"Anything else?" I asked, for Holmes was turning the pipe about in his hand, and staring at it in his peculiar pensive way.

He held it up and tapped on it with his long, thin fore-finger, as a professor might who was lecturing on a bone.

"Pipes are occasionally of extraordinary interest," said he. "Nothing has more individuality, save perhaps watches and bootlaces. The indications here, however, are neither very marked nor very important. The owner is obviously a muscular man, left-handed, with an excellent set of teeth, careless in his habits, and with no need to practise economy."

My friend threw out the information in a very offhand way, but I saw that he cocked his eye at me to see if I had followed his reasoning.

"You think a man must be well-to-do if he smokes a seven-shilling pipe," said I.

"This is Grosvenor mixture at eightpence an ounce," Holmes answered, knocking a little out on his palm. "As he might get an excellent smoke for half the price, he has no need to practise economy."
