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.
