George Frisbie Whicher, The Cambridge History of American Literature (1917)
“ During the first decade of the nineteenth century nearly every literary device and favourite character in the long line of British essayists was reproduced in this country. Isaac Bickerstaff owned an American cousin in Launcelot Langstaff of Salmagundi, memories of I’Espion turc were evoked by Wirt’s Letters of a British Spy, and Goldsmith’s Lien Chi Altangi dropped a small corner of his mantle on Irving’s Mustapha Ruba-Dub Kheli Khan and S. L. Knapp’s Shahcoolen. ”
