"Which surely he restored to their owner?"

"My dear fellow, there lies the problem. It is true that 'For Mrs. Henry Baker' was printed upon a small card which was tied to the bird's left leg, and it is also true that the initials 'H. B.' are legible upon the lining of this hat, but as there are some thousands of Bakers, and some hundreds of Henry Bakers in this city of ours, it is not easy to restore lost property to any one of them."

"What, then, did Peterson do?"

"He brought round both hat and goose to me on Christmas morning, knowing that even the smallest problems are of interest to me. The goose we retained until this morning, when there were signs that, in spite of the slight frost, it would be well that it should be eaten without unnecessary delay. Its finder has carried it off, therefore, to fulfil the ultimate destiny of a goose, while I continue to retain the hat of the unknown gentleman who lost his Christmas dinner."

"Did he not advertise?"

"No."

"Then, what clue could you have as to his identity?"

"Only as much as we can deduce."

"From his hat?"

"Precisely."

"But you are joking. What can you gather from this old battered felt?"

"Here is my lens. You know my methods. What can you gather yourself as to the individuality of the man who has worn this article?"

I took the tattered object in my hands and turned it over rather ruefully. It was a very ordinary black hat of the usual round shape, hard and much the worse for wear. The lining had been of red silk, but was a good deal discoloured. There was no maker's name; but, as Holmes had remarked, the initials "H. B." were scrawled upon one side. It was pierced in the brim for a hat-securer, but the elastic was missing. For the rest, it was cracked, exceedingly dusty, and spotted in several places, although there seemed to have been some attempt to hide the discoloured patches by smearing them with ink.

"I can see nothing," said I, handing it back to my friend.

"On the contrary, Watson, you can see everything. You fail, however, to reason from what you see. You are too timid in drawing your inferences."
