Question

How is this map different from a typical US map?

Answer 1

1, In this map all state's names are redacted and rewritten.

As you can see, the name of the state in the map are crossed and rewritten with a name that would not be familiar if mentioned to local citizens of united states. This indicates that other people beside citizens of united states were using this map.

Answer 2

1. A typical map may have some additional components that are not clearly identifiable in 1900's one. Some examples may be:

• Scale: maps, in general, are pretty accurate in terms of the relationship between distances on the map and the actual distances on Earth. This may not be the case for the "A Map of part of THE UNITED STATES."
• Grids: series of lines that creates squares or rectangles, which helps locate places.  The 1900's is missing this imp.

In addition, it is a map of a portion of the US territory.

2. The common thing among the new names on the map is that they are Irish. It is observable that the map was modified (by crossing the original names) in order to serve the ongoing Irish immigrants to locate in the territory.

3. A considerable number of Irish immigrants started to move to the US throughout the 18th century, arriving to New England, Maryland, Pennsylvania, North and South Carolina and Virginia. Nonetheless, the great potato famine caused a another massive migration and by 1845 settlements were established in New York and Boston. For these tow waves of immigrants, the map was a necessary tool to identify known places where to establish. It is also important to note that they were limited by language barrier, so having maps in their mother tongue supposed an extra aid in an unknown place.
