Our wooden, tin-roofed house in Sinajaña in the 1960s did not have air conditioning. Which meant we slept with the windows open. Which meant that the ñåmo (mosquitoes) could come in at will. We had screens on our windows, but mosquitoes could still come in somehow.
So, we had mosquito coils burning at night to keep them away.
Can I confess that I actually liked the smell of mosquito coil?
Before the Stores Sold Mosquito Coils
Our mañaina used oddo', fibrous parts of tree trunks, like niyok (coconut) to smolder, create smoke and chase the ñåmo away.
In Luta and Saipan before the war, the Japanese stores sold mosquito coils, which in Japanese is senko (incense stick). So, the people of Luta and Saipan call it sengko'.
