Expedition to the Bahamas.

The Geographical Society of Baltimore is organizing a summer expedition to the Bahamas under the leadership of Professor G. B. Shattuck, of Johns Hopkins University. The party will sail from Baltimore in a specially chartered vessel early in June. Each of the twenty members will contribute $150, which will cover all expenses. Professor Shattuck wishes two more assistants on his geological staff, and men in the University who may wish to go on this expedition should communicate with him.
