No, not “books rock” (even though they do). This is about stones.
I started reading at meals as a kid. Food and reading seem made for each other — both are at least potentially pleasurable activities, depending on the quality of what is being consumed.
Thing is, it’s hard to read while eating if your book refuses to stay open. (This, incidentally, is one area in which ebooks have an advantage over print). Some sort of weight is required, and pressing tableware into service for the purpose doesn’t work too well. The knife slides off, someone else needs the butter dish, etc.
Rocks, on the other hand, are perfect. And my house is full of them, ranging from small pebbles to large cobbles, due to a habit of picking up attractive rocks on beach walks.
Some rocks are better suited as book weights than others. Flat, rather than curved surfaces, and an elongated shape, are ideal qualities. As to weight, it depends on the springiness of the book, but something from a few ounces to a pound does the job admirably. Of course, you have to be careful; it’s not good to drop a hefty cobble onto a brand new, tightly glued paperback. A carelessly wielded stone may break the spine of a valued book.
Here are three reliable rocks I have used for years to keep books open.
The topmost one is the heaviest. Placed with care, it gently subdues any book that wants to snap shut when left unattended. The post header shows it in action, making my copy of The Egyptian Book of the Dead (a thick book with a tight spine) a little more readable. I found it by the South Saskatchewan River, near the town of Borden, in the 1980s. The middle one must have come from some beach here on Vancouver Island. Its shape was what made me pick it up; it’s less than half an inch (about 1 cm) thick, and an inch wide. It’s perfect for books that lazily flip up an unweighted leaf, and looks quite elegant when in use. The bottom one is a piece of greenish stone (possibly serpentine) from Ballenas Island in the Strait of Georgia. (OK, it looks grey in the picture, but trust me, it has a definite green tint, especially when wet. Looking good wet is something beach rocks do really well). I kept this rock on my desk at work, and used it to hold open books I was cataloguing. It’s a bit on the light side, so I’d have to position it in exactly the right spot. Sometimes the page would fight back, and the rock would slip off, requiring recovery and repositioning. Those white marks on the top two stones are eraser residue; rocks are also great eraser cleaners.
To be fair, there is another tool for holding books open — the “book snake,” an elongated cloth bag filled with dried beans or peas or similar stuff, or a weighted leather thing you can buy. I have no experience with either. Book snakes are said to be superior to rocks in that they are softer and shape themselves to the contours of a book, so will not mar pages. But you have to buy them or make them, whereas a suitably shaped stone is instantly ready for use. And it costs nothing.
Book rocks may also be used to crack nuts, or as weapons or missiles, should your dining situation deteriorate to the point that such items are required.
