Can anyone tell me what this means?

Hello！Sorry to bother you again. But I really need your help making sense of this following sentence:

"For Florence, if you please, gaining in time a more composed view of nature, and overcome by her habits of garrulity, arrived at a frame of mind in which she found it almost necessary to tell me all about it--nothing less than that. "

The part that perplexed me the most is "a more composed view of nature". I'm not so sure what the author is getting at here. Does it mean that she (Florence) feels more comfortable with who she is now? or does "nature" here refer to something else? Like human nature in general?

Please tell me what you think. Thank you!
