Saints teaches "seer stones" instead of "Urim and Thummim"

The book Saints, volume 1, deliberately misleads readers by teaching them revisionist history. Here's another blatant example.

The book falsely describes the Urim and Thummim as "seer stones," a term Joseph never applied to them.

Beneath the boulder was a box, its walls and base made of stone. Looking inside, Joseph saw the gold plates, seer stones, and breastplate.19 

(Vol 1: 1815–1846, Part 1, Chap 3: Plates of Gold, ¶28 • 1:25–26)

The footnote:

19 Joseph Smith—History 1:52; Joseph Smith History, 1838–56, volume A-1, 7, in JSP, H1:232 (draft 2). Topic: Gold Plates

52 Having removed the earth, I obtained a lever, which I got fixed under the edge of the stone, and with a little exertion raised it up. I looked in, and there indeed did I behold the plates, the Urim and Thummim, and the breastplate, as stated by the messenger. The box in which they lay was formed by laying stones together in some kind of cement. In the bottom of the box were laid two stones crossways of the box, and on these stones lay the plates and the other things with them.

(Joseph Smith—History 1:52)

I looked in and there indeed did I behold the plates, the 

Urim and Thummin

 and the Breastplate as stated by the messenger.
