Besides the fretiuent arrangeiiient of these liills and ridges of 
till ill groups and somewhat defruite lielts. whieh are from a few 
miles to 10 or 20 miles wide, with iutervening lielts or irregular 
areas destitute of diumlins, a still more noteworth}- feature of their 
geographic distribution is found in their occurring thus ujjon some 
extensive districts, while they are utterly wanting on larger portions 
of the great glaciated areas of North America and PiUroi)e. On this 
continent it seems probable that the districts where they are found, 
ranging from southern New Brunswick and Maine to northwestern 
Manitoba, ma}' haA'e been uncovered contemporaneously from 
the ice-slieet during the same general stage of its tinal recession. 
Mr. Robert Chalmers has observed numerous drumlins on the 
east side of lake Utopia and between the Magaguadavic and 8t. 
Croix rivers in Charlotte, the most southwestern county of New 
Brunswick.* Under the name '• whalebacks. ' Mr. G. F. Matthew 
describes these and other drumlins in the southern part of this 
province on an area extending from the St. Croix tiliout 00 miles 
east to Upham townshiixt 
Drumlins are reported in iMaine by Prof, (leorge TI. Stone, the 
lenticular type prevailing in the western part of the stnte, while 
toward the east they also take the form of long ridges. In size 
and numViers, however, the}' are descriljed as inferior to the drum- 
lins of New Hampshire. Massachusetts, and New York. J 
The earliest mapping of drumlins in this country was done l»y 
the writer in 1878, under the direction of Prof. C. H. Hitchcock, 
for the Greological Surve}' of New Hampshire.'!! Nearly 700 
drumlins were noted in the southern half of this state, besides 
about 175 lenticular slopes of till. Farther north in New Hamp- 
shii'e such accumuhitions are absent or very rare. Some 130 
drumlins in adjacent portions of northeastern Massachusetts and 
southwestern Maine were also noted on this map. The most im- 
portant feature of the distribution of the drumlins in New Hamp- 
shire is their occurrence chietiy upon three l»elts which vary from 
5 to 20 miles in width and extend 2") to 30 miles from northeast
