IS gral standpoint of the institution the main items are the cost of physical expan- sion, which may be divided into building wages and building material, real estate values, salaries, and cost of equipment. In Table 7 may be found an index of some of these factors, showing the relative change in price, using 1913 as a base. These changes in prices are plotted in Charts 3A and 3B to show the relation between tuition charges and the cost of living, and the cost of building. They are self-explana.tory as they give a moving picture of what has been happening.
