THE AMERICAN MUSEUM JOUEXAL 



panied by statements of the principal 

 sources of the world's supply prior to the 

 war. Specimens of the foreign ores and 

 of the occurrences which might, under fa- 

 vorable circumstances, be developed in this 

 country, emphasize the vital need as well as 

 the possibilities of domestic production. 



It is in the display of the finished prod- 

 ucts of the war industries, however, that 

 the exhibit makes its distinct appeal to the 

 public. Through the courtesy of a number 

 of prominent manufacturing firms, material 

 has been made available which shows how 

 minerals, and metals extracted from min- 

 erals, are being turned into the tools of our 

 fighting Army and Xavy. In this way one 

 may see the sectional barrel of that very 

 efficient eliminator of submarines, the three- 

 inch naval gun, with its lining of molyb- 

 denum steel, designed to resist the corrosive 

 action of smokeless powder, or can trace the 

 application of mercury from cinnabar, its 

 ore, to the primers charged with fulminato 

 of mercury which explode the hand and 

 rifle grenades now being used to push for- 

 ward our fighting line in France and Alsace. 



One of the most complete series in the 

 exhibit is that which shows the many stages 

 in the manufacture of the nickel-jacketed 

 bullets which are now being dispatched, mil- 

 lions in number, from the rifles, machine 

 guns, and revolvers of our Army and of 

 those of the Allies. These are assembled in 

 a number of mounts which show, step by 

 step, the evolution of a cartridge from a 

 meaningless bit of metal to the smooth, 

 slender-pointed engine of war. A significant 

 detail in the manufacture of the .303 caliber 

 cartridge used in the Lee-Enfield rifles of the 

 British Army, is the little "U. S." which is 

 stamped on the lead insert of the bullet be- 

 fore it is assembled in the shell. 



On the whole, the "war minerals exhibit" 

 has already proved its popularity, judging 

 from the numbers of both soldiers and 

 civilians that have been attracted by it, and 

 it is to be hoped that it will have consider- 

 able influence in bringing to the front of pub- 

 lic interest a phase of our war production 

 which is of primary importance in this 

 period of more than usually important 

 things.— Herbert P. Whitlock.
