Letters from the Harvard Fund class agents are being mailed this week to the members of all classes graduated from 1853 to 1926, according to an announcement made last night by the Harvard Fund Council. Special letters are also being sent from the Fund Council office to former members of the graduate schools. The first contributions to the Fund have already begun to come in in large numbers.

These letters were written individually by the various class agents, and through this more intimate and direct method of appeal, the officers of the Council hope that a large number of new subscribers will be recruited.

Letters to members of the class of 1927 will go out by the first of next week, it was announced. Lawrence Coolidge, of Boston, is the 1927 class agent.

The percentage table of the standings of the various classes in regard to the number of contributors has developed into one of the best stimuli to the Fund.

The agent for one of the oldest classes, wrote in his letter: "Let us therefore try to double 18--'s percentage and get fourth place on the list. Do not hesitate to send a dollar or two, unless you really want to give more. Of course this, our---anniversary year with its financial burdens, is not favorable for a great showing, but let us do our best."
