 greater density of population per square mile than has Group 

 II. This latter fact finds some exjjlanation in the difference be-

tween the two groups in soil. Group II has a large area of 

 sand and contains a smaller per cent, of the most fertile soil 

 than does Group I.^ This partly accounts for the difference in 

 density of the population but the steady decline in population 

 noticed in Group I has no such explanation. We find, then, in 

 this small first group conditions more favorable to agriculture 

 that in the second group, but in spite of unfavorable soil this 

 latter section has a population growing more rapidly than that 

 of the older and more densely settled section. In other words 

 the younger portion of the population has for many years been 

 drained away from the towns of the first group, leaving the 

 older and more conservative part to continue on in the economic 

 and social habits that were peculiar to the people of this sec- 

 tion in the early part of our history. 



But with these differences in increase of population are asso- 

 ciated others of a different nature. In the subjoined tables are 

 to be noticed various differences between the two groups of towns
