White had a huge blackboard installed on the cellar wall opposite the machine, and he proceeded to fill the board with block outlines filled with crabbed writing and odd-looking symbols. The whole was meaningless to James Holden; it looked like the organization chart of a large corporation but it contained no names or titles. The arrival of each new visitor caused changes in the block diagram.

These arrivals went at their project with stop watches and slide rules. They calibrated themselves and James with the cold-blooded attitude of racetrack touts clocking their favorite horses. Where James had simply taken what he wanted or what he could at any single sitting, then let it settle in his mind before taking another dose of unpremeditated magnitude, these fellows ascertained the best effectiveness of each application to each of them. They tried taking long terms under the machine and then they measured the time it took for the installed information to sink in and settle into usable shape. Then they tried shorter and shorter sittings and measured the correspondingly shorter settling times. They found out that no two men were alike, nor were any two subjects. They discovered that a man with an extensive education already could take a larger sitting and have the new information available for mental use in a shorter settling time than a man whose education had been sketchy or incomplete.

They brought in men who had either little or no mathematics and gave them courses in advanced subjects. Afterwards they provided the foundation mathematics and they calibrated and measured the time it took for the higher subject to be understood as it aligned its information to the whole. Men came with crude English and bluntly read the dictionary and the proper rules of grammar and they were checked to see if their early bad-speech habits were corrected, and to what degree the Holden machine could be made to help repair the damage of a lifelong ingrained set of errors. They sent some of these boys through comparison dictionaries in foreign tongues and then had their language checked by specialists who were truly polylingual. There were some who spoke fluent English but no other tongue; these progressed into German with a German-to-English comparison dictionary, and then into French via a German-to-French comparison and were finally checked out in French by French-speaking examiners.

And Professor White's block diagram grew complex, and Dr. Persons's histograms filled pages and pages of his broad notebooks.

It was the first time that James Holden had ever seen a team of researchers plow into a problem, running a cold and icy scientific investigation to ascertain precisely how much cause produced how much effect. Holden, who had taken what he wanted or needed as the time came, began to understand the desirability of full and careful programming. The whole affair intrigued him and interested him. He plunged in with a will and gave them all the help he could.

He had no time to be bored, and he did not mark the passage of time until he arrived at his thirteenth birthday.

Then one night shortly after his birthday, James Holden discovered women indirectly. He had his first erotic dream.

We shall not go into the details of this midnight introduction to the arrival of manhood, for the simple reason that if we dwell on the subject, someone is certain to attempt a dream-analysis and come up with some flanged-up character-study or personality-quirk that really has nothing to do with the mind or body of James Holden. The truth is that his erotic dream was pleasantly stirring, but not entirely satisfactory. It was fun while it lasted, but it didn't last very long. It awakened him to the realization that knowledge is not the end-all of life, and that a full understanding of the words, the medical terms, and the biology involved did not tell him a thing about this primary drive of all life.

His total grasp of even the sideline issues was still dim. He came to a partial understanding of why Jake Caslow had entertained late visitors of the opposite sex, but he still could not quite see the reason why Jake kept the collection of calendar photographs and paintings hung up around the place. Crude jokes and rude talk heard long years before and dimly remembered did not have much connection with the subject. To James Holden, a "tomato" was still a vegetable, although he knew that some botanists were willing to argue that the tomato was really a fruit.

For many days he watched Judge Carter and his wife with a critical curiosity that their childless life had never known before. James found that they did not act as if something new and strangely thrilling had just hit the known universe. He felt that they should know about it. Despite the fact that he knew everything that his textbooks could tell him about sex and copulation he still had the quaint notion that the reason why Judge Carter and his wife were childless was because they had not yet gotten around to Doing It. He made no attempt to correlate this oddity with its opposite in Jake Caslow's ladies of the night who seemed to go on their merry way without conceiving.
