It has been lost, the tribal knowledge in a lot of areas in husbandry or care of animals I think is being lost. There’s manuals on how to raise pups. There’s formulas, and you’ve gotta know where the sources are, obviously. With the internet today, you can find those things. But not only having the knowledge, you really need to pass on sort of the experience. You know, this pup in fact, there was a walrus pup born here earlier this spring, and it was nursing and doing very well. And Mike Boos, the general curator here, asked me, “Would you come and look at the pup?” because none of the staff had ever watched a pup born and nursing. They thought everything looked good.
