you had better have another piece and save it,” and the weighing after dinner is a delightful operation. The power of judging of weight is worth cultivating. We heard the other day of a gentleman who was required at a bazaar to guess the weight of a monster cake; he said it weighed twenty-eight pounds fourteen ounces, and it did, exactly. _Cæteris paribus_, one has a greater respect for the man who made this accurate judgment than for the well-intentioned but vague person, who suggested that the cake might weigh ten pounds. Letters, book parcels, an apple, an orange, a vegetable marrow, fifty things in the course of the day give opportunities for this kind of object teaching, _i.e._, the power of forming accurate judgments as to the relative and absolute weight of objects by their resistance, which is perceived by our sense of touch, though opposed to our muscular force. By degrees the children are trained to perceive that the relative weights of objects depend upon their relative density, and are introduced to the fact that we have a standard of weight. In the same way children should be taught to measure objects by the eye. How high is that candlestick? How long and broad that picture-frame? and so on--verifying their statements. What is the circumference of that bowl? of the clock-face? of that flower-bed? How tall is so-and-so, and so-and-so? How many hands high are the horses of their acquaintance? Divide a slip of wood, a sheet of paper into halves, thirds, quarters by the eye; lay a walking-stick at right angles with another; detect when a picture, curtain, &c., hangs out of the perpendicular. This sort of practice will secure for children what is called a correct or true eye. A quick and true ear is another possession that does not come by Nature, or anyway, if it does, it is too often lost. How many sounds can you distinguish in a sudden silence out of doors? Let these be named in order from the less to the more acute. Let the notes of the birds be distinguished, both call-notes and song-notes; the four or five distinct sounds to be heard in the flow of a brook. Cultivate accuracy in distinguishing footfalls and voices; in discerning, with their eyes shut, the direction from which a sound proceeds, in which footsteps are moving. Distinguish passing vehicles by their sounds; as lorry, brougham, dog-cart. Music is, no doubt, the instrument _par excellence_ for this kind of ear culture. Mrs. Curwen’s “Child Pianist” puts carefully graduated means for this kind of culture into the hands of parents; and, if a child never become a performer, to have acquired a cultivated and correct ear is no small part of a musical education.
