After several years teaching on the southern coast of Western Australia, Erickson requested and received a transfer to the school at Bolgart north of Toodyay in 1934. It was here that she regularly passed by "Hawthornden", the historic house of pioneer settler, botanist and naturalist James Drummond. Later she would write a detailed family history of the Drummond family, in "The Drummonds of Hawthornden", as well as histories of the surrounding districts in "The Victoria Plains" and "Old Toodyay and Newcastle". Another interest that she followed in Bolgart was bees and wasps, which she studied with the apiologist Tarlton Rayment.
