Council of Heads of Australasian Herbaria
A migrant from Tipperary, was a shire engineer at Nhill and Dimboola from 1875 until after the 1914-18 War and he sent numerous exsiccatae to Mueller from the Little Desert and north ern fringes of the Gram pians. D'Alton published "Notes on the Plants Indi- genous to the North-West Portion of the Colony of Victoria " in 1898 (Proc. Aust. Assn. Adv. Sci VII) p. 455), and a comprehen sive "Botany of the Little Desert" (Vic. Nat. Aug. 1913) but, strangely, he makes no mention whatever of Reader's outstanding achievements in the same area. During his retirement in Melbourne, he wrote of his rich experiences in the Australasian.
