Most of the nail is fast to the finger, but at the outer edge there is a little space =between= the nail and the finger, and if we are not careful this little space gets filled with dirt, and then the nail has a black band across the top, which looks very ugly. When the nails are long, the band is wider, and, although the dirt is =under= the nail, it shows on the outside, because the nail is transparent, that is, it can be seen through.

Do you like to have your hands clean? Then there must be no black bands to disfigure the pretty, shining nails; our hands cannot be called clean if there is a little arch of dirt at the tip of each finger. Ask mother to cut the nails when they get too long, then you can keep them clean more easily.

Men who do work that soils their hands very much like the chimney-sweep (Story Lesson 62) cannot possibly keep their nails clean, but children can.

Story Lessons of Character Building (Morals) and Manners — Part 40

There was once a little boy who had the funniest finger-tips I ever saw. The nails were so short that there was not the tiniest space between the outer edge and the fleshy part, and so the tip of each finger had grown out like a little round cushion, not at all pretty to look at. If the little boy saw any one noticing his hands, he would hide them away, lest he should be asked what it was that caused the finger-tips to look so funny. I wonder if =you= can guess the reason? It was because the boy bit his nails. What a horrid thing to do! Was it not? And how do you think his mother cured him? She dipped the tips of his fingers in tincture of bitter aloes, so that when he put them in his mouth he might get the bitter taste, and leave off biting them.

I once heard a gentleman say that =he= thought it was very rude to put a pencil or anything near the mouth, so what would he think of a child who put his =fingers= in his mouth, and bit his nails? Baby may suck her little thumb sometimes, perhaps, because she does not know better, but sensible children will remember that it is rude to put fingers in mouth.

Keep your Nails Clean. Do not put Fingers in Mouth.

Can you think of anything else that should be kept clean besides the nails? In your mouth are two rows of beautiful little, white teeth. At least they =ought= to be white, but if we do not keep them clean, they often get discoloured and begin to decay and give us pain.
