I have been priviledged to live at one time or another where all of these species thrive. Once the chestnut trees (a major component of our eastern American hardwoods at one time) was almost eradicated by disease, the oaks took over as the prevalent hardwood in many areas. I feel confident in saying that this reader was in use well before the 1900’s. I got this little book because I found the illustrations to often be quite interesting, varying in size from 1”x1” (like engravings from the British chapbooks) to 3 ?”x 2 ?” and for the most part, if not all, were done specifically for this book. The only word I can decipher from the cover is “Reader” and there is no title page. The preface states that they are striving to give enough illustrations to capture and hold the interest of children just learning to read, and they hoped the subject matter would appeal as well. The first page begins as “School Reading, Second Year.”
