This fonds consists of two binders enclosing the typescript of a narrative called "Rivers of Ice, the Voyage of Captain George Tyson." When the safety of the ship is threatened by being crushed in the ice, a contingent take refuge on a large ice floe. The narrative follows their vicissitudes and ultimate rescue.

File includes 9 black and white photographs and 2 negatives of archaeological sites taken by Verschoyle Blake during a trip in Greece with Gilbert Bagnani and his mother in the Spring of 1923. Also included is a letter from Constance Marani to her friend Hester Thom dated 1 March 1926. Also, two typed pages of notes compiled by the donor and titled “Letter, March 1 1926 from (Ethel) Constance Marani née Blake, 1896-1979” with a genealogical focus, and “Verschoyle Benson Blake 1899-1971”, also with a genealogical focus. Verschoyle Blake helped the Bagnanis, Gilbert and Stewart, whose papers are located in Trent University Archives, with the architectural design of a library in their Port Hope, Ontario house, Vogrie.

File consists of two copies of Katherine E. Wallis: Canadian Sculptor by A. Roger Collins. One copy is inscribed "Dear Aunt Elise with much love from 'Alas!' and 'Alack!,' Happy Memories, 1949". Elise may refer to Elise Roux (1853-1953), wife of Thomas Alexander Stewart Hay (son of Dr. Thomas Hay and Anna Maria Stewart). Loosely inserted is an unidentified photograph of a woman.
The second copy is inscribed "Helen Dear for the new house, Love from Alice, 1953". Helen may refer to the donor's aunt, Helen Frances Mathias who married Rod Stuart; Alice may refer to the author, Alice Roger Collins.

File also includes two removable flash memory devices containing Dr. Mathias' PhD dissertation as well as digital images, slides, and photographs linked to archaeology work conducted by Mathias in Newfoundland, Qatar and Afghanistan. The dissertation provides context for the images.

File includes 17 photographs of archaeological sites in Greece, some identified as Monemvasia, believed to have been taken by Blake while accompanying archaeologist Gilbert Bagnani on a dig in 1923. Also included are 21 photographs of medieval and 16th-17th century French streets and houses; it is probable that these relate to Blake’s own research or to that of Gilbert Bagnani.
