The regard which he entertained for his master in the law is well shown by his conduct as the opposing advocate during the hearing on the Writs of Assistance, when Otis having resigned his post of Advocate-General of the Province in order to champion the people's cause, the vacancy was filled by the appointment of Gridley. Otis held the character and abilities of his former teacher in very high respect, and allowed this differential feeling to appear throughout the trial. "It was," says John Adams, who was present on this occasion, and from whom nearly all the details of the course of this affair are derived, "it was a moral spectacle more affecting to me than any I have ever seen upon the stage, to observe a pupil treating his master with all the deference, respect, esteem, and affection of a son to a father, and that without the least affectation; while he baffled and confounded all his authorities, confuted all his arguments, and reduced him to silence." Nor was a suitable return wanting on the part of Mr. Gridley, who "seemed to me to exult inwardly at the glory and triumph of his pupil." Though he made no pretensions to scholarship, some of his writings showed a cultivated taste and a love of literary pursuits, which were gratified so far as his numerous engagements in public service would permit. With a literary taste formed and matured by the study of Latin and Greek prosidy as constituted in the best models of antiquity, it is not surprising that his opinions on matters of criticism and scholarship were those of the Odd school, and that he decried all the forms of innovation in letters which had begun to show themselves in his day, and which he regarded as affectations. His constant advice to young people was if you want to read poetry, read Shakespeare, Milton, Dryden, and Pope; throw all the rest in the fire. And with the addition of but one or two names which have appeared since his time, such counsel is judicious advice even to-day.
