Our supplies of ash, black walnut and hickory, once abundant, are now seriously limited.
Formerly, these mixed forests covered vast stretches of country which today support only a scant crop of young trees which will not be ready for market for many years.

These second-growth stands will never approach in value or quality the original forests.

Over large areas, poplar, white birch, and Jack pine trees now predominate on lands which formerly bore dense stands of white pine.

In many places, scrubby underbrush and stunted trees occupy lands which heretofore have been heavy producers of marketable timber trees.
Generally speaking, farm lands should not be used for forestry purposes.

On the other hand, some forest lands can be profitably cleared and used for agriculture.
