"Your expenses both in town and country must certainly be considerable, but your income is a large one."
"Not so large, I dare say, as many people suppose. I do not mean to complain, however; it is undoubtedly a comfortable one, and I hope, will in time be better. The inclosure of Norland Common, now carrying on, is a most serious drain. And then I have made a little purchase within this half year -- East Kingham Farm, you must remember the place, where old Gibson used to live. The land was so very desirable for me in every respect, so immediately adjoining my own property, that I felt it my duty to buy it. I could not have answered it to my conscience to let it fall into any other hands. A man must pay for his convenience, and it has cost me a vast deal of money." (33.17)
