Books like Freckles

This book was written several generations ago. When I first read it (more than 40 years ago?) it was a bit dated already, but a basic coming of age plus love interest story, with a lot of tidbits about nature thrown in. Rereading it now, I found myself noticing the cultural differences between now and when it was written. Most noticeable were these: 1. Class stratification. Upper class people were just plain not supposed to even think about marrying those from the lower class, particularly if it was likely that they were bastards or not of good breeding.2. Good manners and ethics are apparently something that can be inherited, even if you were abandoned as an infant and raised in an orphanage. Good breeding will obviously overcome any "home environment".3. Clearing a swamp that is home to all kinds of rare animals, birds, insects, trees, etc, is progress, and that is a good thing. Yes, take photos of them first, and collect specimens, but do go ahead and clear the swamp.4. Shooting an otter so that its pelt could be made into a muff for a gift was a good idea. Nobody even considered whether the recipient might not have preferred to allow the otter to live.So this time instead of paying particular attention to all the tidbits about birds, trees, flowers, etc - I found myself reading it more like an historian or sociologist, and marveling at just how much American culture has changed in the last hundred years.
