Predeparture Inspection Outside Continental United 
States. The predeparture inspections of aircraft and of 
the baggage of airtravelers continue to expand in Hawaii, 
Puerto Rico, Nassau, and Bermuda. The number of 
aircraft given predeparture clearance for flight to the

The Second Line of Defense: Cooperation by other officials and by the 
public--individuals and groups--is so essential to an effective plant 
quarantine program that it is considered the second line of defense. 
Continuing efforts are being made to expand this participation, which has 
proved so helpful ''to multiply the hands" of the Plant Quarantine 
Inspectors. 
Besides the sister-border clearance agencies, i.e., U.S. Customs 
Service, Immigration and Naturalization Service, and the Public Health 
Service, who work together with the Agricultural Research Service 
inspectors ona more or less formal arrangement, many agencies 
cooperate informally, and notify inspectors of any clue to a pest-risk 
situationthat they encounter. Helpis givenbysuchagencies as the Armed 
Forces, the U.S. Postal Service, the U.S. Travel Service, the Food 
and Drug Administration, and other agencies of the Department of 
Agriculture. State and local quarantine officers also give valuable 
cooperation. 
The traveling public is increasingly helpful as it gains understanding of 
the serious consequences that can come through introducing pests in 
baggage. Here is where themain effort to strengthen this second line of 
defense was expended during the year. 
The American flag airlines met with the Department in July 1965,anda 
committee consisting of industry and government representatives was 
formed to expedite plans toprovide notice of agricultural quarantines to 
airlinetravelers. Methods proposed include use of a standardized notice 
of quarantine restrictions in all airline materials given to travelers; 
training materials for airline personnel so that they can better advise 
travelers about agricultural quarantine restrictions; use of movies and 
exhibits in airports and of movies aboard airplanes; and expansion of 
efforts to obtain cooperation of travel agents to inform travelers at the 
time airline tickets are purchased.
