Internal improvements" was a nineteenth-century term referring to investment in transportationprojects such as roads, railroads, canals, harbors, and river navigation projects. These public works are an accepted responsibility of the modern state government, but in earlier times the concept of public funding for such projects was new and controversial. North Carolina was so isolated and poor in the early nineteenth century that it was derisively nicknamed the "Rip Van Winkle State." At alarming rates, emigrants fled its stagnant economy, worn-out farmland, poverty, and lack of opportunity. Among the state's greatest handicaps was inadequate transportation. Only a few rivers in the east were navigable, and even these were shallow and difficult to travel. The coast offered few good harbors, and roads, where they existed, were terrible. Under such conditions transportation was slow, inefficient, and so expensive that farmers could not afford to ship their produce more than a few miles.
Some state leaders, such as Governors Alexander Martin in 1791 and Nathaniel Alexander in 1806, asked the General Assembly for money to finance internal improvements. But many legislators and voters strongly opposed raising taxes or increasing government's involvement in internal improvements; for years, the state's role was limited to granting charters to private companies to operate toll bridges, canals, and navigation projects

Slate is much more commonly found in wet areas, especially around rivers in the United States, so it wouldn't be very available to Natives who were more inland.
