PREVENTING THE SPREAD OF THE INSECT. 
THE FEDERAL QUARANTINE AGAINST THE CORN BORER. 
The importation from foreign territory of plants likely to contain 
the European corn borer is regulated or forbidden by the terms of 
the Federal] Quarantine, No. 41, effective July 21, 1921. This is en- 
forced by inspectors of the Federal Horticultural Board at all ports 
of entry throughout the country. 
A domestic Federal Quarantine, No. 43, against the European corn 
borer was declared by the Secretary of Agriculture, effective on and 
after March 29, 1920. It is administered by the Federal Horticultural 
Board in cooperation with the Bureau of Entomology. The original 
items of the quarantine included 111 towns in Massachusetts, 3 in 
New Hampshire, 40 in New York, and 1 township in Pennsylvania, 
and prohibited the shipment of the quarantined products during the 
entire year. This quarantine was subsequently amended (September 
2, 1922) to include 161 towns in Massachusetts, 12 in New Hampshire, 
150 in New York, 6 townships in Michigan, 57 in Ohio, and 17 in Penn- 
sylvania, and provides that in the case of corn and broom corn, includ- 
ing all parts of the stalk, cut flowers or entire plants of chrysanthe- 
mum, aster, cosmos, zinnia, hollyhock, and cut flowers, entire plants 
of gladiolus and dahlia, except the bulbs thereof without stems, the 
quarantine and regulations shall apply throughout the year, and in 
the case of all other products for the period between June 1 and De- 
cember 31, in New England territory. It further provides that in 
the case of corn and broom corn (including all parts of the stalk), 
all sorghums, and Sudan grass, from infested areas in New York, 
Pennsylvania, Ohio, and Michigan, the quarantine and regulations 
shall apply throughout the year. 
An amendment of May 1, 1922, provides that the limitation of the 
restrictions of this quarantine, as provided in the rules and regula- 
tions supplemental hereto, to the areas in a quarantined State now, 
or which may hereafter be, designated by the Secretary of Agricul- 
ture as infested by the European corn borer, shall be conditioned 
upon the establishment and enforcement by the State of such control 
measures in cooperation with the United States Department of Agri- 
culture with respect to the designated infested areas as in the judg- 
ment of the Secretary of Agriculture shall be deemed adequate to 
effect the control and prevent the spread of the European corn borer. 
The inspection and certification of all products, cut flowers, etc. 
(except spinach), under quarantine, grown within the quarantined 
area, 1s conducted in the wholesale markets in all cases, except when 
the grower ships directly to points outside of the quarantined area, 
when inspection is made on the premises. 
Where the products are found free from infestation by the Euro- 
pean corn borer, certificates are granted to cover shipment, each 
package being covered by a separate certificate. Such certificates 
(always excepting corn, which can not be certified) permit the 
product to move outside of the quarantined area. Inspection of 
spinach is made only in the field. 
The terms of this quarantine are enforced in the wholesale vegetable 
and flower markets by inspectors employed by the Bureau of Entom-
