Cost data show that if a small group of members wanted to retain their membership but did not want to receive The Journal and The Bulletin, we could save approximately $2.50 on each such member. Alternatively, if a special rate were created for new members who have the above preference, we could not, out of fairness to present mem bership, offer a saving of any more than $2.50. Therefore, if such a membership class were created, the dues could not be lowered from the present $12.50 annual rate to an amount any less than $10.00 per year. We have realized that certain persons do not join The Society because there seems too little inducement to pay the membership fee when they already have fuU access to the publications. If a rate giving substantial savings is offered such members; the Committee feels that a con siderable number of present members would change their status to the less expensive class. The opportunity to ob tain Society membership at $10.00 would be more likely to appeal to persons now paying $12.50 than to those now paying nothing. Dues in The Society are already very low, and cutting rates probably would have little effect on increasing membership. A study of twenty-one technical societies shows that the average dues are about $14.00, and besides that, eleven out of the twenty-one charge an entrance fee about equal to the annual dues. Attempts to obtain new members generally give the im pression that it is the publications of The Society that ap peal most to prospective members rather than the other activities. Accordingly, our first conclusion is, if we made such a class, that making a special rate of $10.00 would not be likely to increase the membership substantially. Furthermore, the Committee feels that The Bulletin is the life blood of The Society for two reasons: (1) all of our advertising revenue comes from it, and (2) it is the mouth piece between The Society and its members. It would be foolhardy to set up a type of membership which would re sult in a member not receiving The Bulletin. Advertising rates are governed by circulation, so we should do every thing to increase circulation of The Bulletin rather than de crease it. Therefore, if we should take the position that every member should at least receive The Bulletin (as the American Chemical Society requires in the case of the News Edition), then the amount of the saving would be cut about in half, and the best we could offer would be a reduc tion in rate from $12.50 to $11.25 per year. Such a reduc tion is too small to accomplish anything but annoyance to the office and is more likely to create problems rather than to improve the position of The Society. In view of all of the foregoing, the Special Committee on Membership Classes recommends no change in the annual membership rates. Respectfully submitted: J. D. Sullivan, R. E. Birch, and D. E. Sharp, Chairman Vol. 20, No. 10 ,
