George Gilbert kept this volume from 1848 to 1862, writing diary entries and other documentation relating to his work as an itinerant teacher, primarily in Pennsylvania and Maryland. He also recorded various financial transactions, including matters relating to agricultural labor in Massachusetts.

George Gilbert kept this volume from 1848 to 1862, writing diary entries and other documentation relating to his work as an itinerant teacher, primarily in Pennsylvania and Maryland. He also recorded various financial transactions, including matters relating to agricultural labor in Massachusetts.

Diary entries are scattered throughout the volume in a non-chronological fashion, spanning April 1852 to November 1854, reflecting George Gilbert's studies and work as an itinerant teacher in Easthampton, Massachusetts; Tyburn, Pennsylvania; Richboro, Pennsylvania; and Perrymansville, Maryland. He frequently commented on the weather and agriculture of the region, the people in the communities, the quality of the students who attended his schools, and his uncertainty about where he would teach next. He often compared the locales to Massachusetts, where he lived previously, and wrote disparagingly of the students. On June 30, 1853, Gilbert recounted a portion of his teaching history to that point and commented on notable students, primarily those who struggled with learning or who had physical disabilities. He noted one student who was deaf.

Gilbert's diary entries also reveal glimpses into his social life. He recorded events like news of Louis Kossuth visiting North Hampton (April 24, 1852); Jenny Lind performing a concert (May 6, 1852); attending a re-enactment of a Revolutionary War battle (December 25, 1852); boarding at a tavern (August 28, 1853); attending a spirit rapping (September 19, 1853); and frequenting churches. At least two references appear to be related to the woman he would go on to marry, Jane Phelps. Gilbert also wrote sparingly on race and ethnicity, including mentions of an Irish student, passing an African American church (October 23, 1853), and Christmas celebrations where he noted distributing candy to African American children (December 25, 1853).

Early in the volume, George Gilbert listed out the names of students he taught in various places, including Oakham, Palmer, Perrinton, West Greece, Tyburn, Richboro, and Perrymansville. On several occasions, he also recorded the students' ages, which ranged from three to 22.

Gilbert used the volume for various other purposes. An ink impression of a leaf appears near the front of the volume. Notes about financial transactions, such as boarding, wages, and expenses are also included throughout. Later accounts indicate Gilbert may have turned to agricultural work in West Brookfield by 1856. Gilbert copied a warranty deed from 1853 regarding the sale of land in West Brookfield between Bostwick Gilbert and Avery Keep. Two illustrations were drawn into the volume, one of which represents the workings of a water wheel.

The Gerald T. and Charlotte B. Maxson printed ephemera collection contains over 5,000 pieces of assorted ephemera, the majority of which were commercially printed in the United States during the mid to late 19th-century.

The Maxson collection provides a valuable resource for the study of 19th-century visual culture, commercial advertising, and humor in addition to the role of gender, ethnicity, and race in advertising. American businesses are the predominant focus of the collection, though many international businesses are also represented. While trade cards are by far the most prevalent type of ephemera found in this collection, an extensive array of genres are present including die cut scrapbook pieces, photographs, engravings, maps, serials, and manuscript materials.

The 23 binders that house the Maxson collection were arranged by the collectors themselves. Items are organized somewhat randomly in terms of topical arrangement. While pockets of related materials can be found here and there (for instance, the entirety of Volume 16 contains circus-related items while Volume 11 contains an extensive number of Shaker-related materials), for the most part any given subject may appear in any given volume. In some cases, items are clustered as a result of having been acquired together or due to a documented common provenance. Occasional typed annotations written by the Maxsons help provide additional context for certain items.

The Maxson Collection Subject Index serves as a volume-level subject index for materials found throughout the binders. The subjects indexed here are generally representative of both visual and commercial content. In addition to more general subjects, many names of specific people, places, buildings, events, and organizations that appear in the materials have also been listed. Researchers engaging with this collection should be aware that they will encounter numerous examples of racist caricatures, especially ones depicting African American, Native American, Irish, and Chinese people.

This collection is comprised of 53 letters addressed to Sophie Hoffman McLane, her daughter, Sophie, and her husband, Louis. Sophie received 12 letters from female friends between 1839 and 1849; her husband Louis received 3 letters in 1866; and her daughter Sophie received 9 letters from family members between 1871 and 1876. The collection also contains 29 undated letters addressed to either Sophie Hoffman McLane or her daughter of the same name, primarily from the elder Sophie's mother, E. Hoffman, and from female friends in Baltimore, Wilmington, and Philadelphia. Most letters concern the social and family lives of women in Maryland, Pennsylvania, and Delaware during the mid-19th century. One item is a set of "True Lovers Knots (in grass & in ribbon)."

The first 12 items, and most of the undated items, are personal letters Sophie Hoffman McLane received from female acquaintances prior to her marriage, mostly dated in 1839 and between 1847 and 1849. The writers discussed aspects of their lives in Philadelphia, Pennsylvania, and Wilmington, Delaware, including family news, social events, and relationships between men and women. The women traveled in similar social circles and frequently mentioned the same mutual acquaintances. Among Sophie's most frequent correspondents were Mary A. Robeson (15 letters), Kate Milligan (6 letters), and her mother, E. Hoffman (8 letters). In the fall of 1866, her husband, Louis McLane, received 3 letters from friends in San Francisco, who wished him luck after hearing of his anticipated return to New York. Later letters, dated between 1871 and 1877, are primarily addressed to the younger Sophie McLane, including 4 letters from her father, Louis McLane, and 5 from her sister, Kate M. McLane (including letters from San Francisco). Both provided family news, such as updates on a newborn baby, and discussed traveling.

The collection's first letter is about the experiences of a woman named Ellen, who was visiting Paris (August 9, 1839). Two letters concern the birth of Charles McLane: Kate M. McLane's account (August 1, 1871), and Louis McLane's report of his health (August 17, 1871). Kate McLane wrote her sister Sophie about her experiences at the Centennial Exhibition in Philadelphia, Pennsylvania. (November 3, 1876, 22 pages). Kate also drew a small diagram of a piece of machinery.
