As Madeira resumed his chair at his desk, he seemed to brace himself toward some sort of finality. His voice, when he spoke, was ominously quiet for a noisy man's voice. "Here's something about the country in general," he began slowly, dispassionately, "that I think might interest a fellow who is considering coming down here either to mine or to farm. See what you think of this: 'It was in 1874 that the first carload of zinc ore went up to the zinc works in Illinois. That was the beginning. Heretofore Missouri had been supposed to be agricultural only, but here was a new Missouri, whose wheat and corn and fruit wealth was found to be supplemented by a mineral wealth of mammoth greatness. Settlers who wanted to mine began to come in, towns to spring up, and capital to be invested. The country was developed with lightning-like speed. From the Joplin stretch as a nucleus, lines of development have been steadily projected since 1874 to this day. There are not a great many undeveloped big acreages of land left in any of the southern Missouri counties. Of the few that remain by far the largest and most promising is the country known as the Tigmore Stretch. A remarkable feature of this region, besides its great agricultural possibilities, is that the surface exposure in the hillsides shows distinct mineral-bearing horizons, beds of zinc carbonates, whose promise of zinc sulphide at a greater depth is absolutely reliable. That it needs only deep shafting and drilling to unearth more remarkable riches than even Missouri herself has as yet yielded up, is evident from the outcrops'--by the way, gentleman," Madeira here interrupted himself to say, still in his quiet, dispassionate tone, "Salver has spent a good many days in the hills lately, and he has decided that the deeper-seated sulphides are just as surely in the hills as are the carbonates. He has done a lot of verifying. Aint that right, Salver?" Salver shuffled his feet and said yes, that was right, and Madeira read again from his notes, picking out bits here and there, and beginning each time, "Now take this. See what you think of this," his voice staying monotonously even.
