Booth extensively traveled the country and the globe, with performances in Sacramento and San Francisco, California as well as a brief run of The Merchant of Venice in Sydney, Australia. By the time he traveled east in 1855. Booth had matured and gained confidence as an actor: "His style was inevitably moulded by that of his father and by the whole Kean tradition but it was marked by an intellectuality and a sustained power which the elder Booth never achieved. Not super-eminent as a comedian, in tragedy the younger Booth was soon to reach the level of Kean himself."
