INTRODUCTORY STATEMENT
There have been prepared by the authors and are here presented
 a number of tables which are intended to meet the ordinary
 requirements of the valuation engineer and the economist.
Where values are not noted in the tables for every year from
I to 100 years, as is the case in some of the tables, methods are
indicated whereby values can be combined, or other tables can
be called to aid.
It is believed that all values have been noted with sufficient
accuracy, that is with a sufficient number of decimal places to
meet every ordinary demand.
Particular reference should perhaps be made to a novel feature
incorporated in Table 33, entitled “ Amortization or Depreciation
 and Remaining Value.” It will be noted that sub-headings
have been given to some of the columns in this table. By use
of these sub-headings, whenever the remaining life or expectancy
of any article new or old is known it is made possible to take out
of the table in the appropriate column its remaining or present
value.
Because this set of tables is a supplement to and a part of
“ Valuation, Depreciation and the Rate-Base” the paging and
table numbering have been preserved. The set covers pages 319
to 475 and Tables 19 to 33. Where in this Supplement other
pages or other tables are referred to, they will be found in main
portion of ‘“ Valuation, Depreciation and the Rate-Base.”
