"Oh, for heaven's sake, Oscar!" exclaimed Jim disgustedly.
"Well, now," said Ames doggedly, "just why should sand-cement be stronger than the pure Portland?"
Jim scowled, started to speak with his old impatience, then changed his mind.
"You come up to the laboratory with me, Oscar. I'll give you a lesson on cement that will put a stop to this gossip at once. A man of your experience ought to know better."
Conflicting emotions showed in Oscar's face, boyish despite his fifty years. This was the first time Jim had used the man to man tone with Ames. He cleared his throat and followed the Big Boss up the trail to the little adobe laboratory. The young cement engineer looked curiously at Jim's companion.
"Mr. Field," said Jim, "this is Mr. Ames. He is one of the most influential men in the valley. He is giving practically all of his time to watching our work up here. He tells me the farmers feel that sand-cement isn't good. We will put in an hour showing Mr. Ames our tests and their results for the last five years, both here and on the Makon."
Field did not show his surprise at Jim's about-face. But he did say to himself as he went into the back room for his old reports, "Evidently the farmer is no longer to be told to go to Hades when he kicks. I wonder what's happened."
An hour later Jim and Oscar walked slowly up the trail toward Jim's house. Jim had invited Ames up for a further talk. Oscar had shown a remarkable aptitude for the details that Jim and Field had explained. And his pleasure at finally understanding the whole idea upon which Jim was basing his concrete work was such that Jim felt a very real remorse. He recalled almost daily questions from Oscar and other farmers that he had answered with a shortness that was often contemptuous.
"Now you see," Oscar said as they entered the cottage, "we'll actually save money on that. Wonderful thing, Mr. Manning, how mixing the sand and cement intimately enough, as you say, turns the trick. I'll tell the bunch down at Cabillo about that tomorrow."
