The number of these pavilions will depend on the number of Professors, and that of the Dormitories & Hotels on the number of students to be lodged & dieted.
This sentence is interesting to me; the pavilions on the lawn are very stately and large, and perfectly arranged around the lawn with no gaps or extra room. I wonder if Jefferson was operating under the assumption that there would always be a set number of professors and/or classes, which obviously has not been the case as the University has greatly expanded and now a very small fraction of professors employed here can expect to reside in a pavilion.
