The use of tea and coffee by boys is also a practice which should be interdicted. All wise physicians forbid the use of these narcotic drinks, together with that of tobacco, and always with benefit to those who abstain. In France the government has made a law forbidding the use of tobacco by students in the public schools. In Germany a still more stringent law has been made, which forbids the use of tobacco by boys and young men. These laws have been made on account of the serious injury which was evidently resulting from the use of the filthy weed to both the health and the morals of the young men of those countries. There is certainly an equal need for such a law in this country. Closing Advice to Boys and Young Men.--One word more and we must close this chapter, which we hope has been read with care by those for whom it is especially written. Let every boy who peruses these pages remember that the facts here stated are true. Every word we have verified, and we have not written one-half that might be said upon this subject. Let the boy who is still pure, who has never defiled himself with vice, firmly resolve that with the help of God he will maintain a pure and virtuous character. It is much easier to preserve purity than to get free from the taint of sin after having been once defiled. Let the boy who has already fallen into evil ways, who has been taught the vile practice the consequences of which we have endeavored to describe, and who is already in the downward road,--let him resolve now to break the chain of sin, to reform at once, and to renounce his evil practice forever. The least hesitancy, the slightest dalliance with the demon vice, and the poor victim will be lost. Now, this moment, is the time to reform. Seek purity of mind and heart. Banish evil thoughts and shun evil companions; then with earnest prayer to God wage a determined battle for purity and chastity until the victory is wholly won. One of the greatest safeguards for a boy is implicit trust and confidence in his parents. Let him go to them with all his queries instead of to some older boyish friend. If all boys would do this, an immense amount of evil would be prevented. When tempted to sin, boys, think first of the vileness and wickedness of the act; think that God and pure angels behold every act, and even know every thought. Nothing is hid from their eyes. Think then of the awful results of this terrible sin, and fly from temptation as from a burning house. Send up a prayer to God to deliver you from temptation, and you will not fall. Every battle manfully and successfully fought will add new strength to your resolution and force to your character. Gaining such victories from day to day you will grow up to be a pure, noble, useful man, the grandest work of God, and will live a happy, virtuous life yourself, and add to the happiness of those around you.
