XIX. A CLEAN TONGUE. One of the first things the doctor does when he comes to see you, is to ask to look at your tongue, and one glance will tell him how much difficulty he has to contend with. If the tongue is foul, he knows that there is inward mischief, and he must lose no time in cleansing that of which the tongue is but an indicator. As we pass along our streets our ears are assailed with language of the most horrid description. If one needed any information as to the state of public morals, the foul-mouthed men and boys, aye, and we regret to say, too often, women and girls, would tell of the state of heart into which many thousands of our country people have been corrupted. And in many cases, this has become habitual, and what might be termed natural. Can nothing be done? Is the name of the Divine Being and that of our Saviour to be profaned constantly without any check? If so, it will grow worse and worse, until we may expect national sin to bring down national punishment, and we shall have to say, "Because of swearing the land mourneth." Those who have charge of the education of our children might help, by constantly speaking against bad language, and by punishing those who continue to offend. Parents, also, should check the slightest tendency in this direction. We have heard of a good woman, who, overhearing one of her boys using what she called "dirty words," took him to the sink, and washed out his mouth, not sparing the soap! Sometimes when we have heard men defiling their tongues with filthy talk, we have wished their mothers had served them the same. Nor is this offence against God and good taste always confined to the ignorant. There are those who have been well taught--men of ability, and some who make a profession of religion, who indulge in unseemly language, and delight in stories which are termed "smutty." We know how farmers dislike the "smut" in their wheat, how an otherwise good crop will be lowered in value, because the black grain will, when ground, darken the flour. Is it not so with these men of unclean lips? The filthy allusions and improper stories which pollute their conversation make their life infectious, and their companionship dangerous. Let us reprove them, or at least avoid them, as we would the plague. If we would keep a clean tongue, we must pray "Create in me a clean heart, O God!" This can be done, and the Lord, who has told us that He will not admit into His heaven that which worketh abomination, will gladly cleanse the thoughts of our hearts by the inspiration of His holy Spirit, then shall our tongue glorify Him continually.
