The latest addition to the length of Harvard's subterranean passages, a tunneled walk connecting Randolph Hall and Westerly Court with the central unit of Adams House, has finally been completed and was opened for use last Saturday. As a result of this final boring, the swimming pool in Westerly may be reached from either Randolph, or from the central unit of the House, where the dining and common rooms are located. At present the construction of the new building of Adams House is rising toward completion on the site of the former Russell Hall.
