Interesting to watch!

Thanks for posting! That’s beautiful country; even in the older black-and-white film, you can really get an impression of how wild and pure and unspoiled it all is; you can almost smell the fresh, chill air coming off those waterfalls. But what primitive travel that last little bit! Almost a situation of "you can't get there from here". And this was still on Lake Superior, so not that far up.
I tried looking up “Uncle Tom’s Cabin” on Walloon Lake, and learned there is currently a 2,000 square foot cabin by that name, apparently for rent. Could it be the same one, 95 years later?
That’s an unusual hairstyle at 8:23, for that era; don’t think I’ve ever seen one like it.
What’s wrong with the man’s eyes at 15:32??

Is that the result of the insects being swatted away in the previous scene? Whatever it is, he seems to be placidly taking it in stride!
A very inventive ending! These were really well made for home movies. I'm trying to figure out how they got those letters to fly to him that way. Perhaps it was filmed in reverse, and he was removing the letters and tossing them toward the camera?
