R. G. Collingwood
Kirk excavated the fort of "Virosidum" at Bainbridge, North Yorkshire in 1925-26 with R. G. Collingwood. He excavated part of the Roman camp at Malton in 1927 with Philip Corder. The results of this excavation formed the core of the Roman archaeology collection of the Malton Museum. He and Corder also excavated at the side of Langton Roman Villa, near Malton, the excavations of which were led by Kirk. Regarding Kirk's role in the Langton excavations, Corder wrote: "The daily supervision and all the organisation of the work once again fell to Dr. Kirk, who directed the excavation in person, until ill health led to his forced retirement. Even then he largely directed the final stages of the work from his bed".
