M. Mabilleau's Lectures.

M. Mabilleau delivered his third economic lecture Friday evening on "Le Probleme des retraites ouvrieres devant le Parlement et l'opinion." He discussed the system of providing for the worn out workmen in France; and showed that it is more economical to have a regular list of pensioners than to support paupers in a poor house, according to the English custom.

M. Mabilleau will deliver his fourth and last lecture on social questions in France in the Fogg Lecture Room this evening at 8 o'clock. His subject will be "La Co-operation en France."
