To quickly assess the difficulty of the text, read a short excerpt:
Similarly the majority of other tillage operations must be carried on through the use of a single animal for motive power and through the employment of the light-weight, small-sized tillage instruments. Both seeding and planting must be done largely by hand, and the grain crop must be secured through the use of hand implements. Even the thrashing of the grain becomes a matter of some difficulty, since only small-sized oufits can travel the moun- tain roads to thrash out the grain. There are thu...s topographic limitations upon the cropping of these soils which not only decrease the efficiency of both types in the production of the common crops, but also, over a considerable proportion of their extent, prevent the introduction of special crops suited to these soils and to their climatic environment. Although the Porters loam and black loam occur only over a narrow range of latitude, the great range in altitude occupied by the types gives rise to considerable differences in the climatic sur- roundings.
