Boston, MA, EEF committee
The Reverend Copley Winslow was instrumental in collecting subscriptions and interesting American institutions in the work of the EEF. It is likely this refers to his house, at 527 Tremont Temple Street, which served as the office for the EEF. It is possible that the objects bound for the offices were meant to be distributed to institutions or smaller concerns like schools or perhaps for comittee members.
At the begining of the 20th century subscriptions from America were less reliable on account institutions and universities had started funding their own excavations, this was also aided by Winslow's erratic behaviour and accusations against the London office and against the secretary of the US branch, Marie Buckman.
