During lunch, stopped in to Green Leaf Books, on Stone. It is a pleasing bookstore. Used and new. I resisted Keep Chickens!, but ended up with The Orchard Mason Bee instead, and find that I can house them in a four-by-six drilled with 5/16" holes -- can just hang it out there and with luck they'll find it -- but in April or May. Be aware also that "one species [of bee] nests only in the spiraled labyrinth of the abandoned shell of a particular species of snail." Green Leaf has plants, gardening, natural history; food, cooking; a section of children's books; also a smattering of other books, mixed together, and seeming to include more interesting ones than is likely. Bright and airy. Ordinarily I don't approve of such non-shelf use of wall space and cubic yardage, but I'm won over.
