of finely exe'en.ted and artistically colored lantern photographs of the mountainous scenery of British Columbia. Mr. Harrison Souder, Cambria Steel Company, Johnstown, Pa., followed with a paper on " Cuba of To-day Engineering Notes anti Impressions." The speaker gave au account of his observations made during a recent professional trip through the island, illustrating his remarks by showing a number of lantern photographs of interesting engineering works, mmmg operations and other subjects of general interest.
Dr. Samuel P. Sadtler followed with an informal discussion--princlpally from the chemical viewpoint--of the principles of the art of rendering wood, intended for structural uses, "fire-resistant," and commented on the results of a recent investigation of the Ferrell process by the Committee on Science and the Arts of the Institute. Dr. Sadtler's remarks were illustrated by the presentation of a series of samples of various building woods, treated and untreated, which had been subjected to compression and breaking tests by Mr. W.. P. Taylor, Engineer-in-charge of the Municipal Laboratory. The interesting fact was brought out by those tests that the fire-proofing treatment by the Ferrell process did not appreciably impair the strength of the materials.
The thanks of the meeting were tendered to the speakers of the evening and the meeting was adjourned.
