Mr. Frank B. Gilbreth, a general contractor of New York City, will deliver an illustrated lecture on "Motion Study as Applied in Industry" in Pierce 110 this evening at 8 o'clock. The lecture will be under the auspices of the Engineering Society.

Mr. Gilbreth is one of the few contractors who issue contracts on the basis of the cost plus a fixed sum. He is the author of several books on construction problems, and was the contractor of Dr. Sargent's gymnasium, the Cambridge Electric Power-house and many buildings in Boston and New York, as well as on the Pacific Coast. Mr. Gilbreth has done much to put contracting on a higher standard in this country.
