 improved highways. 



OILED ROADS. 



Some apprehension is abroad that the use of dust-reducing 

 preparations on stone roads will injure nearby trees. Ground 

 for this fear is given in reports from France that some loss has 

 been suffered where a roadbed had been treated with tar. The 

 evidence is not conclusive, however, and insofar as our terri- 

 tory is concerned there is no immediate danger. Nevertheless, 

 to forestall any possible trouble from the continued use of these 

 surfacings a series of experiments and tests is to be undertaken 

 with a view to determining the actual effect upon vegetation of 

 road-building methods and road materials. 



SHADE TREE BOOK. 



The Commission's publication, "The Planting and Care of 

 Shade Trees." See p. 42. apparently meets a real need. It is in 

 constant demand and though still available, it has been found 

 necessary to limit its distribution to citizens of the State. 



TREE PESTS. 



The open winter and wet early spring favored the development of 

 an unusual number of insect pests. Cottony maple scale, tulip 

 soft scale, and elm scale were prevalent on trees of those species. 

 Some damage was done, and in numerous cases it was necessary 

 to resort to treatment, but there is no reason to believe that 

 natural enemies will not soon restore the normal balance. The 

 State Entomologist and the State Plant Pathologist, either of 

 whom may be addressed at New Brunswick, are active in look- 

 ing after troubles in their particular lines and the State For- 

 ester is working in complete harmony with them. There is no 

 indication of any dangerous new pest attacking our trees and 

 forests. 



The Federal law under which the Secretary of Agriculture is 

 controlling the importation of, and the interstate traffic in, dis- 

 eased or insect infested plants is in full operation and is effec-
