Lycksele Lappmark, 03/06/1732, ¶351:

I was also shown ‘Agaricus Abietis’ [fungus], which is the Lapps’ main remedy against mosquitoes and they use it to smoke both themselves and the reindeer.11 When the mosquitoes are numerous, the reindeer – even those that have been away the whole year – return home and small smoking fires are burned around them morning and evening. Knowing the efficacy of this, the reindeer lie down and sleep.
