I was reading the other day that the first great lesson for a _young man_ to learn, the first fact to realize, is that he is of some importance; that upon his wisdom, energy and faithfulness all else depends, and that the world cannot get along without him. Now if this is true of young men, I do not see why it is not equally true of young women. It is not after you have grown old that you will be of value to the world; it is now, in your young days, while you are laying the foundation of your character, that you are of great importance. We cannot say that the foundation is of no importance until the building is erected, for upon the right placing of the foundation depends the firmness and stability of the superstructure. Dr. Conwell, in his little book, "Manhood's Morning," estimates that there are twelve million young men in the United States between fourteen and twenty-eight years of age; that these twelve million young men represent latent physical force enough to dig the iron ore from the mines, manufacture it into wire, lay the foundation and construct completely the great Brooklyn Bridge in three hours; that they represent force enough, if rightly utilized, to dig the clay from the earth, manufacture the bricks and construct the great Chinese Wall in five days. If each one were to build himself a house twenty-five feet wide, these houses would line both sides of eight streets reaching across the continent from the Atlantic to the Pacific. For each one to be sick one day is equal to thirty thousand being sick an entire year. Now, if there are twelve million young men in the United States, we may estimate that there are an equal number of young women. Although we cannot calculate accurately the amount of physical force represented by these young women, there are some things we can tell. We know that for each one of these young women to be sick one day means thirty thousand sick one year. Just imagine the loss to the country, and the gain to posterity if it can be prevented!
