pense of fuel bills, and so the compoundsteadily made its way into favor amongthem. Towards 1872, when nearly allmerchant steamers were using compoundengines and the navy had none, an inves-tigation was made by Parliament. At thisinvestigation evidence was given that com- cluded that the use of water-tube boilers,was necessary in the navy. They startedloff at a tremendous pace, wliich landedthem upon the Belleville boiler. Whatcame of this extraordinary rush of prog-ress is another story. Lecture on the Chemistry of Iron andSteel. Mr. H. F. J. Porter, of the BethlehemSteel Company, of South Bethlehem, Pa.,gave a very interesting illustrated lecturebefore the Brooklyn Institute of Arts andSciences on November 20th. His subjectwas the Development of the Forging In-dustry, and he showed pictures of steeltools found in Assyria which were made1500 B.

COMPOUND ENGINES. Many steamers belonging to the mer-cantile marine were using compound en-gines with success, and the navy had tofollow suit. Great diversity of opinion^or rather opposition, not to mince thetruth—existed among naval men as to thevalue of the compound. They did notwish to have anything to do with it; butpublic opinion forced the Admiralty to try pound engines working with 60 poundspressure effected a fuel saving of from 30to 35 pe cent,
