Demonstration techniques remain largely undeveloped despite low-cost possibilities

Evidence

I could go from here to a long list of excellent demonstrations that are actually being done either in National Park Service areas or by other interpretive agencies, but the point I wish to make is that we have by no means more than skimmed the surface of the possibilities in demonstration. That demonstrations will never be sufficiently numerous in any place of interpretation I sadly admit. No doubt local peculiarities often forbid them. It must be added, too, that lack of money and personnel have prevented, in the past, such desirable development of this fruitful educational device. Still, I am persuaded that in many areas much can be done with little, if imaginative and deliberate assessment of the possibilities is employed. — Freeman Tilden, Interpreting Our Heritage, 461
