The following concerning some causes of heart disease, and the evils caused by the use of tobacco, we clip from the N. Y. Tribune. "There is an increase of heart trouble, as there always would be in feverish and hurried lives. Many lives are intense enough to strain the whole human system, and increase and hurry the circulation and finally weaken it. A prominent English physician has written his experience in the matter of athletic exercises. Young men, boys who are not fully developed, strain their young muscles, hurry their breathing and circulation, whether by athletic games or rowing. Of those who consulted him, he found hardly one who had a sound heart. The heart had been overworked, had been compelled to pump the blood faster than it could bear, and its power as a heart was impaired for life. It was older than the rest of the body. All excessive muscular exertion makes mischief with young people, before the frame is hardened and compacted by time. The effects may not appear at once, but will remain in the fact of lessened powers, and premature age - or death. The growing use of what are called nervines or stimulants, will increase the tendency to heart trouble. Hurried circulation makes the heart work the harder and wears out the poor pump earlier.

Aside from the medicines, which, when taken habitually are no more medicines (since those are understood to be only remedial measures for disease), the growing use of tobacco is a serious evil. If used at all freely, it most certainly shortens life; and when taken by the young (and boys who are scarcely more than infants are now seen with cigarettes), it prevents full development and dwarfs and twists the whole nervous system. In this weakness the heart shares, and many a weak and trembling heart, which finally stops for very weariness, owes its weakness to this powerful and deadly nervine. It does not kill at sight, but, none the less, it does harm. A monkey will eat tobacco with impunity, but it does not follow that human beings will bear it. And even men are careful about the juice or oil. "Keep thy heart with all diligence," may apply to physical no less than to moral well-being."
