Little Threads: or, Tangle Thread, Silver Thread, and Golden Thread by Elizabeth Prentiss.

The aim of Little Threads is happily indicated in its closing sentences: If you find that you like to have your own way a good deal better than you like your mamma to have hers; if you pout and cry when you can not do as you please; if you never own that you are in the wrong, and are sorry for it; never, in short, try with all your might to be docile and gentle, then your name is Tangle Thread, and you may depend you cost your mamma many sorrowful hours and many tears. And the best thing you can do is to go away by yourself and pray to Jesus to make you see how naughty you are, and to make you humble and sorry. Then the old and soiled thread that can be seen in your mother's life will disappear, and in its place there will come first a silver, and by and by, with time and patience, and God's loving help, a sparkling and beautiful golden one. do you know of anything in this world you should rather be than Somebody's Golden Thread?—especially the Golden Thread of your dear mamma, who has loved you so many years, who has prayed for you so many years, and who longs so to see yon gentle and docile like Him of whom it was said: "Behold the Lamb of God!"

Little Threads is based upon a very keen observation of both the dark and the bright side of childhood. The allegory, in which its lessons are wrought, is, perhaps, less simple and attractive than that of Little Susy's Six Teachers, or that of Little Susy's Little Servants; but the lessons themselves are full of the sweetest wisdom, pathos, and beauty.—The Life and Letters of Elizabeth Prentiss (1882).
