In 1772 Shore went to Rajshahi as first assistant to the resident of the province. In the following year he acted temporarily as Persian translator and secretary to the board at Murshidabad. In June 1775 he was appointed a member of the revenue council at Calcutta. He continued to hold that post until the dissolution of the council at the close of 1780. Though he revised one of the bitter philippics launched by Philip Francis against Warren Hastings, and is said to have written one of the memorials against the supreme court and Sir Elijah Impey, he was appointed by the governor-general to a seat in the committee of revenue at Calcutta, which took the place of the provincial council.
