On recently cut-over areas which have not been burned tree plant- 

 ing is seldom necessary, for the more valuable species will usually 

 come in without artificial aid. Cut-over lands which have recently 

 been burned, so that the growth of worthless species is checked, offer 

 exceptionally good opportunities for planting. Lands on which 

 sprout or seedling growth is scarce or poorly distributed may be 

 reforested by planting the bare areas. 



WORN-OUT AGRICULTURAL LAND. 



There is a large amount of land, particularly in New England and 

 Michigan, which was cleared for farming, but which afterwards 

 deteriorated in value, principally through loss of fertility. Through- 

 out Massachusetts, Connecticut, and New Hampshire, many of these 

 abandoned farms and old pastures grew up to white pine. This crop 

 is rapidly being removed, and because no seed trees are being left, 

 little natural reproduction is taking place. Such lands, because of 

 their nearness to market and their freedom from brush cover, offer 

 exceptionally fine opportunities for forest planting. 



SAND DUNES AND BARRENS. 



There are large areas of barren sand plains, notably in Connecticut, 

 Rhode Island, New Hampshire, Massachusetts, New Jersey, and 

 Michigan, which can not be tilled and which are a source of expense 

 to their owners. These sandy lands are suited to the requirements 

 of several hardy conifers, and, in many instances, will even support 

 a good growth of white pine. As in the case of sand dunes, the 

 problem is not one of purely commercial planting, but of preventing 

 drifting sand from encroaching on valuable property. 



WATERSHED PROTECTION. 



Many large towns and cities store their water supply in lakes or 

 reservoirs. Streams from bare watersheds flow in muddy torrents. 

 Floods occur in the spring, and the water soon becomes exhausted in 

 time of drought. As a result, there is likely to follow not only a 

 water famine, but also an epidemic of disease, the germs of which 

 find perfect conditions for development in the stagnant pools that are 

 left by the shrunken streams. After the first heavy rain, these dis- 

 ease germs are washed into the reservoir below, contaminating the 

 entire water supply. Water from slopes covered by forest is pure. 

 Forests regulate the flow, prevent erosion and turbidity, and make 

 waste areas beautiful and productive. Wherever natural reproduc- 

 tion can not be depended upon to cover the pastures and bare lands
