Second only to her father's was Helen's eager interest in the world about her. The ride back to Desert Valley through the rich moonlight was an experience never to be forgotten. She and Howard alone in what appeared an enchanted and limitless garden of silence and of slumber, their horses' feet falling without noise as though upon deep carpets, the bright moon and its few attendant stars working the harsh land of the day over into a soft sweet country of subtle allurement--the picture of all this was to spring up vivid and vital in many an idle hour of the days to follow. Little speech passed between them that night: they rode close together, they forgot the wagon which rocked and jolted along somewhere far behind them; they were content to be content without analysing. And at the end of the ride, when she felt Alan's strong hands aiding her from her saddle, Helen sighed.
The next morning early she and her father left Desert Valley, going straight to the professor's destination in the Last Ridge country. They did not see Howard, who had breakfasted and ridden away before dawn, leaving with the kitchen boy a brief note of apology. The note said that his business was urgent and that he would call to see them in a day or so; further that Tod Barstow and Chuck Evans had orders to haul their goods in the wagon for them and to help them pitch camp.
