The Fourth R by George O. Smith

Judge Carter insisted and won his point that James Holden accept residence in his home.

He did not turn a hair when the trucks of equipment arrived from the house on Martin's Hill; he already had room for it in the cellar. He cheerfully allowed James the right to set it up and test it out. He respected James Holden's absolute insistence that no one be permitted to touch the special circuit that was the heart of the entire machine. Judge Carter also counter-requested -- and enforced the request -- that he be allowed to try the machinery out. He took a simple reading course in higher mathematics, after discovering that Holden's machine would not teach him how to play the violin. (Judge Carter already played the violin -- but badly.)
