 While in prison, writing under the name "Hercules", he published fourteen essays on the idea of the canal from the Hudson River to Lake Erie; they appeared in the "Genesee Messenger".Considering his modest education and lack of formal training as an engineer or surveyor, Hawley's writing was remarkable; he pulled together a wealth of information necessary to the project, provided detailed analysis of the problems to be solved, and wrote with great eloquence and foresight on the importance the canal would have to the state and to the nation.Though they were deemed the ravings of a madman by some, Hawley's essays were to prove immensely influential on the development of the canal.
