more sad, and I became so upset that I actually sold a narrow-brimmed derby hat to a man with wide, outstanding ears.

Of course this could not go on. No high-grade hat business could support it, and I was standing in my shop door looking gloomily out when I chanced to see Walsingham Gribbs stagger by. I had seen him many times, but now, for the first time I noticed what I should have noticed before—that he invariably wore a high hat, or “topper,” as our customers like to call them.

I observed that the shape was awful, and that the hat badly needed the iron, and then my mind recurred to the old problem of the vacant space in the top of top hats; but I found I could not concentrate. Whenever I tried to think of top hats I thought of Walsingham8 Gribbs in one of them, staggering and reeling up the street, and gradually the thought came that it would be an excellent idea should I be able so to use the space in the top of Walsingham’s hat that he would no longer stagger and reel, and then the thought of the gyroscope hat came to me.

I admit that at first I put the idea aside as futile, but it came back again and again, and at length it seemed to force me into enthusiasm. I dropped everything and went to work on the gyro-hat.

The gyroscope is, as everyone knows, a top, and I might have called the hat I invented a top hat, except that any tall cylindrical silk or beaver hat is called a top hat, so I was forced to adopt the name of gyro-hat.

A gyroscope is not an ordinary top. It is like a heavy fly wheel, revolving on an axis; and if it is spun, the speed of the revolutions maintains the axis in the perpendicular. A huge gyroscope is used to steady the channel steamers, which would otherwise stagger and reel. A gyroscope has just been adopted to the monorail cars, and so long as the gyroscope gyrates the monorail car cannot stagger or reel. If a proper gyroscope was
