The Division of Forestry Extension, organized in the r5ureau of 



Forestry on July i, to supersede the Section of Tree Planting, is to have 

 charge of all work that deals with the creation of forests .where at present 

 there are none. Field parties are' now at work in New Hampshire, Massa- 

 chusetts, New Jersey, Nebraska, Oklahoma, Arizona, Washington, and Ore- 

 gon. In connection with the system of cooperation with private land 

 owners in planting the Bureau of Forestry at the beginning of the present 

 field season had arranged 224 planting plans in 172 localities of twenty-nine 

 different states. The majority of these plans are for woodlots of individual 

 land owners, but in some cases plans are being made for corporations, cities, 

 and even states. The bureau has also established nurseries in the two forest 



r 



reserves recently established in the sand-hill region of Nebraska. The prin- 

 cipal species used at first will be jack pine, western yellow pine, white fir, T 



and Colorado blue spruce. The bureau has also recently taken up a study 

 of the tendencies of natural forests to extend over land devoid of forest 

 growth. Field parties are now investigating the reproduction of white pine 

 on pastures and abandoned lands in Massachusetts and New Hampshire ; 

 another field party is studying the san^^e problem in Oklahoma in connection 

 with the hard wood growth which composes the timber belts of that region ; 

 and a similar study is being made of the Prescott reserve in Arizona. The 

 reclamation of shifting sand dunes has also been taken up as a problem by the 

 bureau. The regions most severely affected are the dune regions of the 

 Atlantic and Pacific coasts, the lake district region of Michigan, and the 

 Columbia river district of Washington and Oregon. Two field parties are at 

 work on this [)roblem, the one investigating the dune district along the Atlan- 

 tic coast and the other the Columbia river district.
