There was a lot of marshy country and importantly huge mosquitoes. I said to Kirsten, 'Don't worry about mosquitoes, I know all about them'. You don't know about north Norway's mosquitoes because what happens is of course that with the reindeer moss being covered by snow for several months of the year, then the sun comes out and it's way past the Arctic Circle so it just stews in the sunlight for 24 hours a day. The mosquitoes love it and they grow accordingly. They are looking for food and what better than half a dozen idiotic travellers. So we had nets. We had to use mosquito oil and we found that when we had to trade with the Lapps they weren't interested in money. They could get their own food. What they wanted was mosquito oil because they were plagued by this as well, and what we used was called DIMP, it's dimethyl phthalate was the mosquito repellent of the day.
