BRASS GOODS STANDARDIZATION
Sub-committee on Standardization of Water Works Brass Goods of the Brass Manufacturers’ Association Makes a Report
The sub-committee on Standardization of Water Works Brass Goods of the National Association of Brass Manufacturers, of which Adolph Mueller is chairman, has made the following report and recommendations to that association. Copies of these recommendations have been sent to the water works associations and there will be a number of matters which no doubt will have to be carefully analyzed by committees of the associations before the final action on the adoption of the recommendations is taken. There are committees on Standardization of Water Works Brass Goods in Connection with Services both in the American and the New England Water Works Associations.

Poster Contest Feature at Convention
Milwaukee carried off the honors at the Poster Contest of the Gamewell Company at the I. A. F. E. Convention at Toronto. One hundred and fifty posters were submitted and seventy-six of the best ones were displayed at the Gamewell Booth. Four chiefs, Murphy of Buffalo, Henderson of Kansas City; Ten Eyk of Hamilton and Henderson of Bradford, Pa.; were the judges. George Fischer of Milwaukee won the first prize of $300. Chester Crow of Chicago won the second prize of $100. D. D. Stumpf of New York was awarded third prize. O. H. Mitchell of Chicago and Ernest Forshaw of New York were awarded fifth and sixth prizes respectively and seventh and eighth prizes went to T. T. Grimsdale of New York and Mr. Schwartz of New Jersey. Twenty other posters were awarded honorable mention for excellence of idea, composition and coloring. Posters were received from all parts of the United States and Canada and the task of deciding the best was a most difficult one. The judges finally decided on a poster which emphasized the idea that most cities had an adequate number of parks, natatoriums, public buildings, paved streets, etc., and yet were strangely deficient in the number of fire alarm boxes. The judges were complimented on their choice by all who viewed the exhibition. In addition to the poster display the Gamewell Company had a complete display of up-to-date aparatus. An old wooden fire alarm box, one of the first boxes put in service in this country, attracted much attention, especially as it was displayed alongside one of the most modern Peerless boxes. The shunt type box for the protection of business concerns and the combination fire and drill box used in schools were also given close inspection by the chiefs, who realized the need of protection for industrial concerns and schools.
The Northern Electric Company Ltd., the manufacturers and distributors of Gamewell apparatus in Canada, had the booth adjoining the Gamewell booth. Their booth was the gathering place of the Canadian chiefs who are determined that the cities in the states shall not have more adequate fire signaling protection than their own cities.
