The "Data on Winter Communication" scrapbook contains clippings about ferry service from a variety of Prince Edward Island newspapers from 1897 to 1903. Many of the articles and letters from citizens argue about where the ferries should cross the Northumberland Strait.

During this time period the steamship ice-breaker the "Stanley" and then also the "Minto" were providing passenger, mail and supply service between Prince Edward Island and the mainland. The newspaper clippings are glued into a copy of the "Fourteenth Annual Report of the Bureau of Animal Industry" (1897). Pages that did not have clippings glued on them were cut out at some point.
