Tuhia he haere tonu mo tenei irava - He rongonui a Gruelle mo ana peita whenua, me tana pukapuka, "Notes: Critical and Biographical: Collection of W. T. Walters" (1895). Ko nga mahi toi a Gruelle mai i te wa i noho ai ia ki Gloucester, Massachusetts, kei roto i ana mahi pai rawa atu, ina koa ko ana peita wai. I roto i ana peita tino rongonui ko te raupapa o nga tirohanga moana kei roto ko "Te Whakaaturanga o nga Taonga".

I tere te whiwhi a te Art Association o Indianapolis i te peita, a kei roto tonu i te kohinga o te Whare Taonga Toi o Indianapolis. I whakaatu noa a Gruelle i ana mahi i roto i nga whakaaturanga a motu, me te rua o nga mea whakahirahira. I whakaatuhia e ia i te Society of Western Artists whakaaturanga a-tau me te 1904 i te Louisiana Purchase Exhibition
i Saint Louis, i Misuri. I pai a Gruelle ki nga whakaaturanga takitahi i Indianapolis, Indiana, me New Canaan, Connecticut.
