the nurseryman is crooked or whether the people who accuse him are trying to get 
something for nothing when they say unfair dealings. But if any state official will 
report to our secretary any nurseryman who ships say peach with nematode roots 
and will not adjust the matter satisfactorily to all concerned, the Association will try 
to see that both parties have a satisfactory adjustment. 
Cooperation is the order of the day and we want to help you. 
Teach your inspectors to be a help in place of a scare. A few years ago the nursery¬ 
men growing fruit trees were in the clutches of an epidemic “the jumps” on receipt 
of a postal saying the inspector would arrive on a given date. They should look for 
seedlings as well as scale, and give the nurserymen helpful criticism, in order that they 
may improve their methods. 
THE GREEN JAPANESE BEETLE QUARANTINE 1 
By C. H. Hadley, Riverton , N. J. 
The primary purpose of any insect quarantine is the prevention of 
its further spread, but before any quarantine can be imposed, a thor¬ 
ough study of the insect in question is of course necessary, with par¬ 
ticular reference to the conditions which may cause, aid, or restrict, 
directly or indirectly, distribution and spread of the insect. Since a 
discussion of the green Japanese beetle problem as a whole has already 
been given at these meetings, it is only necessary here to give a brief 
statement of the conditions which necessitated the placing of this 
quarantine. 
It is known that the green Japanese beetle (Popillia japonica Newm.) 
was accidentally imported into Burlington County, New Jersey, from 
Japan sometime previous to 1916, probably as a grub in the soil about 
the roots of perennial plants. It was discovered during the month of 
August, 1916, by inspectors of the New Jersey State Department of 
Agriculture. Observations during the seasons of 1917 and 1918 showed 
that the insect was capable of reproducing at an amazing rate, and 
unless soon checked would, undoubtedly, develop into a pest of very 
considerable importance. It was further ascertained that the danger 
of the insect being carried from the infested territory on farm produce, 
especially green or sweet corn, was very great. Accordingly after 
necessary public hearings were held, quarantine order number 35, 
restricting the movement of green, sweet or sugar corn interstate from 
the infested districts, was published by the Secretary of Agriculture, 
to be effective June 1, 1919. This quarantine was shortly after sup¬ 
plemented by a similar measure, promulgated by the Secretary of 
Agriculture of the state of New Jersey, regulating the intra-state 
movement of green or sweet corn from the infested territory. 
The territory designated as the area under quarantine comprised the 
townships of Delran, Cinnaminson and Chester, all in Burlington
