‘Ten bucks to start her off,’ he said shortly.

Longstreet had supposed it customary to begin with a dollar; in his mind, however, there was little difference between one and ten.  Therefore he made no remark and placed his own money in the pot.  The two Mexicans tossed their cards away.  Courtot, looking at no one, and without speaking, came in.  Longstreet dealt a second round.  Now Courtot had two fours in sight; Barbee had two aces; Longstreet a king and a seven exposed, but also a king hidden.  When Barbee said, ’Twenty bucks to play,’ and said it viciously with a jeering stare at Courtot, Longstreet began counting out his money.  But before he had completed the slow process the street door opened.

It was Alan Howard.  He stood a moment on the threshold, his look one of sheer amazement.  He had come looking for Professor James Edward Longstreet, eminent authority upon certain geological subjects.  Had anyone told him that he would find his man playing stud poker with Barbee and two Mexicans and Jim Courtot——­

‘Barbee!’ he cried out angrily, coming on swiftly until he stood over the table.  ’What in hell’s name do you mean by steering Longstreet into a mess like this?’

‘What do you mean?’ retorted Barbee hotly.  ’What business is it of yours?’

‘I mean Jim Courtot,’ cut in Howard shortly.  ’You know better than to drag any friend of mine into a game with him.’

Courtot appeared calm and unconcerned.

‘The bet’s made, gents,’ he said briefly.  ‘Coming in, Longstreet?’

Longstreet looked confused.  Before he could frame his answer, Howard made it for him.  And he directed it straight to Courtot.

’I haven’t had time to tell Mr. Longstreet about all of the undesirable citizens hereabouts,’ he announced steadily.  ‘No, he’s not coming in.’

‘I imagine you’ll spill an earful when you get going, Alan,’ said Courtot.  ‘I’d like to listen in on it.’

Straightway the two Mexicans rose and left the table.  Barbee, though he scorned to do so, pushed his chair back a little and kept his eyes upon the faces of the two men.  Longstreet went from confusion to bewilderment.  Howard considered the matter briefly; then, watching Jim Courtot while he spoke, he said crisply: 

’Mr. Longstreet, you should get acquainted a bit before you play cards out here.  Jim Courtot there, who plans to rob you the shortest way, is a crook, a thief, a dirty liar and a treacherous man-killer.  He’s rotten all the way through.’

A man does not fire a fuse without expecting the explosion.  On the instant that Jim Courtot’s hand left his pile of coins, Alan Howard’s boots left the floor.  The cattleman threw himself forward and across the table almost with his last word.  Courtot came up from his chair, a short-barrelled revolver in his hand.  But, before he was well on his feet, before the short barrel had made its
