<P> Also on December 1, 1969, a second lottery was held with the 26 letters of the alphabet . Among men with the same birthdate, the order of induction was determined by the ranks of the first letters of their last, first, and middle names . Anyone with initials "JJJ" would have been first within the shared birthdate, followed by "JGJ", "JDJ", and "JXJ"; anyone with initials "VVV" would have been last . </P> <P> People soon noticed that the lottery numbers were not distributed uniformly over the year . In particular, November and December births, or dates 306 to 366, were assigned mainly to lower draft numbers representing earlier calls to serve (see figure). This led to complaints that the lottery was not random as the legislation required . Analysis of the procedure suggested that mixing 366 capsules in the shoe box did not mix them sufficiently before dumping them into the jar . ("The capsules were put in a box month by month, January through December, and subsequent mixing efforts were insufficient to overcome this sequencing .") Only five days in December--Dec. 2, 12, 15, 17 and 19--were higher than the last call number of 195; had the days been evenly distributed, 14 days in December would have been expected to remain uncalled . From January to December, the rank of the average draft pick numbers were 5 4 1 3 2 6 8 9 10 7 11 12 . A Monte Carlo simulation found that the probability of a random order of months being this close to the 1--12 sequence expected for unsorted slips was 0.09% . </P> <P> Draft lotteries were conducted again in 1970 (for those born in 1951) and from 1971 to 1975 (for 1952 to 1956 births). The draft numbers issued in 1972 were never used the next year to call for induction into service, because the last call was December 7 and authority to induct expired on June 30, 1973 . </P> <P> The 1972 to 1975 lottery numbers were used to call some men born 1953 to 1956 for physical exams . The highest number called for a physical was 215 (for tables 1970 through 1976). </P>

When did the draft end in the 70's
