there are also many who from love of change much prefer to leave the scenes of their childhood. These, too, indicate their preferences by marking the number of the district to which they prefer to be assigned. Second or third preferences may likewise be indicated, so that it would go hard indeed if one could not obtain a location in at least the part of the country he desired, though the locality preference is imperative only when the person desires to stay in the home district. Otherwise it is consulted so far as consistent with conflicting claims. The volunteer having thus filled out his preference blank, takes it to the proper registrar and has his ranking officially stamped upon it." "What is the ranking?" I asked. "It is the figure which indicates his previous standing in the schools and during his service as an unclassified worker, and is supposed to give the best attainable criterion thus far of his relative intelligence, efficiency, and devotion to duty. Where there are more volunteers for particular occupations than there is room for, the lowest in ranking have to be content with a second or third preference. The preference blanks are finally handed in at the local exchange, and are collated at the central office of the industrial district. All who have made home work imperative are first provided for in accordance with rank. The blanks of those preferring work in other districts are forwarded to the national bureau and there collated with those from other districts, so that the volunteers may be provided for as nearly as may be according to their wishes, subject, where conflict of claim arises, to their relative ranking right. It has always been observed that the personal eccentricities of individuals in great bodies have a wonderful tendency to balance and mutually complement one another, and this principle is strikingly illustrated in our system of choice of occupation and locality. The preference blanks are filled out in June, and by the first of August everybody knows just where he or she is to report for service in October. "However, if any one has received an assignment which is decidedly unwelcome either as to location or occupation, it is not even then, or indeed at any time, too late to endeavor to find another. The administration has done its best to adjust the individual aptitude and wishes of each worker to the needs of the public service, but its machinery is at his service for any further attempts he may wish to make to suit himself better." And then the doctor took me to the Transfer Department and showed me how persons who were dissatisfied either with their assignment of occupation or locality could put themselves in communication with all others in any part of the country who were similarly dissatisfied, and arrange, subject to liberal regulations, such exchanges as might be mutually agreeable.
