  “Yes, sir.  No mistake about that.  Oh! she's just as full of jasm!”

  Frank Sargent laughed again.  “You've got the start of me,” said he.  “Now tell me what ‘jasm’ is.”

  “Well, it’s a sort of word, I guess, that made itself,” said Cheek.  “It’s a good one though—jasm is. If you’ll take thunder and lightning, and a steamboat and a buzz-saw, and mix ’em up, and put ’em into a woman, that’s jasm.”

  I don’t think there is anything more pitiful than a man, who has been in business for himself, to have to give up and say he is a failure. It hurts to be compelled to go into some one’s shop as a clerk or a mechanic when you’ve once been your own master. It’ll put jasm into a lot of men that have lost their nerve and only need some one to set them straight.
