 Hall also acted as adviser to the trustees for purchases for the gallery and art museum, and when the munificent bequest of Alfred Felton was received in 1904 his responsibilities were much increased.In 1905 Hall went to England to make purchases under the bequest.After his return he was expected to advise on everything submitted that might find a place in an art museum and, although he never claimed to be an expert in all these things, he supplemented his knowledge with hard reading and made relatively few mistakes.
