manner of things--reels, rings, boxes, tins, that is to say a variety of
surfaces--is offered to him, to his great delight and advantage. And
lest he should not get the full benefit of such privilege he carries
everything to his mouth, where the sense of touch is very keen."[17]

Among the treasures kept for special occasions there may be pipes for
soap-bubbles, a prism of some kind with which to make rainbows, a tiny
mirror to make "light-birds" on the wall and ceiling, and a magnet with
the time-honoured ducks and fish, if these are still to be bought, along
with other articles, delicately made or coloured, which require care.

Pictures and picture-books should also be considered; some being in
constant use, some only brought out occasionally. For the very smallest
children some may be rag books, but always children should be taught to
treat books carefully. The pictures on the walls ought to be changed,
sometimes with the children's help, sometimes as a surprise and
discovery. For that purpose it is convenient to have series of pictures
in frames with movable backs, but brown-paper frames will do quite well.
The pictures belonging to the stories which have been told to the
children ought to have a prominent place, and if the little ones desire
to have one retold they will ask for it.

It is of course not at all either necessary or even desirable for any
one school to have everything, and children should not have too much
within the range of their attention at one time. Individual teachers
will make their own selections, but in all cases there must be
sufficient variety of material for each child to carry out his natural
desire for observation, experiment and construction.
