Mastication, or chewing, is the first step in the process of digestion. When food is taken, it should be thoroughly masticated before it is suffered to pass into the stomach. Without chewing, the food is too coarse and gross for the stomach; and is unprepared for the action of the gastric juice. Besides this, the action of chewing causes the food to be mixed with the saliva; which is an important item in the preparation of it for the action of the stomach and its juice. The food should therefore be broker. up into a fine mass and well moistened with saliva. In order to accomplish this end, it is highly necessary that food should be taken with sufficient moderation to give time for the process of mastication and the discharge of saliva from the glands of the mouth. Eating fast, or even talking while chewing, besides its incongruity with politeness and good breeding, is directly at war with thorough mastication.

Many persons seem to think that hurrying their meals to save time is economy; their business drives them, and they drive their time of meals into the smallest possible compass. This is miserable economy; for when they hurry clown their food, half chewed and half moistened with saliva, it deranges the process of digestion throughout; and, as a consequence, the food not only sets bad on the stomach, and in time causes dyspepsia, but it fails to accomplish the sole object of taking it -- the nourishment of the body. In order to derive nourishment from food, it must be well digested; hence it must be well masticated. When, therefore, we hurry our eating, we hasten our steps on the wrong road. Time curtailed in eating, is worse than hiring money at three per cent. a month. If we cannot spare time to eat, we had better not eat at all. This idea cannot be too deeply impressed: thousands, by this kind of careless, reckless eating, have found themselves the victims of dyspepsia, and all its attendant train of evils. The digestive organs may bear the abuse awhile without giving many signs of trouble; but the penalty of that broken law must, sooner or later, come; and it may come in the form of a broken constitution.
