The metals referred to by Mr. Symons are as follows: Figure7—Copper, tin, lead and phosphorus; a phosphor bronze, firstmelting. Figure 8—Copper, tin, lead and phosphorus; a phos-phor bronze, remelted repeatedly. Figure 9—Copper, tin andlead; first melting. Figure 10—Copper, tin and lead after re-peated meltings. The last mentioned alloy is made by the AjaxMetal Companys process, which assures the homogeneous dis-tribution of the lead. The peculiar action of lead in alloys re-.

The posts D are spaced about 6 feet apart betweencenters longitudinally of the car, and the width is divided upinto three stalls. The bottom of the posts D are dropped intopockets let into the floor, and rest on springs under thepockets. The partition bar A is shown with its extensible partat the left. A larger sized detail of the end of this bar and alsoof the pocket and spring for post D are shown in the illustra-tion, giving a better idea of the construction than is possiblefrom the general elevation. The method for securing the postsD at the top, as shown, makes it clear why the fittings can beso quickly applied where necessary to use a car for stock trans-portation. Those at the Master Mechanics and Master CarBuilders Convention at Saratoga in 1898 will remember thefavorable comments made on the baggage car fitted up
