"The rector of a parish as much to do.--In the first place, he must make such an agreement for tythes as may be beneficial to himself and not offensive to his patron. He must write his own sermons; and the time that remains will not be too much for his parish duties, and the care and improvement of his dwelling, which he cannot be excused from making as comfortable as possible. And I do not think it of light importance that he should have attentive and conciliatory manners towards everybody, especially towards those to whom he owes his preferment. I cannot acquit him of that duty; nor could I think well of the man who should omit an occasion of testifying his respect towards anybody connected with the family."(Chapter 18)

If I read this correctly, a minister's duties are, first maximizing his income without shocking his patron, writing sermons, parish duties, fixing up his house & garden, and toadying up not only to the patron but also to all their relations.
