Ralph was in high spirits. Having the material for nothing, and water in abundance, he was able to manufacture his concrete even cheaper than he had calculated. In fact, his profits were so good that he increased the wages of his hands all round, and got more work out of them in consequence.

Robert Telfer, however, who was much more of a man of the world than Ralph, was by no means satisfied with the condition of affairs. He foresaw contingencies that never occurred to the younger man.

"Look here," he said to Ralph one day, "you ought to turn out much more stuff than you are doing."

"Impossible," Ralph answered. "I have so many men at work that they are getting in each other's way as it is."

"But why not double your shifts? Let one lot get in at six and break off at two, and the second come in at two and leave off at ten."

"I never thought of that," Ralph answered.

"Well, you take my advice. There's an old proverb, you know, about making hay while the sun shines."

"But the sun will shine as long as you take my concrete."

"Don't be too sure of that."

"How?" Ralph said, glancing up with questioning eyes.
