"What would the numbers be for the first one, hydrogen?"
"Period One, Group One. One electron shell, one electron in the outer shell," Tranter told her. "Helium's period one, too, but it has the outer—only—electron shell full, so it's in the group of inert elements."
"Trav, Trav. Trav's the first month of the year. And helium's Trav, Yenth; Yenth is the eighth month."
"The inert elements could be called Group Eight, yes. And the third element, lithium, is Period Two, Group One. That check?"
"It certainly does. Sanv, Trav; Sanv's the second month. What's the first element in Period Three?"
"Sodium. Number Eleven."
That's right; it's Krav, Trav. Why, the names of the months are simply numbers, one to ten, spelled out.
"Doma's the fifth month. That was your first Martian word, Martha," Penrose told her. "The word for five. And if davas is the word for metal, and sornhulva is chemistry and / or physics, I'll bet Tadavas Sornhulva is literally translated as: Of-Metal Matter-Knowledge. Metallurgy, in other words. I wonder what Mastharnorvod means." It surprised her that, after so long and with so much happening in the meantime, he could remember that. "Something like 'Journal,' or 'Review,' or maybe 'Quarterly.'"
"We'll work that out, too," she said confidently. After this, nothing seemed impossible. "Maybe we can find—" Then she stopped short. "You said 'Quarterly.' I think it was 'Monthly,' instead. It was dated for a specific month, the fifth one. And if nor is ten, Mastharnorvod could be 'Year-Tenth.' And I'll bet we'll find that masthar is the word for year." She looked at the table on the wall again. "Well, let's get all these words down, with translations for as many as we can."
"Let's take a break for a minute," Penrose suggested, getting out his cigarettes. "And then, let's do this in comfort. Jeff, suppose you and Sid go across the hall and see what you find in the other room in the way of a desk or something like that, and a few chairs. There'll be a lot of work to do on this."
