[Sidenote: Proved by analysis to be unsurpassed, if equaled.]
By way of comparison, I next introduce a table of analyses, which begins
with what Mr. Phineas Barnes, in his report on the steel industry of the
United States (1885), gives as a typical steel ore from the best
American mines. The second analysis gives the average of fourteen
analyses of the best Lake Superior steel ores. The third is a typical
steel ore from the Iron Mountain of Missouri. The fourth is the average
of all the analyses of the magnetic ores of the Snoqualmie Valley, which
name I give to them to distinguish them from similar ores on the east
side of the Cascade Mountains, of which I have no analyses:
