The Prairie Farmer gives an in. teresting account of a visit to these forests, which occupy 520 acres. Five miles from this is the •forest planted by Douglas for Mr. Hunnewell, of Boston, who was formerly one of the managers of the railroad company. The trees were set 4 feet apart, like as in corn hills, 2,720 trees to the acre. They were set in 1877-8. There are now about 2,500 living trees to the acre. Catalpa and Ailanthus are the kinds. The cost of attention to bring a young tree to 4 feet high, is 2 cents. They are kept clean like corn till large enough to smother their own weeds. One man can work from four to seven acres a day. In three years the trees can take care of themselves. Four feet apart is of course too close for permanent timber, but thick planting is preferable because it makes straight trunks, and it is believed that the struggle for life will kill off the weakest as fast as it is desirable that the stronger trees should get more room. Some trees are already getting an advantage over the others. A thousand or twelve hundred trees to the acre will probably be the ultimate timber product. Eight-year-old Catalpas are now 20 to 25 feet high and from 4 to 6 inches in diameter.

Some White ash are smaller than the Ailanthus or Catalpa. A small planting of Osage orange is also making " a fair slow growth," but the tangle of dead limbs from close planting would probably make them dangerous spreaders of a grand blaze in case of fire.
