This is a delightful old book (1940) by Charles Lee; I found a copy of it, signed by the author, in a used bookstore in Quebec (I think it was) a few years ago. It has a chapter for each month, full of delightfully old-fashioned book trivia, lists and occasionally quotes, somehow related to that month. I've read January's a few times :) but this year decided to work through it - and as with everything going on I hadn't read March yet, I have been today. It references Walden: 'it was during the month of "stormy March" ' when Thoreau started cutting wood for his cabin. I thought I had a copy of Walden - turns out I don't, or I can't find it, but I did find one of his other books on my shelves, The Maine Woods, a hardback published in 1950 that's a compilation of several of his travels in that area, and began in on that.
If you find yourself really hankering to read Walden, it is probably available as a free ebook online. I'm going to look up "The Maine Woods," as I hadn't heard of that one. Thanks and happy reading!
