wood and of chestnut tan bark. An inspection of local conditions 
will readily determine whether the danger from these sources is 
sufficiently great to warrant the business inconvenience which would 
be caused by the quarantine of any or all chestnut products. 
Program for the second year—The work for the second year will 
consist mostly of reinspection of the advance spots where the bark 
disease has been eradicated the oe year and of general scouting 
to locate new spots. If the work of the first year has been thoroughly 
done and there has been time to complete the elimination of all spots 
located, only scattering infections may be expected. From this time 
on the persons in charge of scouting will have the bulk of work and 
responsibility. 
THE EXAMPLE OF PENNSYLVANIA. 
Pennsylvania enjoys the distinction of being the first and so far the 
only State to undertake in any way the control of the chestnut-bark 
disease. In the summer of 1910 the Main Line Citizens’ Associa- 
tion—an organization of citizens residing along the main line of the 
Pennsylvania Railroad near Philadelphia—appointed a committee of 
seven, under the chairmanship of Mr. Harold Peirce, to determine the 
status of the disease in that locality and to see what could be done 
toward controlling it. An extensive local survey of the disease was 
made under the direction of Mr. I. C. Williams, deputy State forest 
commissioner. The committee soon became convinced that the prob- 
lem was of State and even national importance, and could only be 
solved by legislation and by the broadest cooperation. Accordingl 
they devoted their energies to securing the passage by the Peanagl 
vania Legislature of the following bill, which has now become a law. 
This law is almost unique in conservational legislation, and on ac- 
count of its important bearing as precedent for similar laws in other 
States it is here reproduced in full.
