Lyddie fights off a bear attacking their cabin in 1843.“Lyddie glared straight into the bear's eyes, daring him to step forward into the cabin.” This type of conflict is person vs nature, because bears occur to nature.
On a stagecoach to Lowell, Lyddie's fellow passengers were treating her with contempt, and refused to help her fix the broken coach. The conflict represented is person to nature, as multiple people belittle her.
Lyddie felt intimidated when seeing the large machines, having no idea how to operate them, and hearing the cacophony of the weaving room. "Her impulse was to run through the doors..." but if she wanted to earn money, she had to make acquiescence of the situation.
