The process of drying made it possible to preserve the products of our gardens and farms, and dried vegetables take up so little room and weigh so little that they can be carried across the ocean far more easily than fresh ones. In these fruits and vegetables mineral matter is found, especially lime and iron. These mineral sub- stances are necessary to all the processes going on in the body, and an important part of their work is help- ing to make bones and teeth. If you leave a bone in weak acid, such as vinegar, for a few days, the acid will eat most of the mineral matter out of it. The bone will look much the same, but if you take hold of it, you will find that it will bend almost like rubber and can actually be tied in a knot. ‘This shows how bones behave if they do not have enough lime to keep them stiff. Children’s bones have a hard time in one way. They have not nearly so much mineral matter as those of grown folk, and therefore they are far more likely to be bent out of shape. If a little child walks before the bones of his legs contain enough mineral matter to strengthen them so they will hold up the weight of his body, he may become bow-legged. In another way, the bones of children have a great advan- tage. They do not break easily, and if one does break, it will soon knit, or grow together again, while if an
