Based on this chart, the tabulation for specialtrackwork costs shown in the accompanying table wasworked out. This shows the present variation in pricefor each year, taking the price of 1900 as a base.

Thus, if it is desired to constructa graph for a certain layout or piece of special track-work, all that is necessary is to know the price paidin a certain year, and use the table. Thus, if a companypaid $300 for a tongue switch in 1919, and it is desiredto know the price paid in 1914, then by the use of the table the price would be _gg X 154 = $161.
