[We invite all men in the University to submit communications on subjects of timely interest.]

To the Editors of the CRIMSON:

Permit me through your columns to call the attention of students in all the departments of the University to an opportunity for social service in Cambridge. During the next few days the Prospect Union aims to put before every workingman in Cambridge the opportunities for education that Harvard is providing for him through the Union. For this work a large number of men, are needed at once as speakers, advisers teachers, etc. There will be almost 200 meetings of labor unions, clubs, lodges, factory groups, etc., within the next month to which volunteers will be assigned to describe the work of the Prospect Union. Men interested in any department of the work are invited to visit the Union and especially to attend the meeting of workers, which will be held at the Prospect Union, next Monday evening at 8 o'clock. A. H. ELDER 3L., President.   P. N. CRUSIUS '09, Secretary.
