SOME HIGHLIGHTS OF THE YEAR 
Mexican border traffic, In1960 over 22.5 million vehicles crossed 
into the UnitedStates from Mexicothrough border ports, an increase 
of 1.5million over 1959. This compares with the average increase 
of a million a year, this upward trend having existed since shortly 
after World War II, At Nogales, Arizona - the principal port for 
the entry of Mexican winter vegetables, atotal of 11,274 railway 
carloads and 6,777 truckloads (a total equivalent of 20,000 carloads) 
were given plant quarantine clearance. The trend of recent years

some on more than onevoyage. Of these 122 vessels, 85 were found
