You know, at that time we were using a product called M99 or etorphine to immobilize animals. That was relatively new at the time. It had been used, and used on bears. And so we loaded up the darts with the capture gun, and they were again, very helpful, showing me how to load the darts, and what. And the darts of course come in various sizes. You’d guess about the animal’s weight, and dose of how much you should use on it, and put it in the dart. It goes into the dart, you put a needle on the front, that can be various sizes. Some of them have barbs on them, some of them are just, are straight.
