and the same State. The subjoined data will show the variation 

 within the State of Wiirttemberg : 



150 Executive charges with- a total area of 925,000 acres or an average of 

 6,175 acres to each executive charge. 



From the above outline one can see that there are in Wiirttem- 

 berg 30 executive charges, i. e., one-fifth of the total number, 

 that have less than 5,000 acres, and 80 or over one-half of 

 the total number, that have less than 6,250 acres. These figures 

 are of a comparative value and will act as a guide for those who 

 are concerned with the allotment of areas to forests. In Ger- 

 many a single executive charge may comprise State, Municipal 

 and Communal forests which make the forester's work more 

 difficult. 



The subjoined data of 10 of the 49 State Forests of Penn- 

 sylvania will show their wide variation in size :

One cannot help but realize that the factors which influence 

 the size of the area under the charge of one executive officer 

 are operative in all countries. The degree of their importance 

 varies, however, within the same country, the same State, and 

 often the same local region. That the size of State Forests varies 

 at the present time can be seen in the above tabulation of the State 

 Forests of Pennsylvania and that they will ever continue to vary 

 can be inferred from the tabulation given above of the forests 

 of Wiirttemberg, where forestry has been in practice for more
