i am,  those days eating beaver and porcupine . both have obvious big fat
content and their fat is also obviously , from taste and texture , rich in
polyunsaturated .(strong tasting fat ,  transparent yellow looking and very
runny .)
the natives from the east of canada who where eating them also had ample
supply of fresh water fishes .
