exceeded 20 per cent. The comparative nearness of the local works to the lead 
producing regions of this State and IlUnois and those of Colorado gives the 
industry advantages which are not shared in by the white lead manufacturers of 
any other city in the Union. Cincinnati and Pittsburg, both farther away from 
supplies of blue lead, indirectly bear witness to the importance of these advant- 
ages, by the gradual decadence of their white lead industry. Latterly, however, 
the advantage of being near the lead fields of Illinois and Missouri is not so 
apparent as in former times, but a very small percentage of virgin lead being 
consumed at this time by manufacturers of white lead. Most, if not almost, the 
entire quantity of lead used by them is refined lead produced from bullion carry- 
ing silver by refining works at Kansas City, Omaha, Pueblo, and by the one 
large works here. The uncertainty of getting supplies promptly, and the impur- 
ities in the virgin lead, coupled with other causes, lead to the abandonment of it 
by manufacturers for the refined lead of Colorado and the far west, the supply 
and quality of which can be depended upon. Even in the great Joplin district 
in this State but a small part of the output is suitable for the manufacture of 
white lead, the old worked-out mines immediately around Joplin being the only 
producers of a proper lead. The lead of Short Creek and Galena production, 
while especially adapted to the manufacture of sheet lead and lead pipe, by rea- 
son of the presence of copper in, it is for this very reason unsuited to the making 
of white lead. 
The export trade of St. Louis in white lead is quite large, but it should not 
be inferred from this that shipments are made to foreign countries, for the cheap 
product of England and continental Europe inhibits exports to . markets outside 
the United States. But to all parts of the national territory shipments are made 
regularly, and the aggregate of exports from this market makes a very respecta. 
ble showing. Below we give the exports for ten months in the current year from 
St. Louis :

From this it will be seen that the average monthly exports in the current 
year have exceeded 3,000,000 pounds, from which it may be assumed that the 
record for the entire year will show a total exportation of something like 36,000,-
