Writing from the 19th century United States tends to be relatively complex, but grammatically so, rather than the sort of existentialist run-on nonsense with which we're latterly so often abused. Here, as a reasonably representative example, is the first paragraph of
The Last of the Mohicans [1]:
> It was a feature peculiar to the colonial wars of North America, that the toils and dangers of the wilderness were to be encountered before the adverse hosts could meet. A wide and apparently an impervious boundary of forests severed the possessions of the hostile provinces of France and England. The hardy colonist, and the trained European who fought at his side, frequently expended months in struggling against the rapids of the streams, or in effecting the rugged passes of the mountains, in quest of an opportunity to exhibit their courage in a more martial conflict. But, emulating the patience and self-denial of the practiced native warriors, they learned to overcome every difficulty; and it would seem that, in time, there was no recess of the woods so dark, nor any secret place so lovely, that it might claim exemption from the inroads of those who had pledged their blood to satiate their vengeance, or to uphold the cold and selfish policy of the distant monarchs of Europe.
This was an extremely popular novel in its day, in the literal sense of "popular" - by no means was it read exclusively among the elite, and indeed the literary elite of the time tended to regard it despite occasional equivocation as generally of good quality - although Twain, with his usual inimitable style, quite rightly suggests [2] that Fenimore's work in general should have been considerably less well regarded than it was. Nonetheless, that it was so regarded, and so widely read, can hardly be brought into question.
