 Within a year, enough funds had been raised to hire four full-time collectors, and with that the "Mammal Survey" began.Lasting 12 years, the survey helped build collections that became the basis for R.I. Pocock's two volumes, "Mammalia", in the series" The Fauna of British India, Including Ceylon and Burma".Both the commencement and the success of the survey depended largely on Millard's fund-raising and organizational work; this, he undertook in addition to his work as editor of the "Journal" and as manager of his employer's wine business, Messrs. Phipson and Co.

Millard was an early conservationist.
