To quickly assess the difficulty of the text, read a short excerpt:
DIFFERENT CLASSES OF MEADOWLANDS. The soils of the meadow areas are so extremely diverse that scarcely any single area consists entirely of one class of soil material. The broader and larger areas are frequently found to contain material ranging from coarse sand and gravel, near to present or abandoned stream channels, to the finest silts and clays in regions more remote from the first effects of overflow or in depressed positions where the final flood waters are collected and only deposit thei...r load of sediment through long periods of settling assisted by the final evaporation of the water. The texture of different areas of Meadow and even of different portions of the same area may, therefore, vary from bowlders, coarse gravel, and sand to the finest grained silts and clay. One of the characteristic features of the Meadow is that new acces- sions of material are being received continually in the majority of areas, and, while it may happen that the new material resembles the old in all essential respects as a soil, this is not at all certain to be the case, and any particular acre of land may be covered one year by a heavy silty soil and after a succeeding flood with a deposit of sand or gravel.
