The speckled blue paper cover of this notebook drew me to it, but it's the bird drawing on the inside of the front cover that sold me, with the words "Bird of the air No.2" trailing down. (My first photo is a composite of cover and first inside page.) Having now spent a little time with it's pages, I've determine that the John C. Mendell who kept it was a kindred spirit--a terrible note-taker it looks to me, instead filling the pages with names and scribbles and bits of this or that, maybe occasionally jotting a few references to a lesson. I found a John C. Mendall 1844-1871 of Rochester, MA, who I would guess was the owner of this, dating it to the 1850s, which seems right. 

8" x 6 7/8"; 10 pages filled front and back plus cover. Tears to the lower corner of front cover and a couple of inside pages plus one partial page, but overall good condition.
