Author of Spelling book:

I am convinced that 'Spelling' is by Peter Jones, as he was commissioned to put together a spelling book on June 2, 1828, and presented the manuscript to a printer in York on June 19, 1828, for the Methodist Indian Missionary School he ran, which Conference Missionary Society was a Methodist society. Also, in his book Life and journals of Kah-ke-wa-quo-na-by, in the journal entry for the 19th, it says, "Arrived at York in the afternoon, and commenced getting a small Indian spelling book, which I had written, printed at Mr. McKenzie's office." and considering "Spelling" was only 12 printed pages—3 sheets of paper—that, I think, does qualify as "a small Indian spelling book."

Syncope:

Several words are presented in a partial syncope form. For example, gagiina­wishkiwin to mean a fib, a lie or a falsehood, in the partial syncope form is ggiina­wishkiwin, and the full syncope form is ggiinwishkwin. Summerfield presents this word as Kenah­weskewin, n. falsehood, which seems to match the partial syncope form of the word. However, if this partial syncope is noted, so should the dozen or so other words shown in partial syncope.
