I am honestly not sure how to use this particular book. It does have spelling words and vocabulary. There are also lessons on Latin Roots, dictation, parts of speech (like synonyms) and abbreviations.
This one contains stories like "King Solomn and the Bees", "Joan of Arc", and "Paul Revere's Ride" by Longfellow. This book does not seem to contain as many additional lessons like vocabulary.

The Catholic National Readers were originally published in the 1890s by Benziger Brothers Publishing. They have been reprinted by Savio Books and Neumann Press in 1997 in hardcover editions. They are frequently compared to the McGuffey's Readers and are illustrated with charming pictures of the sort you'd expect to see in "antique" books.
