244 Forestry Quarterly 



A consideration of the teredo historically, anatomically and 

 economically with special reference to methods for the control 

 of its ravages. Includes an extensive bibliography. 



The teredo bores through wood by means of the shell valves on 

 its head. The abraded wood furnishes little, if any, nourishment 

 to the animal. The only woods considered fairly resistant natu- 

 rally to the attacks of the borer are jarrah, greenheart, and tur- 

 pentine wood (presumably Eucalyptus stuartiana) . 



Impregation with salt solutions, superficial coatings, etc., have 

 proved ineffectual or of only limited efficacy in protecting wood 

 from the teredo. The best results have been secured by impreg- 

 nating thoroughly seasoned wood with creosote containing at 

 least 6 to 10 per cent of tar acids, the absorption to be not less 

 than 150 liters per cubic meter (about 8 pounds per cubic foot) 

 of wood. S. J. R.
