;6 REPORT OF THE FOREST COMMISSION. 



than chestnut, notwithstanding many published statements to the 

 contrary. 



Chestnut wood from trees killed by the blight is as sound and 

 good for ordinary purposes as the wood of trees felled while in 

 health. It is important to see that all lumber or cordwood shipped 

 out of the State, or into the southern counties, is completely barked 

 since it has been learned that the disease may live in unbarked logs 

 or wood for six months or more. Markets for chestnut lumber are 

 still good, though it must be borne in mind that the wood from one 

 or two isolated trees is less valuable than where a large quantity 

 is offered. 



ELM LEAF BEETLE. 



The ravages of this pest have been notably less than for several 

 years past. This is accounted for in part by a much more general 

 resort to spraying and in part by the establishment of a parasitic 

 enemy. True, many trees have died ; they were invariably those 

 that have been neglected. We may be so fortunate as to find this 

 pest retreating as it did a dozen years ago, but the time to relax 

 vigilance has not come. No elm tree need die of the leaf beetle ; 

 timely and careful spraying with arsenate of lead is an infallible 

 remedy. The effect of this treatment can be seen almost anywhere 

 in North Jersey where sprayed trees in perfect health stand beside 

 those dead and dying which have not been sprayed. Specific direc- 

 tions for spraying will be given by the Forest Commission, or by 

 the State Entomologist, though tree owners are recommended to 

 turn first to their local Shade Tree Commision. Apart from other 

 advantages a Shade Tree Commission can have such work done 

 much cheaper than individuals. It may cost anywhere from $5 to 

 $20 to spray a single tree ; if the owners of 50 or more trees unite 

 the cost may be $2 or less. 



BROWN-TAIL MOTH AND GYPSY MOTH. 



Neither of these most dangerous insects has been established in 

 the State, and the likelihood that either will be is greatly lessened 

 by the passage of the National quarantine law referred to above. 

 Under it the Secretary of Agriculture has prohibited the shipment 

 from the infested territory of plants, lumber and anything that may 

 carry the pests to new territory. New Jersey is fortunate in having
