74 REPORT OF THE FOREST COMMISSION. 



to pay only the forester's actual expenses while away from Tren- 

 ton. His salary is paid by the State. Municipalities and* institu- 

 tions will pay nothing. No young trees or seeds are furnished by 

 the State. Special advice and assistance will be given any organ- 

 ized Shade Tree Commission without charge unless extended serv- 

 ice is desired. In that case a definite arrangement will be made. 



TREE PESTS. 



The number of tree enemies in no wise lessens. Chestnut blight, 

 elm leaf beetle, fake tree-doctors and their kind are still with us. 

 Nevertheless, our tree interests are better off in this respect than 

 they ever have been. The State Plant pathologist appointed last 

 year, Dr. Mel. T. Cook, has his office organized and already has 

 four assistants studying plant diseases and enforcing the laws re- 

 garding them. On October I a new State Entomologist, Dr. T. J. 

 Headlee, took up his duties as successor to the lamented Dr. John 

 B. Smith. Thus with active officials and adequate laws the State 

 is well provided to hold in check all diseases and insects dangerous 

 to plant life. With these officials the Forest Commission and its 

 foresters are working in complete harmony. 



Another factor of great importance is the passage by Congress 

 of a law, as recommended in our report for 1911, authorizing the 

 Secretary of Agriculture to restrict, or to prohibit, the importation 

 into the United States of diseased or insect-infested plants ; to pro- 

 hibit the importation of any or all plants from a country or district 

 known to harbor diseases or insects dangerous to plants, and to 

 control the movement of diseased or infested plants from one State 

 to another. New Jersey needed this law more than most States 

 because so many foreign plants are landed here. -Under it the 

 importation of White Pine from certain districts in Germany, 

 where the Blister Rust (See p. 77) is prevalent, is prohibited. 

 An embargo has been placed also on the shipment of Christmas 

 trees from sections of New England infested with brown-tail and 

 gypsy moths. 



The present situation with respect to the more serious tree pests 

 is as follows:
