‘We are going the same way, friend,’ he said as he looked up.  ’What is more, we are going over a trail I know by heart.  There is a good chance I can save you time and trouble by making it a party of three.  Am I wanted?’

‘It is extremely kind of you,’ said Longstreet appreciatively.  ’But you are on horseback and we travel slowly.’

‘I can spare the time,’ was the even rejoinder.  ’And I’ll be glad to do it.’

During the half-hour required to break camp and pack the two horses, Alan Howard gave signs of an interest which now and then mounted almost to high delight.  He made no remark concerning the elaborate system of water-bottles and canteens, but his eyes brightened as he aided the professor in making them fast.  When the procession was ready to start he strode on ahead, leading his own horse and hiding from his new friends the widening grin upon his face.

The sun was up; already the still heat of the desert was in the air.  Behind the tall rancher and his glossy mare came Professor Longstreet driving his two pack animals.  Just behind him, with much grave speculation in her eyes, came Helen.  A new man had swum all unexpectedly into her ken and she was busy cataloguing him.  He looked the native in this environment, but for all that he was plainly a man of her own class.  No illiteracy, no wild shy awkwardness marked his demeanour.  He was as free and easy as the north wind; he might, after all, be likeable.  Certainly it was courtois of him to set himself on foot to be one of them.  The mare looked gentle despite her high life; Helen wondered if Alan Howard had thought of offering her his mount?

They had come to the first of the low-lying hills.

‘Miss Longstreet,’ called Howard, stopping and turning, ’wouldn’t you like to swing up on Sanchia?  She is dying to be ridden.’

The trail here was wide and clearly defined; hence Longstreet and his two horses went by and Helen came up with Howard.  Hers was the trick of level, searching eyes.  She looked steadily at him as she said evenly: 

‘So her name is Sanchia?’

For an instant the man did not appear to understand.  Then suddenly Helen was treated to the sight of the warm red seeping up under his tan.  And then he slapped his thigh and laughed; his laughter seeming unaffected and joyous.

‘Talk about getting absent-minded in my old age,’ he declared.  ’Her name did use to be Sanchia; I changed it to Helen.  Think of my sliding back to the old name.’

Helen’s candid look did not shift for the moment that she paused.  Then she went on by him, following her father, saying merely: 

’Thank you, I’ll walk.  And if she were mine I’d keep the old name; Sanchia suits her exactly.’

But as she hurried on after her father she had time for reflection; plainly the easy-mannered Mr. Alan Howard had renamed his mare only this very morning; as plainly had he in the first place called her Sanchia in honour of some other friend or chance acquaintance.  Helen wondered vaguely who the original Sanchia was.  To her imagination the name suggested a slim, big-eyed Mexican girl.  She found time to wonder further how many times Mr. Howard had named his horse.
