He took a pencil from his leather case and tapped it against his notebook as he ruffled the pages, wondering how to begin. It was hard to think logically when a part of his mind was in such confusion. Had Leah been listening in to all of his phone conversations? If so, it was fortunate that he had long ago devised an emergency code. Was it only idle curiosity that had prompted her or was she acting under orders? Was anyone else watching him, he wondered, listening to his talk, perhaps even checking the routine of his experimental work? There was Lanza this morning—why had he come unannounced, in person, when a Communications call would have served the purpose equally well?
Leah's voice broke in. "I'm ready, Dr. Wong."
He cleared his throat. "...the Summer Seminar. Title: The Propogation of White Martian virus. Paragraph. It will be remembered that the early attempts to establish Earth colonies on Mars were frustrated by the extreme susceptibility of our people to two viruses native to the foreign planet, viruses which we designate as Blue Martian and White Martian, according to the two distinct types of fever which they cause. Blue Martian Fever in the early days caused a mortality among our colonists of nearly eighty-five per cent, and made the establishment of permanent colonies a virtual impossibility.
"Under the inspired leadership of Leader Marley and with the advice of his deputy Dr. Lanza, this laboratory in Research worked out a method of growing the virus and producing an immunizing agent which is effective in nearly all human beings. Only the cooperation of several Categories made possible such a feat. It will not be forgotten that even the humblest helpers in the Institute had their share in the project, that some of them acted as human volunteers in the experiments, well knowing the risks they ran, and were afterward rewarded by a Free Choice.
"One person in Office Category, for instance, was given the privilege of learning to play the flute, although nobody in his family had ever belonged to Music, and another person in Menial Category was permitted a month's study of elementary algebra, a nearly unheard of indulgence for a person in his position. But as Leader Marley so graciously remarked in conferring the awards: To the individual who risks much, the State gives much."
"Like me and Tanya?" the girl asked, stopping her typing.
"Yes, like you and Tanya. You were allowed to act a part in an amateur Theater group, I remember, and since Tanya was made too ill to be able to use a Free Choice, she was sent out west to the Playground, just as though she had belonged to Ruler Category. Now where was I?"
"'The State gives much.'"
"Oh, yes. Paragraph. Since the discovery of the immunizing mechanism to Blue Martian, permanent colonies have been established on Mars. But there remains the more elusive problem of White Martian Fever, which, though its mortality is only thirty per cent, is still so crippling to those victims who survive that the Martian colonies cannot begin to expand, and the resources of the planet cannot be fully developed, until an immunizing agent is found.
"For the past eight years this laboratory has been working at the problem, among others, and we are now in a position to report a small degree of progress. Since it proved to be impossible to grow the virus in the usual media, it occurred to us—"
