Harvard's Work in Road-making

In a letter sent to the press of Massachusetts in the interests of state roads, Colonel A. A. Pope makes the following allusion to an interesting branch of the work done at the Lawrence Scientific School:

"Progress has been made in the laboratory work on the road building stones of the state. Experiments of this kind are carried on at Harvard University in the Lawrence Scientific School, whose dean, Professor N. S. Shaler, is a member of the Highway Commission. The chief aim of these inquiries has been to determine the qualities which constitute fitness for road making. This will be of value to the Commission in enabling them to utilize the road material near at hand, and thus lessen the cost of construction. As this phase of the work progresses maps are made showing the location of all deposits suitable for road building."
