Read it through once

When first Mr. Bennet had married, economy was held to be perfectly useless; for, of course, they were to have a son. This son was to join in cutting off the entail, as soon as he should be of age, and the widow and younger children would by that means be provided for. Five daughters successively entered the world, but yet the son was to come; and Mrs. Bennet, for many years after Lydia’s birth, had been certain that he would. This event had at last been despaired of, but it was then too late to be saving. Mrs. Bennet had no turn for economy; and her husband’s love of independence had alone prevented their exceeding their income.
