John Morison of Windham, New Hampshire, compiled this mathematical cypher book, containing extensive notes and practice problems on sailing, surveying, trigonometry, accounting, weights and measures, arithmetic, algebra, fractions, decimals, geometry, geodesia, and navigation. Many of the signatures are of different-size paper and stitched together using different thread. The final signature is upside down from the rest of the volume and contains penmanship practice, poetry, a song, scattered family names, miscellaneous figures, and drawings (including a windmill).

Leo Engleman worked trigonometric and surveying exercises in this cypher book from 1847 to 1848, possibly while a thirteen-year-old boy living in Pennsylvania. Many of the exercises include mathematical drawings and illustrations, and surveying examples often include additional features done in pencil and watercolor.

Leo Engleman worked trigonometric and surveying exercises in this cypher book from 1847 to 1848, possibly while a thirteen-year-old boy living in Pennsylvania. Many of the exercises include mathematical drawings and illustrations, and surveying examples often include additional features done in pencil and watercolor, such as trees, rivers, buildings, and lighthouses. A number of headings also feature watercolor embellishments and abstract or geometric designs, and the final pages of the volume include full-page watercolor designs of geometric shapes and a rose bush.

In this book, a traveling New England schoolteacher recorded instructional exercises, instructional explanations, poetry, and biographical information about pupils. The author taught in New Hampshire and present-day Maine. Subjects of instruction include arithmetic, surveying, geometry, nautical navigation, and writing.

A traveling New England schoolteacher recorded instructional exercises, instructional explanations, poetry, and biographical information about pupils in this volume (220 pages, 8" x 12") between 1787 and 1811. The author taught in New Hampshire and present-day Maine and entered personal information about teaching appointments throughout the volume. Individual lessons are dated as early as 1787, and the volume includes several lists of male and female pupils from teaching engagements in various towns, dated as late as 1811. Some lists of students are accompanied by the students' birthdates. Classes convened in schoolhouses, other public structures, and private homes.

Each page has a subject label, and several pages are comprised of miscellaneous questions entitled "A Collection of Questions," occasionally attributed to The London Magazine. Much of the volume pertains to instruction in mathematical subjects such as algebra, geometry, and trigonometry, and it includes diagrams, examples, and practical applications. Lengthy sections are devoted to surveying and nautical navigation (including "plane-sailing"), often with many diagrams. Other sections concern subjects such as writing and history, with examples of proverbs, deeds, marriage licenses, and letters for copying. Some pages have collections of anecdotes, proverbs, and poems, usually pertaining to morality and religion. A number of lengthier poems concern death and weddings, and one is entitled "Rodgers & Victory[:] Tit for tat. Or the Chesapeake paid for in British Blood!!!" Other parts include a cure for jaundice, a "rebus," a table of symbols for astronomical objects, information about "Occult Philosophy or Magic," instructions for gauging a copper kettle and a man of war, and a list of nouns with corresponding verbs and participles. Some of the material is copied from outside sources, such as John Love's Geodesia.
