EXPLANATIONS TO THE CONSULTING INDEX.

To ascertain the position on the Map of any place mentioned in the Index, observe the
letters annexed to it in the fourth column; then find the corresponding letters on the top
or bottom and sides of the Map; from these letters pass the eye along the ranges due
north or south, and east or west, until they intersect: in the square in which they meet,
the place sought for will be found.

It will be observed, that every page of the Index contains two ranges of four columns
each; the first of these shows the names of Places, the second the class to which they
respectively belong, as Cities, Towns, &c.; the third column points out the Country in
which places are situated; and the fourth, the reference letters that correspond with those
on the top and bottom and sides of the Map, and by means of which the position of cities
and towns may be found. For example, Aaik, the first name in the Index, is an Island
in North America, the Reference letters attached to which are A b; on examining the
Map, A will be found near the left corner at the top, and b, the second letter, in the left
hand border in proceeding downward from the top of the Map: by the plan mentioned
above the square containing Aaik will be found. The second name in the Index, is Aal-
borg, a town in Denmark, letters M c; this will be found, according to the rule stated,
near the the middle of the Map, and about one-third of the breadth from the top; and by
the same simple means every place mentioned in the Consulting Index may be readily
ascertained.

The figures attached to a few of the names in the first column of the Index, signify
that those places are represented on the Map by the figures attached to them; this occurs
only in the cases of the governments of European Russia, a few of the minor German
States, and in two or three provinces in Bolivia.
