102 THIRTEENTH ANNUAL REPORT OF THE 



most important of these are the hog, skunk, fox, weasel, mole, domestic 

 fowl, blackbird, crow, and a few parasitical insects. The skunk and mole 

 are of especial value because of the large numbers of the grubs which they 

 destroy. 



Proposed Methods of Prevention. 



During the spring and summer of 1908 it is proposed to pursue the 

 following methods in an attempt to prevent, so far as possible, any further 

 damage by the White grub. 



1. Three-fourths of the area of the Wawbeek nursery will be plowed 

 up in the spring of 1908 and new beds made, as the trees at present occupy- 

 ing this area will all be taken out and sent to the plantations. While this 

 is being done, a man will be detailed to watch for and destroy all the grubs 

 and beetles that may be turned up by the plow. 



2. As the adult insect is readily attracted to a bright light, a sufficient 

 number of ' trap lanterns " will be placed in and around the nursery. 

 These traps will be ordinary kerosene lanterns placed over large tin trays, 

 each containing kerosene to a depth of about half an inch. It is believed 

 that the majority of the beetles that may fly into the nursery or emerge 

 from the ground will be captured before they have had an opportunity 

 to lay their eggs. 



3. All the beds will be carefully watched throughout the season, and 

 wherever there is any indication of its presence the grub will be dug up and 

 destroyed.

State Forester. 



The foregoing report is inserted here as it describes in detail a new and 

 remarkable condition, and this discussion of the subject will undoubtedly 

 prove interesting to every forester who is concerned in the management of 

 a forest tree nursery.
