Out of the Silent Planet - C. S. Lewis [75]
By the way, while we are on the subject of species, I am rather sorry that the exigencies of the story have been allowed to simplify the biology so much. Did I give you the impression that each of the three species was perfectly homogeneous? If so, I misled you. Take the hrossa; my friends were black hrossa, but there are also silver hrossa, and in some of the western handramits one finds the great crested hross - ten feet high, a dancer rather than a singer, and the noblest animal, after man, that I have ever seen. Only the males have the crest. I also saw a pure white hross at Meldilorn, but like a fool I never found out whether he represented a sub-species or was a mere freak like our terrestrial albino. There is also at least one other kind of sorn besides the kind I saw - the soroborn or red sorn of the desert, who lives in the sandy north. He's a corker by all accounts.
I agree, it is a pity I never saw the pfifltriggi at home. I know nearly enough about them to 'fake' a visit to them as an episode in the story, but I don't think we ought to introduce any mere fiction. 'True in substance' sounds all very well on earth, but I can't imagine myself explaining it to Oyarsa, and I have a shrewd suspicion (see my last letter) that I have not heard the end of him. Anyway, why should our 'readers' (you seem to know the devil of a lot about them!), who are so determined to hear nothing about the language, be so anxious to know more of the pfifltriggi? But if you can work it in, there is, of course, no harm in explaining that they are oviparous and matriarchal, and short-lived compared with the other species. It is pretty plain that the great depressions which they inhabit are the old ocean-beds of Malacandra. Hrossa, who had visited them, described themselves as going down into deep forests over sand, 'the bone-stones (fossils) of ancient wave-borers about them.' No doubt these are the dark patches seen on the Martian disk from Earth. And that reminds me - the 'maps' of Mars which I have consulted since I got back are so inconsistent with one another that I have given up the attempt to identify my own handramit. If you want to try your hand, the desideratum is 'a roughly north-east and south-west "canal" cutting a north and south "canal" not more than twenty miles from the equator.' But astronomers differ very
