No young child, as a rule, can live, or, if he live, can be healthy, unless milk is the staple article of his diet. There is no substitute for milk. To prove the fattening and strengthening qualities of milk, look only at a young calf who lives on milk, and on milk alone! He is a Samson in strength, and is as fat as butter; and all young things are fat if they are in health!
Milk contains every ingredient to build up the body, which is more than can be said of any other known substance. A child may live entirely, and become both healthy and strong, on milk, and on milk alone, as it contains every constituent of the human body. A child cannot "live by bread alone," but he might on milk alone! Milk is animal and vegetable—it is meat and bread—it is a fluid, but as soon as it reaches the stomach it becomes a solid—solid food; it is the most important and valuable article of diet for a child in existence. It is a glorious food for the young, and must never, in any case, be dispensed with. How is milk, in the making of cheese, converted into curds? By rennet. What is rennet? The juice of a calf's maw or stomach. The moment the milk enters the human maw or stomach, the juice of the stomach converts it into curds—into solid food, just as readily as when it enters a calf's maw or stomach, and much more readily than by rennet, as the fresh juice is stronger than the stale. An ignorant mother often complains that because, when her child is sick, the milk curdles, that it is a proof that it does not agree with him! If, at those times, it did not curdle, it would, indeed, prove that his stomach was in a wretchedly weak state; she would, then, have abundant cause to be anxious. "Considering that milk contains in itself most of the constituents of a perfect diet, and is capable of maintaining life in infancy without the aid of any other substance, it is marvelous that the consumption of it is practically limited to so small a
