luncheon will have arrived. This is a very necessary meal between an early breakfast and a late dinner, as a healthy person, with good exercise, should have a fresh supply of food once in four hours. It should be a light meal; but its solidity must, of course, be, in some degree, proportionate to the time it is intended to enable you to wait for your dinner, and the amount of exercise you take in the mean time. At this time, also, the servants' dinner will be served. In those establishments where an early dinner is served, that will, of course, take the place of the luncheon. In many houses, where a nursery dinner is provided for the children and about one o'clock, the mistress and the elder portion of the family make their luncheon at the same time from the same joint, or whatever may be provided. A mistress will arrange, according to circumstances, the serving of the meal; but the more usual plan is for the lady of the house to have the joint brought to her table, and afterwards carried to the nursery.
