Morris was distinguished as a teacher of undergraduates and was brought to Johns Hopkins to develop the collegiate instruction, which was modeled on the English system, as the graduate program was modeled on the German. His grammars presented his original views on teaching the ancient languages and his philological work was solid, but his greatest contribution was to the Hopkins undergraduates whom he selected for admission, guided carefully through the curriculum, and presented for the baccalaureate. He was particularly attracted to the history of Greece and was at work on an edition of Classen's Thucydides when he died.
