Between 1886 and 1896 Mary Malone, a young Australian woman of Irish Catholic background, selected eighty‐two articles and fifty‐nine poems to preserve in an old school exercise book. This article argues that the clippings Mary assembled in her exercise book formed a narrative designed to secure a sense of social identity as the Australian colonies moved towards Federation in 1901. The exercise book reflects Mary's meditation on the stories of the colonial public sphere, a meditation that in turn faciliated her participation in community, work and as a citizen. Mary's exercise book reveals the mutual dependence of public and private realms of knowledge and experience, and the subjective assimilation of public discourse required to take a place in the social world.
