In August, 1837, he was appointed city
coroner. He served as the third interim part-time
Protector of Aborigines from 1837 until 1839, replacing Captain
Walter Bromley, who had been dismissed after criticism from
The Register and was afterwards found drowned in the
River Torrens. :"Unlike his successor and the German Missionaries, Wyatt did not live at
Piltawodli. According to Foster (1990b: 39) he was "criticised for not 'going among' the Aborigines and for failing to provide information to the public about their culture." Nonetheless, Wyatt does provide valuable, though sometimes unreliable, information on the language of the
Kaurna people. After the German mission sources, it remains the next most important source and includes a sizable number of terms not recorded elsewhere. :A manuscript copy of Wyatt's wordlist,
Vocabulary of the Adelaide Dialect (Wyatt, 1840)14 in the Library of Sir
George Grey in the
South African Public Library,
Cape Town, contains only 67 words, though this is unlikely to represent the extent of Wyatt's knowledge of Kaurna at that time. A more comprehensive paper published later lists approximately 900 Kaurna and
Ramindjeri words. The cover page notes that the material was "principally extracted from his official reports" most of which would have been written when Wyatt served as Protector from 1837 to 1839. Assuming Wyatt's (1840) wordlist in the Grey collection is complete, presumably Wyatt went through his papers and extracted words he had recorded in the early days of the colony. The
University of Adelaide Library copy, donated by the author, contains three corrections in Wyatt's own hand, where
n has been typed instead of
u. This wordlist was also published in
J. D. Woods ed. (1879) without correction of the three typographical errors. Wyatt identifies certain vocabulary items with a subscript e or r as
Encounter Bay or
Rapid Bay words respectively. In 1923, Parkhouse republished Wyatt's paper in three separate wordlists designating them 'Adelaide', 'Encounter Bay', and 'Rapid Bay' with changed spellings, substituting
u for Wyatt's
oo." The South Australian Colonial Railway Company was one of three public companies contending to build a railway between Adelaide and
Port Adelaide; the others being the
South Australian Railway Company and Adelaide City and Port Railway Company. ==Later life, death and legacy==
