“Seth material” search engine (Jane Roberts)

There are multitudinous species of viruses and so forth that man has not encountered and recognized, and there are connections between viruses and other species of living matter that remain unknown. There are indeed two different kinds of upward-walking mammals, much like your own species, but much larger, and with infinitely keener senses. They are indeed amazingly swift creatures, and through scent alone they are aware of the presence of man when any member of your species is at all in the immediate area — standing, say, at least several miles away. Vegetable matter is a main diet, though often supplemented by insects, which are considered a delicacy.

(Pause at 4:40.) Offspring do not occur until the individuals are well past the age that you would consider normal for breeding. Otherwise the procedure is the same. With some territorial variation, such creatures reside in many of the world areas on your planet, though their overall population is very small — altogether, perhaps, several thousand. They rarely congregate in large groups, but do have a family and tribal-like organization, with at the very most twelve adults in any given area. As offspring are added, the groups break up again, for they know well that in larger numbers they would be much more easy to discover.
