making Has Taken Great Strides, So That
Now Only Very Small Portion of tho
Earth Cannot BE shown.
Good maps are almost necessity of our
daily lives. There are few interests or en-
terprises among civilized peoples which do
not require maps as part OF their work. |

enormous masses of new geographic infor- |
nation has been collected, and it is inter
esting to observe the effect of these fresh |
accumulations upon the maps.
If we know little about region, 1t is
easy to make u map Of the area on very
small scale, As our knowledge grows, maps
must be made on larger scales in order to
present the information clearly. OF late
years more facts have been learned concern
ing Africa than any other part of the world
Twenty years ago it was useless to make
maps Of most parts of Africa on a scale
larger than l.5,00O,000 (7S90 miles to the
inch); now we have n map of that continent
on a scale Of l.2,000000 (3l56 miles to the
inch) and DE Lannoy de Bissy, the author
of that great work, is of the opinion that in
1 five years more photographers will not be
able to do justice to our knowledge of At
RIGA on scale smaller than Is miles to the
inch. Considerable parts of inner Africa
are now mapped on IA scale of from to IL
/ miles to the inch
4 The cartographers' art has made such
progress within the past 20 years that
those who have any idea how much infor-
motion may now wildly be set forth on
map are not content to see it show Il coun-
try merely as II piece of land limited by
political boundHries-they expect to see
the Topographic and cultural features ac-
curately expressed, and the fact that the
best maps nowadays are made to convey
:! larger and more varied amount of informa-
ton than formerly has also had the effect
!, Of charging the scale of mapmaking. We
now have maps on u scale of 100000 (3.l5
miles to the inch) of nearly the whole of
i Europe large regions of North America
/ and parts of Africa and India. More than
: twothirds of the coast lines of continents
2 and important islands have been mapped
| on large scale, and parts of South Amer
! lea, Australia and n large portion of Asia
have been mapped on scales varying from
1 Is to lG miles to the inch.
