On the Saginaw Forest Farm, at Ann Arbor, Mich., the planting of 1-year-old 

 chestnut seedlings will be contrasted with the success of planting nuts in seed 

 spots. White pine and red oak plantations, 6 acres each, will be made to test 

 different spacings. sowing, fall and spring planting, the effect of planting on 

 plowed and nnplowed ground, and the effect of cultivation. These 6-acre blocks 

 will later be used as a basis for experiments in thinning. 



_ At Higgins Lake the Michigan forestry commission will test various methods 

 of nursery practice and planting. They will also record, for comparison, 

 the cost of planting several species, when planting crews are organized 

 differently and the trees planted in different ways. 



At Berea College, Kentucky, and at the Mississippi Agricultural Experiment 

 Station, the growing and planting of several species are being carried on to 

 determine the best methods of reforesting waste lands. Special attention will be 

 paid to the growing of hickory at these stations. 



At Saranac Inn, the New York forest, fish, and game commission is cooperat- 

 ing with the Service in studying the best methods of growing conifers for 

 planting in the East. One phase of this work is the trial of introduced species. 

 Small quantities of Seed of Pinus cembra, Picca ajanensis, P. obovata, Abies 

 siMrica, Larix dahurica, and other native Siberian trees will be sown this 

 spring.

The Fung-us Trametes pini 



Specimens of a fungus found by K. W. Woodward on living trees of western 

 white pine and western larch in the Lewis and Clark National Forest prove to 

 be Trametes pini. This fungus, which attacks nearly all the commercial coni- 

 fers of the United States and Europe, is more destructive to western white 

 pine than to larch, and is especially destructive to mature and overmature 

 timber. The spores enter most trees through wounds in the top, but in the 

 western white pine they enter near the base of the trunk. The fungus spreads
