This has been, from the first, the work of the International Labour Office, the fixed head-quarters of the Association, which serves as an exchange and clearing-house for all information pertinent to the Association's work. It is in perpetual session at Basle, and to it all reports and inquiries are addressed by the national sections, while from it issue circulars for the sections' consideration and requests for national investigation of problems which appear ripe for international treaty. The spade work of the Association is done by the national sections in their own countries, all action of the Association being necessarily based in the first instance on the reports received from them at head-quarters. There are now fifteen[31] such national sections--an increase of eight on the original group of seven formed in 1901. The actual membership of the Association has trebled in ten years. The seven sections to which belongs the place of honour at the head of the roll, are those of Germany, Austria, Hungary, Holland, Belgium, France, and Switzerland. Great Britain did not form a section till 1904, and it was not till 1910 that the British Government sent official representatives to the biennial meetings. The official representatives constitute a very important element at those gatherings. They attend the plenary meetings and take part in discussions, often contributing hints on their governments' attitude towards a given reform which are invaluable to those who are framing or modifying proposals with a view to government acceptance; and are also frequently present at the sitting of commissions charged with the consideration of detail, where they can hear the opinions and arguments of experts on every important point in debate. When resolutions are before the conference they do not vote--although in respect of voting right they stand on the same footing as other delegates. But on occasion they are not afraid to express opinions on the merits and tendencies of those resolutions which may have a determining effect on the votes of their fellow members, and I have known a few weighty words from such a man as M. Arthur Fontaine,[32] commending a proposal on which feeling was largely divided, to turn the scale at once in its favour. The delegates of a section are elected by the section itself. They may be either men or women, and their number is in proportion to the size of the section, the maximum figure being eight, as far as voting delegates are concerned, but substitute members and experts may be present in addition. The following is a list of the fifteen sections represented at Zurich in 1912: Austria, France, Germany, Great Britain, Hungary, Italy, the United States, Belgium, Holland, Switzerland, Denmark, Spain, Sweden, Norway, and Finland. In addition the following countries and dominions sent government representatives only: Russia, Rumania, Greece, Turkey, Portugal, Brazil, Mexico, and the Australian Commonwealth.
