The club consists of twelve members, and the annual subscription is one hundred and thirty-four pounds. Of this sum twenty-four pounds is allotted to the club expenses, including the club dinners which are held on the first Saturday in every month. Each member in turn acts as chairman at one dinner in the year, afterwards adjudicating upon the problem competition for that month; while at the other eleven meetings he is himself a competitor, the remaining one hundred and ten pounds of his subscription being treated as eleven entrance fees of ten pounds each. The problems are not of a mathematical nature, and were for some time invented and propounded by Leonard, the ingenious head-waiter of the restaurant. The winner receives the whole of the entrance fees, amounting to one hundred and ten pounds; if there is more than one winner this amount is divided equally between them. Thus for his investment of one hundred and ten pounds it is possible that a member may in one year obtain a return of one thousand two hundred and ten pounds, if he is the sole winner of the eleven competitions for which he is eligible. But the minute-books of the club show that in actual practice this has never happened; indeed, the record, made by Mr Pusely-Smythe in 1911, is seven wins, and on two occasions out of the seven he had to share the prize with another successful competitor. It may be admitted that the club has necessarily been of the nature of a secret society. Some of the problems set have been rather curious, and it has occasionally happened that in the course of their practical solution members have been led to do things which might prejudice them in their domestic or social relations, or even subject them to the penalties of the law. It is permitted to add an account of some of the pre-war meetings of the club, various natural precautions being taken to prevent the discovery of the identity of members.
