I would really like to slap Isabella when she receives news of what Mr Moreland is going to do for James.

Let's think about this practically. We don't know what Mr Moreland's income is, but he is described as having a 'considerable independence, besides two good livings'. Correct me if I'm wrong, but the considerable independence couldn't be that considerable given that he had to work as a clergyman to supplement it.

We learn that he is actually going to give one of his livings over to James, worth 400 pounds a year. Presumably the cheaper of the two livings was given over, but my guestimate is that would still be in the ball park of a quarter to a third of Mr Moreland's income! Plus an estate is still to come of at least 400 pounds a year. What a generous father! JA describes this as 'no trifling deduction from the family income, no niggardly assignment to one of ten children'. Which leads to another thing. How will the other 9 siblings fare given that so much of their father's income is tied up in one sibling?
