EXPERIMENT STATION BULLETINS. 481 



There is a law now before congress which prohibits transportation 

 companies, postmasters, etc., from receiving nursery stock of any kind 

 that is not accompanied by a certificate of inspection. 



DUTIES OF OWNERS OF LAND. 



Owners are required by law, in case they have peach trees diseased 

 with yellows and rosette, to forthwith destroy the trees and fruit, and 

 to cut off and destroy the portions of pear trees diseased with blight, and 

 black knot upon plum and cherry trees. 



When trees are infested with canker worms, San Jose" scale and other 

 injurious insects, or are infected with dangerous diseases, owners are 

 required by law to effectually spray the trees, or, if necessary, to destroy 

 them. Spraying, except for the canker worm, is prohibited while the 

 trees are in blossom. Under the spraying law such injurious diseases 

 and insects (aside from those mentioned above) would naturally be in- 

 cluded, as are not commonly distributed, or which if not destroyed are 

 likely to injure neighboring trees. 



In case notice is served on the owners, by the commissioners, or by the 

 State Inspector of Orchards or by his deputies, requiring the destruction 

 or the spraying of the trees, (unless they avail themselves of the right to 

 appeal as noted hereafter) they must comply with the requirements within 

 live days or they will be subject to fine or imprisonment. 



DUTIES OF TOWNSHIP OFFICERS. 



When any township board or city council are aware of the presence of 

 dangerous insects or diseases, within their jurisdiction, or when ten free- 

 holders petition for it, it is their duty to appoint three competent free- 

 holders as commissioners, who shall hold office during the pleasure of the 

 board and until their successors are appointed. If the township officers 

 neglect or refuse to make the appointment, they are subject to fine or 

 imprisonment or both. 



DUTIES OF THE COMMISSIONERS. 



The commissioners shall, within ten days after appointment, file their 

 acceptance with the city or township clerk, who shall be the clerk of the 

 board and keep a record of their proceedings. 



It is the duty of the commissioners, or any one of them, to examine any 

 trees supposed to be infected with dangerous diseases or insects, and if the 

 diseases or insects are found, they must put some mark upon the tree and 

 serve notice upon the owner to destroy the tree if it is infected with yel- 

 lows, or to cut off the diseased portions if it is black knot, pear blight, 

 etc., or to effectually spray the trees in case of dangerous insects, 

 within five days. When infected with San Jose" scale the commissioners 

 can, if deemed necessary, order the destruction of the trees. When the
