The question whether or not the row of elms on Harvard street, fronting the college yard, should be removed, was discussed at length by the Board of Aldermen of Cambridge last night. These trees were formerly in the college yard but the increased traffic on Harvard street necessitated the change which now exists. It is now clained that public necessity demands their removal and this question, although debated at length, still remains unsettled. A measure was proposed which if adopted will save the trees and also remedy any inconvenience which the narrowness of Harvard street may cause. This plan provides for the building of a roadway twenty feet wide north of the row of the row of trees. An expenditure of $20,000 will be necessary to accomplish this and in addition it is doubtful if the land can be secured from the University authorities. The question was referred to the Committee on Roads and Bridges.
