Well that was in packaging. I took over the packaging research unit. Well, lets go back to [packaging research later]---anyway, when Ken Brown left and Necmi was here, the other side issue was I worked a lot on this polysulfide pulping for about four years, but then we also were having at that time a lot of cooperative work with industry, and I really liked this cooperative work with industry because it was, well they have a definite [short-term] objective. It was like evaluating a species or evaluating a process, or making a certain product or something like that. It was usually of short duration you know, like three or four months at a time, so it provided a lot of change, which I liked. I liked the change part of it you know rather than every day the same old thing, polysulfide pulping.
