the plain stretches away unbroken to the foot of the Laurentian 

 country. 



As has been remarked by Sir Archibald Geikie : ' 



The word "mountain" is properly speaking not a scientific term. It 

 includes many forms of ground utterly different from each other in size, 

 shape, structure, and origin. In a really mountainous country the word 

 would be restricted to the loftier masses of ground, while such a word as 

 " hill " would be given to the lesser heights. But in a region of low or 

 gently undulating land, where any conspicuous eminence becomes important, 

 the term "mountain" is lavishly used. In eastern America this habit has 

 been indulged in to such an extent that what are, so to speak, mere hum- 

 mocks in the general landscape are dignified by the name of mountain. 



The hills under consideration, while by no means "mere hum- 

 mocks," being situated in such a country of low relief, seem to 

 be higher than they really are and are always referred to locally 

 as " mountains." 



These mountains, whose positions are shown on the accom- 

 panying map (Fig. i), are eight in number, their names and 

 their height above sea level being as follows : 

 Mount Royal --------- 769.6 feet 



Montarville or Boucherville mountain - Not yet accurately determined 

 Beloeil --------- 1,437 feet (Leroy) 



Rougemont --..-. \

Yamaska ------ ^ -' -' 



Shefford -------- 1,600 feet (Dresser) 



Brome --------- 1,440 feet (Dresser) 



Mount Johnson or Monnoir ------- 875 feet 



Brome mountain is by far the largest of the group, having an 

 area of 30 square miles. Shefford comes next in size, having an 

 area of rather less than nine square miles, while Mount Johnson, 

 which is very much smaller than any of the others, has an area 

 of only .422 of one square mile. 



Of these eight, the first six, as Logan ^ notes, "stand pretty 

 nearly in a straight line," running approximately east and west, 

 Mount Royal being the most westerly, and the others following 

 in the order in which they are enumerated above, until Shefford 

 mountain is reached, which is the most easterly member of the 

 series. The distance from Mount Royal to Shefford is fifty
