Foresters are, generally, agreed that as much as 25 per cent.

of the forest land of every state should be publicly owned for producing large sized timber, requiring seventy-five to one hundred years to grow, and which the private owner would not be interested in producing.
National, state, or communal forests must supply it.

All of these combined comprise a very small part of the forests of most of the states, so that much larger areas must be acquired by the states and the national government to safeguard our future timber supplies.
Not less than thirty-two states are actually engaged in state forestry work.

Many of them have well-organized forestry departments, which, in states like New York and Pennsylvania, having large areas of state forests, are devoted largely to the care and protection of these lands.

In other states having no state forests, the work is largely educational in character.
The most notable progress in forestry has been made in fire protection.
