740 EXPERIMENT STATION RECORD. 



examiuation of forest conditions in tUe natural forests and forest plantations in 

 tlie Wallionding ^'alley, and parts of central and sontlieru Ohio. 



The territory covered wholly or in part includes i9 counties. Consideration 

 is given to the geology of the various sections examined, as well as to the 

 constitution and nature of the existing stands. The present condition of several 

 artificial forest plantations of various ages is discussed, special attention being 

 given to catalpa plantations, this species being the one most planted on account 

 of its rapid grovi^th and quick availability for posts and pole material, and for 

 windbreaks. 



Out of 645,270 trees distributed by the station since 1904, 426,812 were 

 catalpa. During the past summer data were collected on the rate of growth 

 of a number of catalpa groves throughout the area surveyed. Considerable 

 variation was found in groves of the same age growing in different situations. 

 The effect of various soils, methods of pruning, different planting distances, and 

 thinning as influencing the i-ate of growth is discussed. Briefer notes are also 

 given on other important species examined. 



The reclam^ation and reforestation of the high moors in Belgium, N. I. 

 Crahay (Bui. Soc. Forest. FraiicJie-Comte ct Belfort, 10 il<)09), No. 3, pp. 

 21.'t-221). — A summarized account of the work being undertaken by the Bel- 

 gian forestry department in reforesting the high moor or peat lands. 



On the reforestation of culm piles and abandoned quarries, G. Leonard 

 (Ann. Gcinbloiix, 10 (1909), Xo. 10, pp. 558-510, pis. 3).— A thesis in which the 

 author shows the possibilities of reforesting culm piles from coa4 mines and 

 abandoned quarries, by giving an account of work which has been accomplished 

 along this line in different sections of France, including the species of plants 

 and trees best suited for these situations. 



On the use of chemical fertilizers in forest plantations, A. Mathey (Bui. 

 Soc. Forest. Franchc-Comte ct BcJfort, 10 (1909), No. 3, pp. 3J,-'i-3Ji6, fig. 1).— 

 Basic slag used alone and in conjunction with kainit, 2 : 1, has been tested for 

 several years as a fertilizer in plantations of Austrian pine, Norway spruce, and 

 of various hardwoods in the calcareous waste lands of the Burgundisin hills. 



The general result has been a considei'able increase in growth. The effect 

 was immediate with the spruces and the majority of the hardwoods, and was 

 noticeable when the plants were 2 years old in the case of the pines. The maxi- 

 mum expense per tree is given as 1 centime (0.2 ct. ), 40 to 100 gm. of the mix- 

 ture being used per tree. In one case fertilized 2-year-old black pines made 

 as much growth as unfertilized 7-year-old i)lants. 



The German forest, M. Buesgen (Dcr Deutsche WaUI. Lcipsic [1909], pp. 

 176, pis. 2, figs. 44) • — A book popular in scope containing considerable informa- 

 tion on the forests of Germany relative to their history, constitution, . and 

 forest operations and industries. 



A statistical review of the forest administration of the Grand-Duchy of 

 Baden for the year 1907 (Statis. Nachw. Forstverw. Baden, 30 (1907), pp. 

 ■''iJi+XX+139, pis. 13, dgms. 11). — Part 1 of this review is a general considera- 

 tion of the forest conditions in Baden with special reference to forestal de- 

 velopment. The data showing forest development along various lines are por- 

 trayed in a series of colored charts. 



Part 2 consists of a statistical review of the government forest administra- 

 lion relative to forest areas, planting and cutting operations, iind yields and 

 revenues from various forest proilucts, together with comparative data on net 

 revenues for the past 40 years. 



In part 3 statistical data for 1007 are given for the community and coopera- 

 tive forests.
