The former plan would have in large measure merged the institute in Harvard University; the present plan seems to use the funds of the university for the support of the institute. It may, however, be that both institutions will gain by the arrangement and both President Lowell and President Maclaurin emphasize the fact that educational institutions do not exist for their own glory, but for the welfare of the community as a whole, and that the combination of resources of the two institutions will provide a school of engineering at present unequalled in this country and perhaps in the world.

TRACK SCALE TESTING EQUIPMENT OF THE BUREAU OF STANDARDS

About four years ago the bureau began to investigate the subject of railroad track and elevator scales with the idea of standardizing them. It soon became evident that the greatest diversity of opinion existed among the experts regarding these subjects and that there was very little reliable information on the subject. In order to secure reliable data, and to be in a position to test large scales upon the request of the railroads, elevators, shippers or state officials the bureau secured an appropriation of $25,000 from congress last winter to purchase an equipment and to provide the necessary expenses for its operation. This appropriation became available July 1, 1913. The equipment was completed October 1, and over thirty-five track scales were investigated in Connecticut, Vermont and New York during the following six weeks. Throughout this whole period the car met with every expectation and is ready for further tests.

The car designed by the bureau differs radically from those ordinarily used by the railroads. The usual test weight car is a heavy compact steel body with four wheels and a base of approximately six feet. It may weigh from 25,000 to 80,000 pounds and has
