loam soil and by the post-oak association on poorly drained 

 shallow light gray silt loam having a light clay subsoil. The 

 forests of the northern Upland type are similar to the oak-hickory 

 type of the southern region but are characterized by an increase 

 in proportion of Basswood, Black Walnut and Sugar Maple. As 

 the extreme North is reached, the presence of Aspen, Black Birch, 

 Paper Birch and the sporadic occurrence of White Pine mark the 

 overlapping of the more northern tree associations. 



The present forest area of Illinois is estimated at two million 

 acres, or 5^% of the total land area. 



The considerations outlined above occupy approximately one- 

 half of the bulletin, the remaining half being concerned with such 

 subjects as ownership and taxation, timber industries and forest 

 management. We find that 115 million feet, exclusive of fuel, 

 post and ties, were cut in the State in 1909. 



It is unfortunate that a deficiency of funds did not allow the 

 publication of the map of forest types which was submitted by 

 the authors but not published.

The Blister Rust of White Pine. By Perley Spaulding. Bulle-

The issuing at this time of an exhaustive bulletin on the "blister 

 rust of the white pine" seems to be timely, for legislation aided 

 by the intelligent co-operation of importers of pine seedlings, 

 promises to prevent this pest, which has made such serious 

 ravages in Europe, from getting a foothold in America. The 

 fungus itself, is probably native to Eurasia, where it has been 

 long known. It passes its life history on two hosts, the aecidial 

 stage on some few species of pines (possibly originally on Pinus 

 cembra only) and the uredo — and teleuto — stages or various 

 species of currents and gooseberries (26 species of Ribes in all, 

 and none is known to be immune). The attention of Europeans 

 was first seriously directed to this disease by the damage wrought 

 to white pine, which has been so great in many places as to 

 actually interfere with its successful culture. The blister rust 

 fungus is essentially a bark disease of seedling pines and young 

 branches of older trees. It reveals its presence by swellings of
