This chapter describes the processes involved in the transport of material over hillslopes. Hillslopes provide the gradients enabling material to be transported from the slopes themselves towards the valley bottoms, directly by gravity alone, or by water flowing down over the surface. Gravity has the potential to transfer material downslope if the material resistance to counteact it is insufficient. Similarly, water and wind flowing along the surface exert a drag on soil particles and have the potential to entrain material. After the gradient has fallen below a critical threshold to keep the...

This book written by J. Roy Guyther, MD.is intended for the sole purpose of entertaining the reader. It is not a scientific text, although it may reveal the philosophy of the writer about the practice of general medicine in a rural setting. It is nothing more and nothing less than a series of short stories depicting some fascinating encounters of an average country doctor in the last half of the twentieth century. This era has been called the golden age of medicine because of the many technologic and therapeutic advances achieved. Before 1940, diagnostic technology was limited chiefly by...
