Probably the largest number of such maps yet brought 
together were on exhibition at Chicago. Brought together 
must here be taken in a Pickwickian sense. To be sure 
they were in the White City, but it required several days to 
find and see them, and when found direct comparison was 
impossible. If they had been exhibited by the modelers or 
artists as samples of their work, they would naturally have 
constituted a group by themselves and been gathered in a 
single building. But this stage has not yet been reached; 
so the geographer interested in the art was forced to spend 
some time and care in searching out the examples of it on 
exhibition. Still the search was well worth making, since 
good relief maps are powerful aids in teaching, aids that are 
of value not only for the schools but for the public. Recog¬ 
nition of their value will, furthermore, stimulate their pro¬ 
duction, and with their increasing number it is in every 
way desirable that lofty ideals be conceived and striven for. 
Enough progress has already been made to reveal merits 
and defects and to suggest principles of general application— 
principles that, while still leaving many questions unan¬ 
swered, will yet make possible the avoidance of certain grave 
defects and waste of time and energy. 
Size of Relief Maps .—The relief maps exhibited in Chicago 
ranged in size from 4 or 5 square feet to nearly 1,000 square 
feet. Massachusetts, for example, with an area of about 
8,300 square miles, was modeled on a scale of 4 miles to an 
inch, yielding a model 2| by 4 feet, or 10 square feet. The 
neighboring and slightly larger State of New Plampshire, 
with an area of 9,000 square miles, modeled on a scale of \ 
mile to 1 inch, }delded a model 15 by 31 feet, or of 465 
square feet. Of Massachusetts we have a detailed topo¬ 
graphic survey on a scale of 1 mile to 1 inch; of New Hamp¬ 
shire we have no detailed topographic survey. These two 
models, therefore, form an instructive contrast in the matter 
of size. Standing before and rather near the Massachusetts 
model, we may, without moving, take in the topographic 
relations of the whole State. Moreover, the topographic data 
used in its construction are sufficiently detailed and precise
