The habit of seeing whatever comes within the range of vision is a good
one and should be cultivated by the teacher. A love of flowers—a
refining emotion—will usually follow persistent attention to them. For
this reason it is well to acquaint children with their names, usual
location, change through culture, etc. Much can also be learned from
talking often about rock formations, leaves, etc. A teacher who cares to
do so will find a way to make such collections instructive, and yet keep
the discussion of them as well as the objects themselves in the proper
place.
