The oil I got out of the frozen oil sacs is cream colored, I almost got a headache looking for hair! Gonna grind the empty sacs and see if I can find some hair?! I thought I knew something about beaver and smells?

I have found a good amount of hair in the oil sacs I have cleaned. So much so I keep a pair of tweezers handy to pick them out of the drained oil as best I can. The hairs pull out easily, not seeming to be attached within the oil sac. I will look better the next batch of sacs that I drain.

I've also not seen any attached.

I like to put a layer of salt in a glass bowl. Layer of whole sacs then a layer of salt. Keep going till the bowl is full. After awhile everything is stable. The salt takes on some of the oil. Is both an attractant and preservative. The sacs get dried and hard. Run them through my grinder and add to bait. When rain is being a royal pain fresh glands squeezed out in a flat set wont wash off. Not a great lure for predators but it keeps working. Predators like to have a sniff or two. Catch's beaver pretty good. I just make a slick spot on the bank. Put oil in the slick spot and and peel a few willow sticks and toss them on the bank.
