content: This is a series of correspondence, both addressed to Tyrrell from various contacts, as well as copies of letters he sent himself. Most of the correspondence is related to his engineering design and consulting work, such as his three-year relationship with and eventual termination from the Boston Bridge Company, and several design proposals submitted to general contractors. There is an exchange with a German engineering journal about one of his articles, as well as a reply to one of his book reviews.
